PDF vector PS Illustrator

I always though the Kineme PDF Renderer patch was for exporting not importing until I just tried to use it the other week.

Now I keep finding reasons to desire a plug in that can translated point and line structures into a PDF based on the Viewer Window Perspective. (Other 3D objects like cubes, quads & spheres would be great too ;) ) Obviously one can snapshot or render in Quartz Crystal to a TIFF but I'd like to be able to grab art-work of points and lines and use them in Illustrator as vector artwork ie. lines (line structure)and circles (point structure). This would allow some 3D QC magic inside (pretty much) 2D Illustrator.

I can't think of another way to do this unless one can export to a 3D file then import in a 3D app then print to PDF to get the paths in 2D.

I just made a double helix quickly in QC but tracing it off in Adobe Illustrator is boring, especially if I want to change the perspective.
