Re: digitizer probe and software

Hi Matt,

Look at:

http://www.sdsc.edu/tmf/Stl-specs/stl.html

For some stl info (not much).

PLC's (Point Line Circle) are in Vector's manual.

This is a DXF info site, but may not be up.
http://131.175.64.54/tools/dxf/intro.htm

Various companies tend to handle DXF's differently. I initially saw a
BASIC program example for DXF's (lines), and wrote code using that
info.

Hay, *I* could use more DXF info! I think AutoCad had some doc's. Just
starting to "research" the STL's.
