[OSGeo-Discuss] Using v.overlay to crop 3D vector contour map - I can only get 2D output

[Mark]

I've tried using this feature but the only way I can make it work is to use the vector as ainput , type line and the region mask as binput type area. The resulting vector is only 2D. Is there a way of keeping 3D vectors over a specified 2D area?

Thanks Mark
