Hi Pilou, I have not really looked that deeply into 3D PDF, it's pretty much a completely separate thing from the regular 2D page-oriented PDF stuff.

It would need completely separate code for trying to read in the 3D PDF stuff, I don't really expect to be able to do that.

Also 3D PDF files are not generally used as a method to transfer 3D data between applications, they are more used for output only to make a file to be displayed in the PDF viewer.
