[GRASS-user] create 3d plane from vector lines

[Carlos "Guâno" Grohmann]

Hello José.

v.surf.rst is not exactly what I want here, although I could duplicate
my vector lines with different elevations and then interpolate the
values to get _raster_ surfaces. I was thinking more in a v.extrude
way, just that it currently extrude areas to form facets or shifts
lines, but it doesn't create planes from line (AFAICT).

cheers

Carlos
