Hello,
I'm just starting with vector handling in grass, but I don't understand everything correctly.
Is ist possible to display a 3d linevector, which was imported from a shapefile in NVIZ?
My vect is called "cave" and I have also a dbf table called "cave". In the table several columns are available but I think I have to link somehow the col "DXF_ELEVAT" which contains elevation data to my vector. But I'm lost.
I hope anybody can give me a hint what I have to do next.
Regards
Wolfgang

Sorry, it took me so long time.
Yes NVIZ is able to display your 3D-Vektor line. But I do not realy
understand your problem.
If your shape-file is allready 3D, you have to import it via v.in.ogr
using the -z flag
v.in.ogr dsn=./cave.shp out=cave -z
Or are your data looking different?

Hello,
problem is already solved. The converter I used to create the shp worked only in 2d! With an other converter I really get a 3d shp and that can be displayed in nviz.
Sorry for confusing you!

As far as i have understand, you got a 3d dxf... try to import with v.in.dxf
in current cvs version

Hello Luca,
you are right, I have a 3D dxf but I'm not that experienced that I dare to compile grass on my own (cygwin on xp). It seems to be more easy on a native linux than on cygwin. I'm afraid of all these dependencies grass has (gdal, ...).
