Hi Warewulf,

Your subsurface engraving software most likely orders the points in ascending/descending order relative to the focusing axis of the laser (usually Z).

Can you post, or email me a larger .CAD file to check? I sent you a message with my email address yesterday.

You can try AccuTrans 3D from www.micromouse.ca to translate polygon files to .ASC format, and many others. Its also useful for moving, rotating or scaling models when saving. Its good and cheap at $20.
