Hi
I`m using grass61 on windows and would like to import dxf and dwg files,
but it is only possible with dgn files using v.in.ogr.
Is there any other possibility to do an import for AutoCad files?
thanks

Stefan, you might want to take a look at OrbisCAD (please search
Google, I don't remember the URL, but I know it is in Sourceforge).
According do the authors, it can read DXF and export shapefiles.
Hope this helps

Sorry for the cross-post, but I'm trying to do almost exactly the opposite. That is, export a (raster) DEM to dxf. I was browsing the diverse grass modules, and the problem is I couldn't find a way to convert a raster DEM to a vector "surface" or "3d" file. So I can later export it using v.out.dxf. I tried r.to.vect with horrible(and maybe simply "not applicable") results.
I found some (non- free) programs that seem to do this (r2v, from ablesoft, by example) but it intrigues me if it can actually be done with grass(or with free software).
Thanks,

So you're trying to to export a "mesh", like a 3D vector grid of your surface?

Exactly. I can see that nviz generates this "mesh"(let's call it the "Wire" nviz Surface/Grid Surface Panel mode). But I don't know how to generate an equivalent vector map with this, from inside grass.

Hi,
Maybe you could try r.to.vect in point mode, v.delaunay then v.out.dxf.

Sounds like you want a TIN. see:

We need someone willing to write a dxf in/out module for GRASS. Using OpenDWG libraries is only a partial solution.

This looks promising. But seems to be work in progress:
http://www.bowdoin.edu/~ltoma/research.html
(see r.refine)
And as far as I can tell, no source code is available.
or v.3Dtin
http://www.fle.czu.cz/~jachym/programs/grass.html
http://grass.gdf-hannover.de/twiki/bin/view/GRASS/GrassAddOns
This works! (altough v.delaunay is _extremely_ memory consuming)
After some minor corrections to v.3Dtin perl code, I was able to generate a 3D-vector TIN (altough maybe it should be more appropiately called a TRN).
I'm now stuck with the DXF file. v.out.dxf generates a valid DXF file, but it looks like 2d, not 3d.
Probably is just me 
I'm displaying it in qcad (I don't have Autocad at hand now). And maybe I just don't know how to display it in 3D.
Regards,
Mauro
