AutoCAD Civil3D 2015 – Map3D functions not Working

AutoCAD Map3D functions not working

If you have found that a couple of your Map3D functions aren’t working e.g. MAPTRIM, MAPINSERT, you will need to add a support path in the Options-File Tab-Support File Search Path.

In Options > Files > Support File Search Path, Add the path :

C:\program files\autodesk\autocad 2015\map\support\en-us

Apply and close the dialog box.

Now, close Civil 3D 2015 and restart it.
I believe this should now work.

Type in the 2 commands above to see if the display boxes for those functions actually show up. Once that has been confirmed your Map3D should be right to use as expected.
