Hi Michael,

I just looked at the solids++ library you are using and one of its features is a precise hidden line removal:

Quote from http://www.integrityware.com/solids_features.html
"The SOLIDS++ hidden curve removal tool can determine the visibility of the edges of a Brep object from a given view point. It works directly on the precise 3-D geometry not a display approximation. The results are therefore suitable for drawing productions applications."

I have not much clue but is this something you can/will use in MoI to improve the export to illustrator?
