Just registered so a newbie. If out of line then please accept apologies.
I'm not an LDT user just plain Autocad and map3d. I'm here looking for ideas for batch processing of many polygons for volumes of each.
Try quicksurf/surfmate from schreiber as a 30 day trial or even better.......
If undecided, download from MicroSurvey for a 30 day trial. The full 3dmodelling/volumetric/design capabilities are available.
