[GRASS-user] 3D TIN?

[S. Merlo]

Dear GRASS users,

I have a question about exporting TINs to dxf. I have successfully managed 
to perform the export and opened the TIN files created with v.delaunay in 
CAD. Problem is, the z value of the TIN points is 0 and my TIN is flat (not 
what I wanted to achieve). Am I doing something wrong or is this what 
should happen? Is there a command that would allow the export of 3D TINs? 
Is this an export problem only or is the command v.delaunay not producing a 
3D file?

Hope my problem is clearly stated. Any suggestions on how to create and 
export a 3D TIN for further editing in software external to GRASS is 
welcome!

Yours
