Here may inlie the problem. The diameter or radius isnt quite the issue, this was me just making something fast. It's the .002 thing.

My bobcad interface is set to inches. Is the MM thing an internal file format or are you under the impression that my interface is set to mm?

If it is an internal export function, this could be my cause to take to Bobcad. What told you it was in mm?


[EDIT] Could there be a version issue with open nurbs. MoI is on version 3 and bobcad using 4? (Am I mistaken? I am getting this from the toolkit)[EDIT]
