Convert SLDDRW to IPT

SolidWorks might be able to export its own drawings / parts / assembly to other formats - including the ones used by AutoDesk Inventor, which means that slddrw to ipt conversion or similar are most likely possible. Such conversion might  require a special plugin though, or some kind of add-on that adds support for other CAD formats. You can also probably find some kind of CAD conversion tool that may support this conversion.
