First of all.  Thanks to all of you who answered my plea for
3D clipping algorithms.  We will be attempting 3D clipping in
our GIS systems next year.

Now for my next question.  We have been instructed to work on
a DXF viewer for our engineering systems.  We will be building
the viewer with GKS.  Now:  Is there anyone who has already
done a DXF to world coordinate program?  Is there a good reference
for DXF?  Any help will be appreciated.  Presently, we are
using very crude graphics primitives to build less than
adequate graphics.

Thanks in advance.
