Pre-configure Survey Database Settings

I was training some users recently on the survey side of Civil 3D and was showing them how to create a survey database and edit the survey database settings. In the company there would be a number of teams surveying each day on a number of different jobs and a team of processors in the office on the CAD end. There would be multiple survey databases created by the processors each day. A question that arose was how they might ensure that each processor would enter the correct survey database settings, could you pre configure the database settings so that you didn't have to rely on the user entering them each time? I am unaware if you can do this from within Civil 3D but it is possible to do it through Windows explorer...

When you create a survey database in Civil 3D it is stored outside of the drawing and is effectively a folder in Windows that contains the settings and survey data. We can use this to create a 'default' survey database with the required settings and then before each new survey is imported, create a copy of this folder in Windows and rename it. It will then appear on the survey tab in Civil 3D.

First set your working folder in C3D - this is the location where your survey databases will be stored.
Hover you cursor over Survey Databases and you will see the path to the working folder.

Next create your 'default' survey database with the necessary settings. In my case I am going to create two 'default' databases...

...each with different coordinate systems and set to apply scale factor on import along with a number of other settings.
Now browse in Windows Explorer to the location of the working folder. You will see folders for each of the survey databases created in C3D. Before you import survey data in C3D you can create your survey database here by copying and editing the 'default' database to suit the job you are working on:

...and renamed to Cladd Reach in this case. You will need to close Civil 3D in order to be able to copy and edit the survey database folders.
Reopen Civil 3D and on the survey tab of toolspace now you will see the new database. To use it right click on it and open for edit.
Right click on the database and click on edit database settings to see that the default settings are already configured...
