Hi all.
Does anybody know whether it is possible to work (import-export) with 3D
shapefiles, with gass or other free software?
Thanks.

I made such experience, that GRASS is able to import 3D shapefiles and other
formats via OGR.
Any software, which uses OGR should do that. See

Funny - I tried the same yesterday.
Generally yes for GRASS 6:
Note: import into any location (e.g., Spearfish sample location)
################ 3D DXF/DWG example
#Example: 3D DXF from http://www.3dcafe.com/asp/architex.asp#DXF
v.in.dwg -z in=dxf/WATRTOWR.DXF out=watertower
v.info watertower
...
| Map is 3D: 1
| N: 584.584 S: -599.734
| E: 579.789 W: -584.248
| B: -1873.830 T: 594.000
...
# -> unprojected DXF (use v.transform to geocode it)
g.region vect=watertower res=10 -pa
#take B (bottom) as minimum elevation:
r.mapcalc "plane=-1873.830"
r.colors plane col=gyr
#look at it:
nviz plane vect=watertower
#Result, something like this:

3D SHAPE: If PolygonZ is properly used it should
work as well (v.in.ogr). Currently I don't have
and true 3D SHAPE file to try.
