Hi, I've committed v.in.dxf in CVS and it now supports z coordinate import, which means v.in.dxf3d is not required to build a 3d vector file. The label import feature in the previous version is not yet supported. Don't forget to run v.build after v.in.dxf. In addition, v.surf.idw can read in z values from a 3d vector. Huidae Cho
