We use Adobe 3D as our translator to produce a 3D PDF file. Vitually ALL CAD Prog Data can be converted without having the respective license. All 3D-PMI(Text,Notes & GDT's) are automatically converted + all properties. With the specific Import configuration the 3D PDF can be converted to Step, IGES, Parasolid or VRML. So long as you have the Adobe Reader 8.1 the PDF's can be opened and read.
You can cut sections, add your own notes etc., measure, and, and, and.
