There are a series of existing water treatment plants where the client wishes to power the plant using renewable energy. The project requires the installation of a wind turbine and PV panels on site. Our end has been to create a visualisation to examine the visual impact of the turbine and PV panels, particularly in relation to the nearest dwellings. Some screen shots below. Not photorealistic but getting a good balance between time spent doing the modelling and quality achieved from Infraworks. The majority of videos, demonstrations and marketing material from Autodesk is aimed at larger scale projects but IW is well suited to smaller scale projects also.</span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">I was working on a job recently and needed some different type stone hatch patterns. A Google search should give you plenty of options - I found some useful ones here - </span><a href="http://www.eldoradostone.com/trade-community/specification-library/hatch-patterns/"><span style="font-family: Verdana, sans-serif;">http://www.eldoradostone.com/trade-community/specification-library/hatch-patterns/</span></a><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">Once you have downloaded the files (they will be in .pat format) what do you do with them? The best solution is to copy all of your custom hatch patterns to a folder (C drive or network) and then set up a Support File Search Path pointing to this location. To do this type OPTIONS in AutoCAD. On the files tab select Add and browse to the location where you saved your hatch patterns.</span><br />

Your point file might be in one of the typical formats (PENZD) when you open it and look at it but C3D still doesn't appear to recognise it. This usually happens because there is something in the file that C3D doesn't understand. Typically this will be a number in a column where it is expecting alpha characters or vice versa. Check your point file to make sure that, for example, the 'P' column contains only numbers. Looking at my file I see that the first point was a base station and this point does not have a number, rather it uses the STN code in the 'P' column.<br />

C3D doesn't know what to do with the STN as it is expecting a number. Edit the point file and try reimporting and it should work ok.Donal McMorelandhttp://www.blogger.com/profile/02440880792459948241noreply@blogger.com0Slieveaun, Co.

The label used in the band set above is taking the sample line name as it's value. The sample line name does not update if the sample line moves. What you can do to add a dynamic label is delete the part of the band set that is displaying the chainage and then insert a label by editing the section view style instead.<br />
<br />
First, select the section view and click on Section View Properties on the ribbon. In the bands tab delete the chainage band, see below:<br />

Next select the section view, right click and select edit section view style. In here on the Graph Title tab we will add a label in the graph view title that reads the section view chainage, see below:<br />

Worth posting as it can save literally hours for anyone that is manually stringing survey points - (If you don't have Civil 3D set up to automatically process survey data). The drawing used below is from the Civil 3D Essentials book by Eric Chappell.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">If you have surveyed a string of points and the numbers are sequential then you can use transparent commands when you are joining them in Civil 3D to speed up the process. Below I have a fence that was surveyed from start to finish (1 to 5 in the image).</span><br />

<span style="font-family: Verdana, sans-serif;">To string these quickly start the 3DPOLY command (or polyline command). Select your start point by clicking with the mouse. When it looks for the end point type <strong>'PN </strong>(apostrophePN). Then press enter. Type <strong>123-150</strong> and press enter. Civil 3D will automatically string all the points between the numbers for you.</span><br />

<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtXij4OA_ySlHLXXAUv2DrwcejsunWm89aIRjyrR-aKnEaC03Jk8Tey-eyc2AD2hq0NJghEqUUJo_xLEE1dq3JrFbxoevrph8X2ER95dp4w1Icydc66kiGDQNIH6Oz6R8Awlm7zo4eob-D/s1600/2014-01-08_1643.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtXij4OA_ySlHLXXAUv2DrwcejsunWm89aIRjyrR-aKnEaC03Jk8Tey-eyc2AD2hq0NJghEqUUJo_xLEE1dq3JrFbxoevrph8X2ER95dp4w1Icydc66kiGDQNIH6Oz6R8Awlm7zo4eob-D/s1600/2014-01-08_1643.png" height="278" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">If we want to create a surface in Civil 3D from these points we will need to add in the blocks (cross where the point was surveyed in image above) if they have levels. If they have no levels then second best is to add in the text (13.18) if this has a level. (the insertion point of the text wont be at the same location as the surveyed point but the difference this would make for a topo survey would be negligible in most cases). In my case neither has any level information - they are both at zero elevation. There is a workflow available that uses queries in Map 3D to raise the text up the elevation value in the text itself. I am going to show a different approach here using the AutoCAD Data Extraction command to create a csv file which contains the x ,y coordinates of the text and also the contents (elevation). we then import this back into C3D as cogo points.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">First isolate all the 'elevation' pieces of text. Then type DATAEXTRACTION. On page 1 of 8 create a new extraction and save it. On 2 accept the defaults and click next. On 3 tick Text or MText - whichever the elevation text is, click next. On 4 on the RHS tick Geometry and Text, on the LH pane tick Contents, Position X & Position Y, click next.</span><br />

<span style="font-family: Verdana, sans-serif;">On 5 untick Show Count Column and Show Name Column, click next. On 6 select 'Output to external data file' and choose a save location and file type. Step 7 is skipped if you just export to external file so on 8 just click finish. Job done. You now have a csv file with x,y,z for the survey points (with the point location at the insertion point of the text but close enough for a lot of surveys!)</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">You can then inport this back into Civil 3D as you would normally and create cogo points from it. One thing to be aware of is the first line of your csv file will be header info so delete this before trying to import into C3D or it will fail.</span>Donal McMorelandhttp://www.blogger.com/profile/02440880792459948241noreply@blogger.com1Slieveaun, Co.

Generally I have found that there will not be a report that gives you exactly what you want. Some reports will give you one bit of what you want and also probably a lot of information you don't need.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgSnOggZ2IvaoWTXGMuT0shjvzv7eZOrKS8Lp1EZe8VKoZuqic5muC1xMApqkhx7hkecRtpqKZnuS6ip48STDoL8i1zFJ1KdXqQK9dvhNPpyuq8_pCeYcwFWxuT4pEKZgJZ4uJ7Pfg3YDUw/s1600/reports.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgSnOggZ2IvaoWTXGMuT0shjvzv7eZOrKS8Lp1EZe8VKoZuqic5muC1xMApqkhx7hkecRtpqKZnuS6ip48STDoL8i1zFJ1KdXqQK9dvhNPpyuq8_pCeYcwFWxuT4pEKZgJZ4uJ7Pfg3YDUw/s400/reports.png" width="323" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">I have found that you usually need to export bits from multiple reports and edit them in excel to create one final report with the info you want. This can be time consuming and for something simple like x,y and z points for say road edges and centreline I prefer to create points from corridor and then export these to csv file for set out. There is a report in Civil 3D that looks like it will get you this information and it does to a certain extent but it is not in a format that is easily unloadable to a GPS logger for setting out. Below is the procedure, which is by no means a one-click solution but it does the job.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">First set your corridor frequency to the chainage interval that you want setout info for. In my case every 10m.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga5hP9Lg7ykX0_HqEXUMCU5KfvWbi5wSXjUsP0MOjksEZZrq1hOI9KMBlwJ-SCbTViJDueN5TPJ_Nwm_hzgA1tLoerG2Mnx4JEE9lA6sMAwHQUvBPYPcehADFafzI-0n_FYmsjrb6Ed5SN/s1600/frequency.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="371" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga5hP9Lg7ykX0_HqEXUMCU5KfvWbi5wSXjUsP0MOjksEZZrq1hOI9KMBlwJ-SCbTViJDueN5TPJ_Nwm_hzgA1tLoerG2Mnx4JEE9lA6sMAwHQUvBPYPcehADFafzI-0n_FYmsjrb6Ed5SN/s400/frequency.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Next we will edit the assembly we are using to add Mark Points with specific codes for the points we are setting out - Road Edge Left, REL, Road Edge right, RER and Centreline, CL. Open your tool palettes (CTRL+3) and open the Civil Subassemblies and on the Generic tab browse to the Mark Point subassembly. This just inserts a point into the assembly and corridor - a point which we can give our own unique code to.</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">When you go to insert this into your assembly you can set the point code in the properties dialog box.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmDjxyMWukFLVFPHB4AayqhisBs-KIxgi-w_ObMasITo2NOyX6McudwMbXMe0Yell6l_N56mly2Xfdz7BA40stf1S5R5pFiaXoCOkcIZvmdxpc3gzKsKHNxW935jPbx-yb2-rjqilBCBEn/s1600/insert_mark_point.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="213" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmDjxyMWukFLVFPHB4AayqhisBs-KIxgi-w_ObMasITo2NOyX6McudwMbXMe0Yell6l_N56mly2Xfdz7BA40stf1S5R5pFiaXoCOkcIZvmdxpc3gzKsKHNxW935jPbx-yb2-rjqilBCBEn/s400/insert_mark_point.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Set the code and then select the relevant location in your assembly - right edge of carriageway in my example above, just click on the existing marker at the end of the lane subassembly where you want to point to be. You will probably not notice anything different happen on the assembly as it is just inserting a point. Repeat this for any other points that you want to extract from the corridor, naming the point code appropriately.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">Next select your corridor in plan and click on Launch pad on the top right of the ribbon and then select Points from Corridor and only select the codes from the Mark Point subassemblies.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFR1Ugx_MuKT2BXLjq6kMs38AoVK8vcSyttL_tNKu3nlP_T_pqLEFef7OHNUymclphuiX1Fg1frpSVbimS-Kc4nPbVqT27CGAPE7d2z4Qs1iD7SLwQlAG2FUtgfoQk1iSl_GvVHcDZlIyy/s1600/points_from_corridor.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="291" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFR1Ugx_MuKT2BXLjq6kMs38AoVK8vcSyttL_tNKu3nlP_T_pqLEFef7OHNUymclphuiX1Fg1frpSVbimS-Kc4nPbVqT27CGAPE7d2z4Qs1iD7SLwQlAG2FUtgfoQk1iSl_GvVHcDZlIyy/s400/points_from_corridor.png" width="400" /></span></a></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">This will create cogo points from the corridor at 10m intervals for each of the mark points using the point code for the cogo point description (RER, CL, REL). Next step is to separate these points into point groups based on their descriptions and export them to csv file. Create point groups for each code (RER, CL, REL) and include points related to that groups code. i.e for the point group CL only include points with description CL.</span></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Next export each of the point groups to csv - right click on the point group and export points and fill out the info in the following dialog box.</span></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">When Civil 3D creates points from corridor it does so for each string along the length of the corridor. This doesn't suit from a setting out point of view where it will probably be set out in a cross section manner rather than doing each string separately. When you export each of the point groups to excel you will need to renumber the points and then copy and paste them into one excel file to create one complete set out file. In my case I have 3 points at each chainage so I renumber all the REL points 1,4,7... CL points 2,5,8... and RER points 3,6,9.... This is easy done in excel and then copy paste into one excel file and sort by number. You now have set out points at each chainage. By no means the smoothest of workflows but it gets the job done. There are 3rd party add-ons you can get for Civil 3D that allow you to create custom report formats. I haven't explored what sort of results you get from using the Trimble add on or similar to export a corridor to a logger.</span></div>

From experience I know a lot of people aren't aware that it can be done or think that it is difficult to do. The result is that a lot of people are exporting Civil 3D models to AutoCAD and hatching manually (madness!).</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">The code set style is what is used to control the appearance of your corridor in Civil 3D. It is a pretty big style and can look intimidating at first (it controls display in plan, section and 3D views, as well as labelling). This has been the most common thing that I have been asked from users in relation to corridor appearance - how to hatch a corridor in plan. Here's my corridor before, not exactly jumping off the page:</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEivpEub0OJsoqRuXlSqVijpEDGnlJHQllGF0bYKcUNPAg72Hm9NQXJ0uh2Stv0-8U2Xk0siVmgT8ybhwMtrM5CvGEHybo-RLWh8M8vuSDA87WPoquJ3GN__HRlZ93X1f3v8eUZeZ_0lN8_x/s1600/before.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="215" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEivpEub0OJsoqRuXlSqVijpEDGnlJHQllGF0bYKcUNPAg72Hm9NQXJ0uh2Stv0-8U2Xk0siVmgT8ybhwMtrM5CvGEHybo-RLWh8M8vuSDA87WPoquJ3GN__HRlZ93X1f3v8eUZeZ_0lN8_x/s400/before.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Select your corridor and go to Corridor properties on the ribbon. On the codes tab you will see the current code set style in use (<em>3D Render Basic Plan</em> in this case), we want to create a new one as below:</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbwcDbfLsiUtGqcUf3jOpKvp4LzJreBiG1yjwjbOfv7pCDXgY-9Qkok05-Eh5upp52USL4cb9UEuajVMcr9ZQUlPenq-aji13d24O6PfDc54zf1n5-wXcG8dhpUhAGWEwpxpwq_s8kIaf5/s1600/create_new.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="211" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbwcDbfLsiUtGqcUf3jOpKvp4LzJreBiG1yjwjbOfv7pCDXgY-9Qkok05-Eh5upp52USL4cb9UEuajVMcr9ZQUlPenq-aji13d24O6PfDc54zf1n5-wXcG8dhpUhAGWEwpxpwq_s8kIaf5/s400/create_new.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Before you create the new code set style, take a minute to look at the some of the ones currently available. You will notice that the style itself is broken down into Links, Points and Shapes - see image above. These L, P & S come from the subassembly you are using. Without digging into that too much, basically the L,P & S are parts of your subassembly. Points are joined by links and shapes are bound by links in your subassemblies. See below:</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">When we want to style our corridor in a particular way it is these elements of the subassembly in the corridor that we are styling effectively. When you create a new code set style you will see that the L, P & S are empty:</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJWnlCOLJi2IzopfoVengmUDRu7s4Ffk-bqCk-gLGKnrNC-9tGpcv0xVhDuVsSizM0FUjUyuH_re36GuNYJF4snYkuiB2n-fjKqlRtbMN2V2_6ZHWDxkl-XnHXIMvdtIVZ4XXTRoD48jG3/s1600/blank.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="283" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJWnlCOLJi2IzopfoVengmUDRu7s4Ffk-bqCk-gLGKnrNC-9tGpcv0xVhDuVsSizM0FUjUyuH_re36GuNYJF4snYkuiB2n-fjKqlRtbMN2V2_6ZHWDxkl-XnHXIMvdtIVZ4XXTRoD48jG3/s400/blank.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">The quickest way to populate these to suit what is in your subassembly/corridor is to click <em>Import Codes</em> at the bottom of the dialog box and browse to your subassembly in your drawing and select it. You can then assign styles to the L,P & S, see below:</span><br />

<span style="font-family: Verdana, sans-serif;">To hatch to corridor in plan we are only interested in links, and only in the Material Area Fill Style section. I am using the UKIE drawing template and picking some of the styles from that and assigning them to particular links in my corridor. Note that the Top link is generally common to most subassemblies so applying a style to this will likely colour your corridor all the one colour so best not to use it. If you are having trouble figuring out which link you should be applying a style to then hover ('hoover' if you are Dutch! ;)) over that link in your corridor and you will find the name of it in the tooltip that appears.</span><br />

<span style="font-family: Verdana, sans-serif;">If you are not showing links in your corridor you can find the code by selecting your subassembly, right click and select properties and find the Top Link Code name as below:</span><br />

This is similar to a </span><a href="http://civilintentions.blogspot.ie/2012/07/using-civil-3d-to-convert-drawing.html"><span style="font-family: Verdana, sans-serif;">previous post</span></a><span style="font-family: Verdana, sans-serif;">, so here is a different way of doing the same thing effectively with possibly less steps.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">First open the drawing with the plots to be converted. Set the current coordinate system in the drawing by using the MAPCSASSIGN command. Then export the polygons to SDF(or SHP or whatever you wish) file format by typing MAPEXPORT. Choose the polygons/layers that you wish to export. On the Options tab you can specify a coordinate conversion as part of the export, see below:</span><br />

<span style="font-family: Verdana, sans-serif;">Now in a new drawing (with or without the second coordinate system set), type MAPIMPORT and select the file exported previously and it will import your plots to the new coordinates.</span>Donal McMorelandhttp://www.blogger.com/profile/02440880792459948241noreply@blogger.com0Slieveaun, Co.

Well as in the previous post about the Civil Infrastructure specialisation it means that by engaging with us you are tapping into Amicus' knowledge, expertise and commitment to implement and support your use of Autotrack. We have been the sole Autotrack Authorised reseller here in Ireland for the past number of years. We have been selling and training Autotrack as well as undertaking vehicle creation and trackings for customers both here in Ireland and the UK during that time.</span></em><br />

Casual users who maybe needed the software three or four times a years would previously have rented the software for a week and completed their work. Now that this option has gone under Autodesk it does not pay for them to purchase a full licence. Amicus Technology, as one of the recognised key partners, can (and have been) bridge the gap for Autotrack users by providing the vehicle creation or swept path analysis service direct to the user.</span></em><br />

It turned out to be less straight forward than initially expected. The existing road is higher than the ground around it and original had a 2:1 embankment - that is all the information provided on the original condition. The fill material was dumped on top of this embankment. No survey existed for the original embankment so we had to somehow recreate the original ground level before we could calculate the volume of dumped material.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">Belo is a screen shot of the current situation with a section through the fill to be quantified:</span><br />

<span style="font-family: Verdana, sans-serif;">What we need to do is recreate the original field levels and road embankment at 1:1 to do our volume calculations - for simplicity we are going to assume the slope of the field continues in at the same grade towards the road:</span><br />

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">To recreate the original field slope where the material was dumped we are going to use the overlaywidenmatchslope subassembly to build a corridor and get it to look at the existing field slope and continue this back in towards the road. Insertion point is toe of current slope and setting a target (green line) further out in the field will enable the assembly to calculate the slope of the field. </span></div>

<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">I would imagine this is a work in progress given the series of steps that you have to go through to import a section of the point cloud into Civil 3D, see what you think.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<strong><span style="font-family: Verdana, sans-serif;">Recap:</span></strong><br />
<span style="font-family: Verdana, sans-serif;">First of all import your raw point files into Recap, click on New Project:</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3gBGP1wwAjfm-kJARikcaIo1FTN7Kryed1LI4BEsPwnlpT1PDHrQCPZcO3YT77BYnaaw9GFKSsbczXyQwcUa4posg3B3GrgDbNH1JqK1rh-3fgTwnXSuRKAZsA6pkW0ia_YIuPJG3mwJs/s1600/new.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="186" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3gBGP1wwAjfm-kJARikcaIo1FTN7Kryed1LI4BEsPwnlpT1PDHrQCPZcO3YT77BYnaaw9GFKSsbczXyQwcUa4posg3B3GrgDbNH1JqK1rh-3fgTwnXSuRKAZsA6pkW0ia_YIuPJG3mwJs/s400/new.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Browse to your raw files and click next. You can edit the settings here to remove noise, or specify the minimum space that any one point can occupy (decimation grid).</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjj0eQL9TnqaU3fNUYBNP4gGs5nZxJog8gDl6sZZ1_ZTimdgX8Aeg41b09HVapLVVJAJVasPO-Zaolv_oAzAZ0ITmtsqgXehDNwwqOesOGyakcacGpbn1Nlsn6PUMq4mKpQ_LPASuInVC3f/s1600/browse.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="308" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjj0eQL9TnqaU3fNUYBNP4gGs5nZxJog8gDl6sZZ1_ZTimdgX8Aeg41b09HVapLVVJAJVasPO-Zaolv_oAzAZ0ITmtsqgXehDNwwqOesOGyakcacGpbn1Nlsn6PUMq4mKpQ_LPASuInVC3f/s400/browse.png" width="400" /></span></a></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">After importing the raw files, if you browse in windows explorer to the folder where the raw files were you will notice that there is now an .rcs file. This is the Recap indexed point cloud file. When you want to import the point cloud into any of the other Autodesk software packages it is this rcs file that you import.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHw9cOGdgwgOsr88BBKmaFqN6LZGxFeXzNwlCdITnwGPyh5seakb2SGvaUni5l1UprNdKbNNBUjlNr-34np6GZ7J6PvLUUg2NzMAIxGJ0Zk44WmzmF4eXNcZprkMj9byPOPsUPwZVQS0gh/s1600/rcs_file.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="266" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHw9cOGdgwgOsr88BBKmaFqN6LZGxFeXzNwlCdITnwGPyh5seakb2SGvaUni5l1UprNdKbNNBUjlNr-34np6GZ7J6PvLUUg2NzMAIxGJ0Zk44WmzmF4eXNcZprkMj9byPOPsUPwZVQS0gh/s400/rcs_file.png" width="400" /></span></a></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Once you have your point cloud in Recap the first thing that you may notice is that the point cloud doesn't appear to be as dense or as detailed as you would expect, or that there appears to be sections (strips) of points missing.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBteMH3qoHESqbJlADJabVGhv8Vf0fkW4CIuqthVu5qmM91XXcsfzNQk6eM1IlVv7aMl8SesXmT_-BQ_urtDxtKyizdVl8Mt7IOkxUepDxAivpMM3orsURs8PBmDm7-djNGAmQE3N-fYK5/s1600/poor_display.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="368" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBteMH3qoHESqbJlADJabVGhv8Vf0fkW4CIuqthVu5qmM91XXcsfzNQk6eM1IlVv7aMl8SesXmT_-BQ_urtDxtKyizdVl8Mt7IOkxUepDxAivpMM3orsURs8PBmDm7-djNGAmQE3N-fYK5/s400/poor_display.png" width="400" /></span></a></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">This is purely a visual thing, all your points are there! There are a few changes that you can make to improve the appearance....</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"></span> </div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">The points are lit from either one or two sides by default. Turning this lighting off improves appearance.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmNRT5PZAle2nsn881zPlaflk1obXdFEdI3uJmTBnU1NIAbiZCHFHrEORTTtUN8KRl32Fw79imCETLy5dcs1Dv6sj1ohBQrfMVX0Y3hmFd0WMa2pFBtyxFAMxxxNReVSe3CPBRIvIX-nZ_/s1600/lighting.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="331" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmNRT5PZAle2nsn881zPlaflk1obXdFEdI3uJmTBnU1NIAbiZCHFHrEORTTtUN8KRl32Fw79imCETLy5dcs1Dv6sj1ohBQrfMVX0Y3hmFd0WMa2pFBtyxFAMxxxNReVSe3CPBRIvIX-nZ_/s400/lighting.png" width="400" /></span></a></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Secondly you may need to adjust the point cloud origin so that it is on or near the points themselves or the area of interest.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjthfwza8v7nVN43GAG3aRY5_CNBAg-OXffsQsRvPY1PhmvoJl_8RSqatYw6XVTxKWpUtBL_u0qHvFGOAHt3su5tWqvP8OucESnYHLX93OGk3XCb7hHiM2641z8yGKaF-26bTgFa-ccBhvZ/s1600/origin.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="227" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjthfwza8v7nVN43GAG3aRY5_CNBAg-OXffsQsRvPY1PhmvoJl_8RSqatYw6XVTxKWpUtBL_u0qHvFGOAHt3su5tWqvP8OucESnYHLX93OGk3XCb7hHiM2641z8yGKaF-26bTgFa-ccBhvZ/s400/origin.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">Follow the prompts on the screen. For this example I chose a point on the road surface and pressed the TAB key to flip the axis so that the 'Z' axis was in the correct direction.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8RIXoyHfX8IXSFLCL-OKAGY7BGiwcl_hvOWre4FypyPZZpWFcYFCMlQULsMpAqN_yLtSwC8QsXZKKtlhM0OZhnQRoSb-OoAuDgcl2X8zAGVww5QVOKsOUuJUtkrQunqekUjTKOUYQgpgu/s1600/z_axis.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="323" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8RIXoyHfX8IXSFLCL-OKAGY7BGiwcl_hvOWre4FypyPZZpWFcYFCMlQULsMpAqN_yLtSwC8QsXZKKtlhM0OZhnQRoSb-OoAuDgcl2X8zAGVww5QVOKsOUuJUtkrQunqekUjTKOUYQgpgu/s400/z_axis.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">You can also reduce the point size which will also impact appearance.</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh1zINzGou2034vVTrrf3AjkzCDanTpaTp3YMQnrwgef3vKEta0nTR0wxlb_XNuljbu5PPW26Dg-XekFxKBBsLFuD5j3_UdSeS8kzjMdzh__suuIPAfQ_RpzZTS8RDB721aj_LVXGf9AJZJ/s1600/point_size.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="371" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh1zINzGou2034vVTrrf3AjkzCDanTpaTp3YMQnrwgef3vKEta0nTR0wxlb_XNuljbu5PPW26Dg-XekFxKBBsLFuD5j3_UdSeS8kzjMdzh__suuIPAfQ_RpzZTS8RDB721aj_LVXGf9AJZJ/s400/point_size.png" width="400" /></span></a></div>
<span style="font-family: Verdana, sans-serif;">The result will be a much clearer looking point cloud:</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">The next thing we need to do is to clip out the portion of the point cloud we wish to import into Civil 3D. I am going to clip out a section of the road and then edit this to remove any points that I do not need, such as the trees you see on the left in the screen shot above.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">Use the window or fence select tool to highlight the area you wish to keep...</span><br />

<span style="font-family: Verdana, sans-serif;">Once you have tidied up your section of interest it is important to point out here that the edits you are making are not saved back to the rcs file. The only way I have found of being able to effectively save these changes to an rcs file is to export the points to a raw point file format first and then reimport them back into Recap so that it creates a new rcs file. To do this click on export first...</span><br />

<span style="font-family: Verdana, sans-serif;">All of the above amounts to a pretty long winded workflow to create a surface from a point cloud in Civil 3D. It works well but there is room for improvement, for example when you trim the point cloud in Recap you should be able to save this out as an edited rcs file without the extra export/reimport steps. </span></div>

It appears that people are requesting PDF or paper hard copies of the folios, importing them into their CAD package, positioning and tracing over them, adding their own info and resubmitting them to the PRA.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">This is a very slow process and an unnecessary one too! You can request folio information in digital format and import this straight into the likes of Civil 3D or Map 3D. Request the folios in shape (SHP) file format. There may be an initial search cost but after that the cost is the same per folio as for the paper or PDF format... except you don't have to do all the tedious positioning and digitising in CAD.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">To import the shape files use the following workflow (just change files of type to shp):</span><br />

<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana, sans-serif;">This post on Storm & Sanitary Analysis (SSA) makes use of the Modified Rational Method (Wallingford Procedure) and applies only to users in Ireland, the UK and anywhere else that uses this method.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">SSA itself was originally called StormNET which was developed by a US based company called BOSS International. Autodesk purchased this package from BOSS about 3 years ago and included it with Civil 3D as an additional download in 2011 and as part of the main installation in subsequent years. Apparently it is a very comprehensive piece of software that sells for about $1100 per seat starting price on its own in the US.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">Given that a different method of hydrologic analysis is used in this part of the world than in the US a lot of the functionality in the software is unusable here. When Autodesk purchased SSA some customisation for the Irish & UK market was undertaken which opened up a certain amount of the software's capability to users here. This post will cover what those functions are and also (some of) the limitations.</span><br />
<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana;">When you select Modified Rational Method as the hydrology type in SSA you can:</span><br />
<ul>
<li><span style="font-family: Verdana;">Calculate Greenfield runoff rate for the site (can use the catchment info imported with your pipe network from C3D).</span></li>
<li><span style="font-family: Verdana;">Based on the greenfield runoff rate you can calculate the SUDS storage volume required.</span></li>
<li><span style="font-family: Verdana;">You can run a storm event through your network and get SSA to upsize the pipes if necessary.</span></li>
<li><span style="font-family: Verdana;">You can specify a storm event to check for surcharging in the pipes.</span></li>
<li><span style="font-family: Verdana;">You can run analysis for circular pipes only (no open channels).</span></li>
</ul>
<span style="font-family: Verdana;">In the context of the analysis type discussed in this post (capacity check) it will tell you if a pipe is surcharged. What it doesn't tell you is if the extra flow could be accommodated for by storage in the structures. Since it can't calculate for storage in the structures it also can't determine if there is ponding at the structures. </span><span style="font-family: Verdana;">This is a serious limitation when it comes to this type of analysis.</span><br />
<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana;">So where is the software headed? Are we likely to see this functionality added for the modified rational method (MRM)? (the software can calculate for storage at the structures and ponding for the other hydrology methods as well as a whole array of other drainage design requirements just not for modified rational). It is hard to say whether this functionality of the software will be modified and opened up or here. There hasn't been any extra development in the software for the MRM for the last two releases (2013 & 2014). That would indicate that development has been put on hold so your guess is as good mine where it is heading. It is an obvious hole in the Infrastructure Design Suites offering at present. I imagine part of the plan of moving to suites rather than standalone products is so that Autodesk can offer a full design workflow and not have to provide export/import compatibility to third party software such as WinDes. I would think that given such a small market use the MRM the development of SSA to accommodate this is not too high up the priority list at Autodesk. Especially since it provides full functionality for other regions. Maybe if someone from Autodesk is reading this they can give some insight to what the future holds....</span><br />
<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana;">That said what it does, it does well and is easy to use. The fact that you can essentially do your 3D pipe network drafting in C3D and then export this to SSA ready for analysis makes for a smooth workflow. My own feeling is that if you are currently using an excel sheet for drainage design then you will save yourself hours and probably days of manual effort transferring invert levels and pipe sizes from excel to CAD and drafting up the result - especially when changes occur. (once the analysis is complete in SSA you can export back to C3D and it will update your pipe network for you - in plan and profile). I have spent my fair share of time designing pipe networks using excel sheets to know what is to be gained using C3D and SSA. Those excel sheets to be fair also probably contained errors given how many times they were handed down inside in an office but that is a different matter! If you are currently using WinDes with all the bells and whistles then this isn't going to be up to scratch - but those bells and whistles are expensive! For those who are using WinDes I would also consider using C3D as your pipe network drafting tool. You can lay out and display pipe networks both in plan and profile as well as extract setting out info and tables extremely fast once you have got your head around the commands. There is an export to WinDes tool to send the pipe network out for analysis and import from WinDes tool to bring back in the results. </span><span style="font-family: Verdana;">Hopefully we will see some future development from Autodesk for this part of the world!</span><br />
<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana;">Next post we will run through a workflow to complete the sewer capacity check in SSA...</span>Donal McMorelandhttp://www.blogger.com/profile/02440880792459948241noreply@blogger.com2Clarinbridge, Co.

<span style="font-family: Verdana, sans-serif;"></span><br />
<strong><span style="font-family: Verdana, sans-serif;">Creating Catchments</span></strong><br />
<span style="font-family: Verdana, sans-serif;">Before we export our pipe network to SSA for analysis we need to define our catchments.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">You can do this by first creating polylines to define each catchment. Follow the approach outlined in the previous post of using the surface slope arrows and the kerb lines to determine what sections of surface drain to each structure. Once you have polylines drawn you can turn them into catchments</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">In the Prospector tab of Toolspace right click on Catchments and select Create Catchment Group. Then right click on the catchment group and select Create Catchment from Object. Select a polyline and press enter to skip the flow path option. In the dialog box that follows we need to set four things:</span><br />
<ol>
<li><span style="font-family: Verdana, sans-serif;">The catchment name - call this the same as the structure the catchment will flow to.</span></li>
<li><span style="font-family: Verdana, sans-serif;">The reference structure - use the box to the right to select structure from the drawing.</span></li>
<li><span style="font-family: Verdana, sans-serif;">The runoff coefficient - depends on the type of ground and will differ for the region or standard you are designing for but generally 0.9 for hard surfaces.</span></li>

<span style="font-family: Verdana, sans-serif;">This post follows on from the <a href="http://civilintentions.blogspot.ie/2013/07/sewer-network-capacity-analysis-part-1.html">previous one</a> on drawing setup</span></div>
<div class="separator" style="clear: both;">
<b><span style="font-family: Verdana, sans-serif;"><br /></span></b></div>
<div class="separator" style="clear: both;">
<b><span style="font-family: Verdana, sans-serif;">Create Pipe Network</span></b></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">After the initial setup it is time to create your pipe network. There are two main options.</span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">1. Create Pipe Network from Objects. This is usually a better choice for proposed networks where you may have drawn the initial pipe layout using a series of connected polylines. For a survey like this each pipe run will typically be a single polyline. When you use this command it will allow you only to select one object so you would end up with multiple (many, many multiple) pipe networks that would need to be merged together at the end into a complete network. This is a pain and it is best avoided.</span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">2. Pipe Network Creation Tools. This opens up the pipes toolbar and will allow creation of multiple parts. You select the pipe and structure type and size and then start tracing over the survey polylines. This is a better option.When you are prompted, give your network a name and set the parts list. Do not set a reference surface as we do not want elements to try and correct themselves based on any surface information later.</span></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><b>What to Include in your Existing Network</b></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">Initially you may plan on recreating all elements of the surveyed network using C3D pipes. This is most likely unnecessary and will probably cause you problems. See below:</span></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Verdana, sans-serif;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjaQuYMmHRH7HNxoBDbtAwDTSCFyt_jh1LsoOEIx-4L8jD24YB5HPCjvQ1xXfaRpn1pJNmKfgKA_wT6mVNf_BpQJT5O3JFaKShJlqQWZL-GYy1FRbDTdksjQbidCpbiGpKJSAHqSGVX5qKY/s1293/gully_connections.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="252" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjaQuYMmHRH7HNxoBDbtAwDTSCFyt_jh1LsoOEIx-4L8jD24YB5HPCjvQ1xXfaRpn1pJNmKfgKA_wT6mVNf_BpQJT5O3JFaKShJlqQWZL-GYy1FRbDTdksjQbidCpbiGpKJSAHqSGVX5qKY/s400/gully_connections.png" width="400" /></a></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">Based on the surface slope arrows and also the layout of the kerbs and gullies I can determine the catchment for a particular structure (Blue Polyline). This structure has 6 gully connections all of which feed from the same catchment. The total flow for the catchment is assigned to the structure and it is not necessary to subdivide the catchment into flow for each gully. Therefore there is no benefit to modelling gully connections as C3D pipes. This will reduce the number of pipes and structures in your network.</span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;"><b>Drafting the Pipe Network</b></span></div>
<div class="separator" style="clear: both;">
<span style="font-family: Verdana, sans-serif;">The plan here is to use the pipes toolbar to trace over the main elements in your network and recreate the pipes and structures. We will forget about invert levels and cover levels when laying out the network and return to these afterwards.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Verdana, sans-serif;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjluTl5luy6wg_BWpcHrJNMx2A9QKYZBkeOEJ5FTcMR7cKQrBtGdDqk5pGCLt39jt59aB-qhj8-Ds18DdfvXevUGE7Sq6aOoYjjCS0Ll0sKImaMjNQI3Ts963JE1hffmshMiGSY-apTX_PU/s652/draft_network.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="296" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjluTl5luy6wg_BWpcHrJNMx2A9QKYZBkeOEJ5FTcMR7cKQrBtGdDqk5pGCLt39jt59aB-qhj8-Ds18DdfvXevUGE7Sq6aOoYjjCS0Ll0sKImaMjNQI3Ts963JE1hffmshMiGSY-apTX_PU/s400/draft_network.png" width="400" /></a></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Use the pipes and structures command above, start to layout your network by clicking at each structure location. The default drafting direction will be downstream so try to work this way - otherwise you may get warnings when you try to analyse in SSA later.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"><b>Editing Invert & Cover Levels</b></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Once you have recreated the main elements of your network we can then inspect the survey elements to determine the actual invert & cover levels of the pipes and structures and apply these to our network elements.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">There are two main ways of getting this info from the survey elements:</span></div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<ol>
<li><span style="font-family: Verdana, sans-serif;">Use the 'ID' command (type at command line) and click on the ends of the pipe polylines to get invert levels.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Use the text at the structures to determine cover and invert.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ2mecO1x8yv1Q-AUAgkUr3pzGq0H0eSjdWON_arqRvAIc9YLfJByCM9wmneMJwLzptLfRYAoBzPHKkLaIQFdOUPDNVuuYuwAsZbpQoBVnUJRmAk4cZI9Zm1oNH19909fBqgWqP8NiWUB5/s1134/id_structures.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" height="270" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ2mecO1x8yv1Q-AUAgkUr3pzGq0H0eSjdWON_arqRvAIc9YLfJByCM9wmneMJwLzptLfRYAoBzPHKkLaIQFdOUPDNVuuYuwAsZbpQoBVnUJRmAk4cZI9Zm1oNH19909fBqgWqP8NiWUB5/s400/id_structures.png" width="400" /></a></span></li>
</ol>
<span style="font-family: Verdana, sans-serif;">Using ID for each polyline is the most thorough and accurate approach. An (quicker and less accurate) alternative is to use the invert level of the structures as the invert level of the incoming and outgoing pipes - and assume they are they same. This is a lot quicker and may not make that much difference to the overall capacity analysis. Whatever approach you decide to use you will need to make note of the invert levels of the pipes and structures and then apply these to the C3D elements.<br />
</span><br />
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<span style="font-family: Verdana, sans-serif;">
</span>
<br />
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">The best way to manually add this info is to select a structure and click on Structure Properties on the ribbon. On the Connected Parts tab you can edit the invert levels of the incoming and outgoing pipes first.</span></div>
<span style="font-family: Verdana, sans-serif;">
</span>
<br />
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Verdana, sans-serif;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdSXVN-Gd3lYEVHrCihOznj8jrC4Y0Mn6XAuQBRy3xHEV2-GySq9rkMhjf2EO6IWSruIIj9ltNbokNSRc7IT3fG65jP8IsN9b8HhbM6GFIT6jvNGvrWxZ6nGjDCJ3PmsKv0Bsyen8oW76Z/s969/connected_parts.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="256" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdSXVN-Gd3lYEVHrCihOznj8jrC4Y0Mn6XAuQBRy3xHEV2-GySq9rkMhjf2EO6IWSruIIj9ltNbokNSRc7IT3fG65jP8IsN9b8HhbM6GFIT6jvNGvrWxZ6nGjDCJ3PmsKv0Bsyen8oW76Z/s400/connected_parts.png" width="400" /></a></span></div>
<span style="font-family: Verdana, sans-serif;">
</span>
<br />
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Next move to the Part Properties tab and set the Automatic Surface Adjustment to False - you can then enter the cover level (Rim elevation). Set the Control Sump Depth By property to Elevation and enter the structure invert level (Sump Elevation).</span></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Verdana, sans-serif;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCSRxZcT4IJm3ZgrDoN4H9OMDfyzlZzeUaQYzprBuQUdsZXZnFKMYm1wKkn3EOWoVYo8zwFYABCJZB8rg_sWyE0V2RpzK311jnQCmOeRWbkf4Px8p_Bnxv7ErsDEuOZi_QaajwbMNcZvLM/s668/part_properties.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="193" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCSRxZcT4IJm3ZgrDoN4H9OMDfyzlZzeUaQYzprBuQUdsZXZnFKMYm1wKkn3EOWoVYo8zwFYABCJZB8rg_sWyE0V2RpzK311jnQCmOeRWbkf4Px8p_Bnxv7ErsDEuOZi_QaajwbMNcZvLM/s400/part_properties.png" width="400" /></a></span></div>
<br />
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">Click Apply and ensure that the values you enter hold. If they change then check to make sure that the structure invert level isn't higher then the lowest connected pipe invert. If this is ok then maybe look at the type of structure you are using. Sometimes there will be minimum dimensions for the structure elements and these may affect the manually entered invert levels - an you may need to use a different structure type.</span></div>
<span style="font-family: Verdana, sans-serif;">
</span><br />
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<span style="font-family: Verdana, sans-serif;">
</span><div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Verdana, sans-serif;">This process is repeated for the entire network. It is important to ensure that you have the network as correct as possible at this stage before you export to SSA or you will be presented with a series of errors when you run the analysis.</span></div>
<span style="font-family: Verdana, sans-serif;">
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Common things to look out for are that the correct number of pipes are connected to a structure and that they are sloping the correct way.</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib6J4pefatyL2UYOySbQadJEscP6pFNCrvxRUmOj-EeSsKC6WTBsQGGnNyHHjGmjfB2HvvCa-9v5QhmuqBDWpkghPoLrIcVPDwxntP4z_aTWH74FYBdJGSoQLibUM4yuUGU5CiunmvytpM/s785/struct_prop.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="208" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib6J4pefatyL2UYOySbQadJEscP6pFNCrvxRUmOj-EeSsKC6WTBsQGGnNyHHjGmjfB2HvvCa-9v5QhmuqBDWpkghPoLrIcVPDwxntP4z_aTWH74FYBdJGSoQLibUM4yuUGU5CiunmvytpM/s400/struct_prop.png" width="400" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
In the connected parts tab you can identify what pipes are coming into a structure (should be IN and have positive slope) and those which are going out (should be OUT and have negative slope. If these look wrong then check invert levels before exporting.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Another common issue at this stage is that a pipe is not connected to a structure. It may look like it is connected in plan but if it is not listed on the Connected Parts tab then it is not connected. You can fix this by selecting the pipe in plan and choose Connect Part on the ribbon and select the structure to connect.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
If a pipe or structure is the incorrect type or size you can select it, right click and choose swap part and choose the correct one.</div>

The SSA part will apply to users in Ireland and the UK only (or anywhere else that uses the modified rational method as the hydrology method).</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><b>Project Background</b></span><br />
<span style="font-family: Verdana, sans-serif;">The survey consists of an AutoCAD drawing containing 3D polylines (pipe inverts) and blocks and text for manholes and data. Features such as kerbs, roads, banks etc are also included so a ground model can be generated.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>

<span style="font-family: Verdana, sans-serif;">There is a proposed new building for the greenfield area to the east of the existing building. It is proposed to connect the storm network from this proposed building into the existing network. The sewer capacity analysis is required to check first if the existing network can take the current flows and if so what capacity remains in the network and can it accommodate the new flows.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;">The survey drawing for the underground utilities will usually be 'crowded' - see below:</span><br />

<span style="font-family: Verdana, sans-serif;">In this case we are only interested in the storm elements so this drawing can be made a lot simpler, see below.</span><br />
<span style="font-family: Verdana, sans-serif;"><br /></span>
<span style="font-family: Verdana, sans-serif;"><b>Initial Drawing Setup</b></span><br />
<br />
<span style="font-family: Verdana, sans-serif;">Generally the best first step is to copy and paste everything from your survey drawing into your C3D template - in my case I am using the <i>AutoCAD Civil 3D UKIE.dwt</i>.</span><br />
<div>
<span style="font-family: Verdana, sans-serif;"><br />Create your ground model from the survey drawing - see the following <a href="http://civilintentions.blogspot.ie/2012/12/creating-3d-ground-model-from-autocad.html">post</a> if you are creating from CAD elements.</span></div>
<div>
<span style="font-family: Verdana, sans-serif;"><br />Isolate only the objects you need - so in this case I need anything to do with the storm network - pipes, manholes, text, gullies etc. Also isolate objects that affect the flow of water on the ground (kerb lines, buidlings etc) so we can determine catchments for the network. The drawing will be a lot simpler to read.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgP_pDF3tPJxCHMYRlfUsFjeMbjsTOqLu-ruqwzqbyB7jpTruM4b6p8VlyBNVF0R5e4z898Zr90xpzlRN0ZupthCQVaozm5aZc1pEwDlUcthbEyxYxRIyZT_QaFbqhfTEejDGUVU7KBZa6b/s778/isolated_network.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="281" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgP_pDF3tPJxCHMYRlfUsFjeMbjsTOqLu-ruqwzqbyB7jpTruM4b6p8VlyBNVF0R5e4z898Zr90xpzlRN0ZupthCQVaozm5aZc1pEwDlUcthbEyxYxRIyZT_QaFbqhfTEejDGUVU7KBZa6b/s400/isolated_network.png" width="400" /></a></span></div>
<div>
<b><span style="font-family: Verdana, sans-serif;"><br /></span></b>
<b><span style="font-family: Verdana, sans-serif;">Set Pipe & Structure Catalog</span></b></div>
<div>
<span style="font-family: Verdana, sans-serif;">Next set the pipe and structure catalog to your localised settings. The catalogs are the highest level library of pipes and structures and contain all the elements that you can use in the drawing.<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjpeWYBGFHCuAVur8kcqeuRt_v-FH2Lidjj0wQB_P4FAt1iOwdItcBy1Vjzn5NgT-irWgEiJYLuHMZAUxbqmhVHTgUuk2rJN_kiBO9TXIAysQhDNflAkTKKF8MVgwMfC66EEWj1dlDILGYM/s713/set_catalog.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" height="245" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjpeWYBGFHCuAVur8kcqeuRt_v-FH2Lidjj0wQB_P4FAt1iOwdItcBy1Vjzn5NgT-irWgEiJYLuHMZAUxbqmhVHTgUuk2rJN_kiBO9TXIAysQhDNflAkTKKF8MVgwMfC66EEWj1dlDILGYM/s400/set_catalog.png" width="400" /></a></span></div>
<div>
<b><span style="font-family: Verdana, sans-serif;"><br /></span></b>
<b><span style="font-family: Verdana, sans-serif;">Create a Parts List</span></b></div>
<div>
<span style="font-family: Verdana, sans-serif;">Next create a Parts List - this is a subset of the higher level catalog and will generally contain only the pipes and structures required for a particular type of network - eg Storm, Foul, Electrical ducting, water network etc. To create a parts list go to the Settings Tab of Toolspace and expand the Pipe Networks section. Right Click on Parts Lists and select Create Parts List. Give you Parts List a name.<br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmsGrgLo9yFH3YhkMXHsHZMt8UakEpCIlRJMLbr3wzIgpT31nvsTvq90vF8ou9yB45Xuu6wXrVoZ4WmOxCYArTYQP8IUdy5cK6SPuOeoeOANo_FO6CD3QWEXpLFd9KiC7zpzIEqCG66qfp/s568/create_parts_list.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="296" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgmsGrgLo9yFH3YhkMXHsHZMt8UakEpCIlRJMLbr3wzIgpT31nvsTvq90vF8ou9yB45Xuu6wXrVoZ4WmOxCYArTYQP8IUdy5cK6SPuOeoeOANo_FO6CD3QWEXpLFd9KiC7zpzIEqCG66qfp/s400/create_parts_list.png" width="400" /></a></span></div>
<div>
<span style="font-family: Verdana, sans-serif;"><br /></span></div>
<div>
<b><span style="font-family: Verdana, sans-serif;">Add Part Families & Sizes</span></b></div>
<div>
<span style="font-family: Verdana, sans-serif;">The new parts list will initially be empty. We need to add in the pipe and structure types and sizes for our network. Still in the Create Parts List dialog box, browse to the Pipes tab. Right click on your network name and select 'add part family'.</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">Once added then right click on the family and choose 'add part size' Tick the sizes you need or the box to add all sizes.</span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Verdana, sans-serif;">Repeat these steps on the structures tab for the types and sizes you require.<br /><br /><b>Assign Rules & Styles</b><br />Apart from creating a smaller more manageable set of pipes and structures the other main use of the parts list is to assign styles (for plan, profile, section) and rules to your pipes.</span></div>
<div>
<span style="font-family: Verdana, sans-serif;"><br />The rules are more useful when laying out a proposed network and for this type of work we do not want to apply any rules. You can't turn rules off but you can create your own set of 'empty' rules. Still in the same dialog box click on the button to assign Rules and then create a new rule set. Do not add any rules and call the set something like _NO RULES.</span><br />

<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">The background to the workflow is that a section of motorway requires repaving. The repaved section is designed in C3D and is already complete. The design requires that there is adequate vehicle clearance after the section of the road has been repaved. There are a number of overpasses along the motorway which have been surveyed using laser scanners. The workflow in the video demonstrates how to use Autodesk Recap, AutoCAD Civil 3D and Navisworks Manage to perform a clash detection between the clearance envelope and the laser scan data to check for adequate clearance.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">The dataset is from the Netherlands so thanks to Peter Ingles of Autodesk for putting it together!</span><br />
<span style="font-family: Verdana;"></span><br />
<span style="font-family: Verdana, sans-serif;">Please make sure that the quality settings are set to the maximum in Youtube when viewing (see small cog/gear symbol in bottom right of screen).</span><br />

<span style="font-family: Verdana, sans-serif;"> </span><br />
<span style="font-family: Verdana, sans-serif;">The issue is that for a watermain survey you may typically have only a single line of GPS points surveyed. How do you create a profile of the pipe route in Civil 3D? Well that is easy, of course it is, there is a create profile from file option in Civil 3D that will do it for me. Not so fast... the point file you have from your GPS logger will probably be in the format PENZ (point number, easting, northing, elevation). The create profile from file command requires a .txt file with two sets of values - chainage and elevation separated by spaces. To convert typical GPS survey points from coordinates into chainage is a long winded process but is possible using Civil 3D and Excel.</span><br />
<span style="font-family: Verdana, sans-serif;"> </span><br />
<strong><u><span style="font-family: Verdana, sans-serif;">There is an Alternative</span></u></strong><br />
<span style="font-family: Verdana, sans-serif;">If you create a surface from the single line of points it will not triangulate properly and you wont be able to pull a sensible looking profile along the entire pipe route. As a way of getting around this you can create dummy levels to allow you to create a proper surface and then create your profile along the route. You can do this by joining the points using a featureline and then offset this line left and right by a nominal amount, then create a surface from them. The steps are as follows (there is a video at the bottom with me narrating, Morgan Freeman wasn't available):</span><br />
<ol>
<li><span style="font-family: Verdana, sans-serif;">Import your points into Civil 3D.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Join the points using a 2D polyline (a quick tip here is to use the transparent commands. When you start the polyline command and it asks you for the first point type <strong><em>'PN</em></strong> and press enter and then type the point numbers you wish to draw the lines between. eg to join between point 1 & 100 type <strong><em>1-100</em></strong> and press enter. This will join up the points in one quick step).</span></li>
<li><span style="font-family: Verdana, sans-serif;">Use the create alignment from object command and select the polyline to create an alignment along the pipe route - we need this to create our profile.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Repeat step 2 except create a 3D polyline using the 3DPOLY command. You can use the quick tip again.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Use the Create Featureline from Objects command to create a featureline from the 3D Polyline. Untick the box to assign elevations when the create featurelines dialog appears.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Select the Featureline after you have it created and click on Edit Geometry on the ribbon. Click on the button for Stepped Offset and enter 1mm for the offset distance, select the offset side and enter zero for the level difference. Repeat for the other side.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Select the 3 featurelines and choose Add to Surface as Breakline on the ribbon. Create a surface if not already done so and accept the defaults.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Select your alignment created in Step 3 and choose Surface Profile on the ribbon. You should now see your surface and be able to create a profile as usual.</span></li>
</ol>
<span style="font-family: Verdana, sans-serif;">There is a video of the workflow at the following link:</span><br />
<span style="font-family: Verdana;"></span><br />

<span style="font-family: Verdana, sans-serif;"> </span><br />
<span style="font-family: Verdana, sans-serif;">For anyone who might be interested in doing this using the other method mentioned above, the workflow to convert point coordinates to chainage is as follows:</span><br />
<ol>
<li><span style="font-family: Verdana, sans-serif;">Follow steps 1 to 5 above.</span></li>
<li><span style="font-family: Verdana, sans-serif;">Select the featureline and click on Edit Levels on the ribbon. Open the Elevation Editor and right click on the values and select Copy All:</span><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzJWjkIOc4F_k_-GAt6RfjH1Cl_P_sHU3GrqMJ8qxlm_ylSzuAniMpwxn04sRzop9qeGu2CJiwQZSgkSxw-uKTKU1tfairk5W95lcBb6esub4aGGkUpREoUlFs2RRB3__LRLhRcI9qTzly/s1600/featureline_elevations.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Verdana, sans-serif;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzJWjkIOc4F_k_-GAt6RfjH1Cl_P_sHU3GrqMJ8qxlm_ylSzuAniMpwxn04sRzop9qeGu2CJiwQZSgkSxw-uKTKU1tfairk5W95lcBb6esub4aGGkUpREoUlFs2RRB3__LRLhRcI9qTzly/s400/featureline_elevations.png" width="400" /></span></a></li>
<li><span style="font-family: Verdana, sans-serif;">Paste the values to excel and delete the columns you don't need (we only need chainage and level columns)</span></li>
<li><span style="font-family: Verdana, sans-serif;">Save as a csv file and open in Notepad. Use the Replace command (under Edit menu) to replace all the commas with a space. Save as .txt file.</span></li>
<li><span style="font-family: Verdana, sans-serif;">In Civil 3D use the Create Profile from File command and select the txt file and this will give you the profile.</span></li>

<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">The basic workflow is to create 3D linework (featurelines) to define the outline of the pitches, applying the proposed levels at the corners as we create them. The grading of the pitches was at either 1/100 or 1/140 and we can apply this as we create the featurelines, grading tools weren't required. The boundary featureline is created by snapping to the existing ground surface along the site boundary line. (you can quickly do this by turning the boundary polyline into a featureline and get it to pick up the levels from the existing surface). We then simply added all these featurelines into a new surface to create our proposed surface.</span><br />
<span style="font-family: Verdana, sans-serif;"></span><br />
<span style="font-family: Verdana, sans-serif;">The volumes were then balanced by raising or lowering the featurelines as necessary, keeping an eye on the numbers in the volumes dashboard until they are close.</span><br />
