Export 3D model from Blender to .U3D for use in PDF file .pdf files supports Displaying 3D models, you can view the model from any angle by mouse movements - sort of like looking through the viewport, only the object is fully rendered, "real", etc. This requires a .ud3 file. Blender does not export a .ud3 file. Any alternatives to achieve this?
You can find the scene button in the property Area, scroll down to find the u3d export.
I managed to export to u3d, but after putting it to pdf with latex the pdf failed to open correctly in adobe reader XI. a "3D data parsing error has occurred"
