I have uploaded to WSMR-SIMTEL20.Army.Mil:

pd1:<MSDOS.SURFMODL>
XYZ21.ZIP       Free 3D CAD sys, DKBTrace/PVRay/Surfmodl comp.

Sorry for the fast turn on the version but found a bug on systems with no
mouse installed and had to fix it.  Also got the idea to take an AUTOCAD
DXF file and convert it into other usable formats.  So I took some time
to fix it up and sent it with this version.

This may be the last upload of XYZ as I will not have access to the NET
past October.  It's been fun...
