In order to make your customized products available in the 3d environment, we need models.
Models are 3d files of your products. We have the capability on our end to clean up models and work from a number of different formats. Basically, we just need a 3D file in any of the major/recent formats. These include, but are not limited to:
SketchUp .skp
AutoCAD .dwg and .dxf
Collada .dae
