Hi MrBraun, it looks like Cinema4d lists support for 3dm files, but it looks like they skip the curves in the .3dm file and only read in mesh objects?

You might need to put in a feature request to Cinema4D that they should make it read the curves instead of skipping them.

It looks like they do support AI for bringing in curves, but AI can only contain 2D curves, not 3D ones.
