how i see there are a Projekt tu create/ export 3D PDFs.
so what i need is an importer for 3D-PDFs
How I do it reight now?
I open the 3D PDF with the Acrobat 3D 1.0
it is Acrobat 7 or so
i use the function edit in 3DTool
safe the 3D Parts as U3D
than I open the U3D File with TurboCAD Platinum
and than I can safe it in the file format I need.
What i figure out is that Intel has an libary for U3D support and has an parser for it.
Maybe some of ower great developers spend some time too check that out. and creat a 3D PDF or U3D importer.
