Currently Fusion 360 imports only Surfaces and Solids entity types from STEP files. Wires and Points entity types are not imported, while Inventor can do. We ask to include the ability to import at least Wires entity from STEP files in Fusion 360. That is useful for same applications, e.g. importing STEP files produced by optical design programs like ZEMAX storing light rays as wires in the STEP files. I'm sure other user can report different application cases.
