Doug – Kathy's at Comdex this week, so I'll answer your question.
AutoSketch will write a DXF file, an ASCII description of the drawing file.
Given your knowledge of "C", were you reasonably well versed in the
structure of DXF files, I don't think it would be too hard to write a
program that could parse an AutoSketch DXF, find the needed information,
and write it to a file that could be used as is or imported to a
spreadsheet or database package. I believe this is the route that would
yield the richest results. If we can help you with specifics about DXF
files, please ask. Do you need a copy of our DXF specs ? If you do, leave
me an address, and I will send them to you. – Jeffrey Pike.
