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...
