Markus,

   I just tried a different approach and this failed, too. But, the command
output follows my description.

   Using the wxPython GUI I selected '3D' mode first. Then I added the DEM
raster map followed by the vector maps of streams, lakes, and proj_pts.
Lakes does not display (see attached screenshot), but it appears that the
centroids in that map are displayed.

Commands:

Starting 3D view mode... 
Loading raster map <aber5m at beaver_lake>...
Loading raster map <aber5m at beaver_lake>...
Translating colors from raster map <aber5m at beaver_lake>...
Loading vector map <streams at beaver_lake> (points) failed 
No points from vector map <streams at beaver_lake> fall within
current region
Error loading vector map <streams at beaver_lake>
Vector map <streams at beaver_lake> loaded (905 features)
Vector map <lakes at beaver_lake> loaded (44 points)
Vector map <lakes at beaver_lake> loaded (338 features)
Loading vector map <proj_pts at beaver_lake> (lines) failed 
Vector map <proj_pts at beaver_lake> loaded (5 points)
No features from vector map <proj_pts at beaver_lake> fall
within current region
Error loading vector map <proj_pts at beaver_lake>

   The streams map is of type lines, not points.

   The lakes map is of type polygons and is just below the center red point
symbol in the attached screenshot.

   The proj_pts map is shown, but the lakes map is not.

   What might be going on here? And, how do I create this 3D display so I can
add notations (in the GIMP) and make a nice presentation?
