v.in.dxf

[David Viebrock]

The problem may be in the GRASS vector map.  You may have overlapping 
line segments which result in two lines intersecting but with no 
connecting nodes.  This results in a "dangling" segment.  If there are no 
obvious dangling lines then run v.digit and make sure all nodes are 
snapped.  You might also try running v.support before v.out.dxf and 
increasing the snapping threshold somewhat.  Careful with this one as it 
may have unpredictable results (in my experience anyway).

Also, you might want to check out the v.proj command if you're trying to 
import it to another LOCATION.
