Hi Martin,

Yeah that looks a lot better! So yeah your original problem was because of that "objects sticking through each other" type thing.

If you're using OBJ format for getting stuff over into Cinema4D (which would be the most regular way to do it), any curves are just ignored, only surfaces and solids get meshed and exported out to OBJ format. So generating intersection curves shouldn't make for any change in your OBJ exports.

If you're doing something like exporting using IGES format and using some IGES import plug-in for Cinema4D to import, then that could be different.

If you don't want those intersection curves around you can use Undo to go back and erase them after you've done your PDF export, or assign them all a particular name after creating them so you can use the scene browser to hide them or select them all later on for deletion.
