PDF and U3D
Arbortext IsoDraw can import and export files in PDF (*.pdf) format. PDF 1.6 (Adobe Acrobat 7) and earlier formats can be imported.
PDF 1.6 and later files can contain interactive 3D drawings embedded using U3D, the Standard ECMA-363 Universal 3D File Format. You can export Arbortext IsoDraw CADprocess 3D IDR files to U3D (*.u3d) files. 3D-capable PDF readers can open the exported U3D file. (For more information on the U3D file format, see the Universal 3D File Format presentation on the Ecma International website.)
