Hi Dave, yup I definitely want to significantly enhance the illustrator output in the future. I'm hoping to make progress in this area in version 3.

Ideally it would fit in as part of an overall 2D annotation and detailing type mechanism. That would be the kind of thing where you would be able to switch to a kind of paper-oriented 2D view which could be populated by a hidden line generated view from the 3D objects, with silhouettes also being calculated during that process.
