I have written a script that runs inside of Blender (open-source 3d program) that basically takes a photo and creates a 3d mesh of it. Normally I export from Blender as stl and open that in my other cam program, Millwizard; however, Millwizard only allows me to raster cut it in x and y. The results are great, but I am looking to use BobCad so that I can run multiple toolpaths on the geometry. For instance a V-cutter around the eyes a ball nose mill for most other areas without the wrinkles or eyelashes. I tried using Rhino to convert the dxf to iges and step for Bobcad, but they don't support polygonal meshes. Either way, I would like to be able to use BobCad for more than 2d profiling and solids from Inventor. How can I either make a machinable surface for Bobcad out of the many different files I can export to for Bobcad?

Here's a linke to my work so far (page 2 has the images and examples of bas relief wood cuts I have done): From Photo to Woodcut!
