[GRASS-user] Re: [GRASS-dev] 3D DXF output: howto?

[Benjamin Ducke]

OK, v.drape worked for me, though I find it a little annoying
that I have to first convert the elevation attribute to a
raster, than use that to grab 3D coordinates off it.

I was hoping there might be a more elegant way to just copy
the elevation attribute into the Z coordinate and create
and thus convert a 3D points map to 3D directly.

I can confirm that 3D dxf export works fine, at least for points.

Thanks a lot for the hint,

Benjamin
