I have always been puzzled that the CNC machine shops can do nothing with STL files while many slicing programs can assess the shapes and actually print them without any problems at all.  I'm sure it is easier for the CAM to use other file formats, but I know that I can use STL files to do CNC on my Shapeoko.

Unfortunately, CAD software importing STLs is an operation fraught w/ problems and incompatibilities. Best thing to do is to create DXFs which mimic the sorts of drawings/prints which these folks work with and expect (annotate them well, and try to design them for ease of machining/manufacture) --- then they can recreate the file in Solidworks which they can then use their CAM software to create G-code.
