Sometimes I am working on a project that requires multiple FG/SG surfaces. For instance, if there are multiple phases to the project (So Phase 1 elevations will differ from Phase 2 elevations). Currently, I have to use a work around of either:
a) Creating multiple project files for the multiple surfaces and then importing them into the original project file if I want to compare
b) For the 2nd or 3rd FG surface I have to do the SG offsets manually by either offsetting the points or FG surface, having to separate the data for the varying makeups across the site.
This is a bit of a pain, and it would be nice if it were possible to simply create multiple FG/SG takeoff categories/surfaces within the original project file.
