[GRASSLIST:51] Re: v.in.dxf

[Mauro Lacy]

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,

Mauro
