[GRASSLIST:10532] Re: Dxf and other 3d objects in NVIZ

[Nick Cahill]

I also tried for some time to get 3d shapes from a CAD file into  
GRASS as 3d vectors. I used lots of different methods - extruded  
shapes (like v.extrude but in CAD), individual faces/surfaces, etc.,  
and never had anything come out right in GRASS. I was using v.in.ogr  
to import Microstation .dgn files - which works fine for 2d vectors,  
and for 2 1/2d vectors -- contour lines with elevation -- but not for  
proper 3d objects.
