I have a finished grade surface, is there a way that I can create a copy of the entire surface, but offset 2' below finish grade? I know it was easy in Terramodel, is it easy in TBC?
This is how I did it in Ver 4.12
1) Export out the FG surface as a .DWG
2) Import the surface.dwg
3) Convert the 3D faces to linestrings
4) Run the Change Elevation- Select all the linestings and lower them by -2'
5) Create new surface from the linestrings.
Ver 5 has a macro for copying a surface and offsetting it.
Hope this helps!
Mike, I've done a similar procedure except I don't do your step 3. Is there a reason to do the conversion to linestrings first? Also it will be nice to have the macro in v5.
You can also export as a TTM and then as you reimport it you can explode it if using the Import command vs Drag and Drop - this does the same thing. The v5 Macro will be the way to go once v5 is released.
