I'd like to export my 3D models in Blender to .U3D file format so that I can place them inside PDFs. I could use this at work when I send reports to clients, in my resume, etc. There is an old plugin that does this, but it doesn't work anymore. Has anyone out there made a plugin/fixed the old one?
I cannot see it in the the list of Import/Export. However, you can convert to another format, and use an additional tool. These formats can be read/written by Meshlab: PLY, STL, OFF, OBJ, 3DS, VRML 2.0, U3D, X3D and COLLADA. Export as one one of the highlighted formats, import it into Meshlab, and export to U3D.
