Convert SLDASM to FBX

SolidWorks unfortunately does not support for FBX format (Autodesk Kaydara 3D data exchange format), but you can find some plugins that will add this function to the program so users can export their parts (.sldprt) or assemblies (.sldasm) as .fbx files. Some expensive tools like 3ds Max should also be capable of this.

Blender supposedly can both import/export FBX format (with a Python script)  although the support was added without the use of the official FBX SDK and thus might not be perfect.
