Formats recognized by Rhino

I sometimes import models drawn in Solidworks into Rhino 5 for a quick metal render using anylyze/surface/environment map. I import as a iges file. Are there any other formats that
can be used that will be recognized by Rhino5?
Thank you,

STEP is another good option.

If the SolidWorks is an older version, then Rhino can open SW part files directly too.

Thank you John!
