[GRASS-user] import dxf 3d polylines

[Vincent Bain]

Hi list,

I need to import a dxf file containing 3d contourlines. I was convinced
v.in.dxf was able to do that, unfortunately, it seems it does not. My
contour lines are imported flat, ie with elevation set to 0... and no
specific field provided with altitude.

Reading the man page I see one can import 3d faces, but nothing about 3d
polylines.

Has anybody else dealt with this situation ? would there be an
alternative such as multiple formats transformations with tools like
Meshlab, Paraview, blender...?

Thank you,

Vincent
