You can use the following procedure to output 3D-PDF from virtually any 3D software - and get this generator for free. The resulting PDFs may not be fully optimized as for their performance and the style control is rather limited but ... it is a free toolset.You will need these two free software packages:Meshlab (a 3D mesh processor)MikTEX (a TeX/LaTeX implementation), will automatically download "movie15" and a couple of other plugins on its first runHow to get a 3D .PDF file from your CAD model? Step by step instructions:Use your usual favorite CAD/CAE tool to export your original 3D model to any of the following 3D mesh formats: OBJ, STL, VRML(WRL), PLY, X3D (you can get e.g. STL from the "3D Print" function in your CAD)Start Meshlab and import the mesh file using the File > Import Mesh (Ctrl+I) function. Confirm "Unify duplicated" if prompted.
