#91 it errored out and said to send this

[Daryl Spitfire]

Hello,

I just downloaded PyCAM to try it. I made a simple (3 solids) Autocad 3d model (see attached). My 1st attempts all failed with 'failed to import STL'. So I searched your forum and found possible issue with Autocad binary stl. So, instead of "export to stl" I used stlout command to an ascii file. That imported into PyCAM ok. I took all the default settings except I changed all the tools to 0.5 diameter, ball with 0.25radius and toroid to 0.1radius. The I clicked for "Generate All". After about 15 or 20 minutes it bombed out with the following error.
