Are the data really like that (could you extract just a single building to check?) or is it NVIZ which behaves like that (which I also see in my 3D data)? > I have tried v.clean in the vector layer but this makes no > difference.

To be sure where the problem is, please export them to VTK and then visualize in Paraview (there is a Wiki page explaining that). If Paraview shows the same, then v.extrude may have a problem while otherwise it may be NVIZ. Best Markus > Thanks, > > Paul J.
