eAxle STEP Rebuild in SolidWorks

I have a complete eAxle assembly saved as a single *.stp file and a set of dimension-driven requirements that must be preserved. I now need the entire model recreated natively in SolidWorks so every part shows a clean, editable feature tree rather than imported surfaces...
