How come I can't open GrabCAD PDF files?

Can't open PDF files.

Can you post the file, or a link to the non-working file?
My best guess: The PDF file is a recent 3D PDF, and your viewer does not support the format. You might try updating the viewer, or using Adobe Acrobat Reader if you are using an alternate viewer.

That was the answer to my problem. I needed a 3D PDF viewer. Thx.
