Tony-
We here at Brown & Sharpe have a product called RefleX Scan which is typically used for reverse engineering on manual machines. It can take an ASCII file in the form of
"X 232.123 Y 324.565 Z 342.435"
"X 545.545 Y 345.345 Z 435.434"
and convert it to DXF, IGES, VDA, or GCODE. It uses tip center information and thus, no ijk. However, it may be possible for you to write a simple macro which would do the tip comp. If you are interested, let me know and I'll get you in touch with a sales person. Best Regards,
