I'm on Linux, so Fusion360 seems out. (But might be doable with wine, not sure yet) However, he's on Windows, so I can tell him to try this method. Thank you! -- Sent from: http://forum.openscad.org/

@guaranteed_interwoven, if you need to have the parts converted to step format, I have windows and can pop them into Fusion 360 and send back the conversion. -- Sent from: http://forum.openscad.org/
