Conversion of step files to fcstd file format

FreeCAD supports both import and export of ISO-10303 STEP product data files (.stp, .step) and therefor is pretty much the get go option how to achieve step to fcstd conversion in order to transfer 3D model / CAD data. You can download FreeCAD from SourceForge, so should be easy enough to achieve this type of conversion.
