par to obj conversion is most likely related to searches about exporting of Solid Edge 3D part files (.par) to OBJ format, typically for the reason that Solid Edge itself does not support export to OBJ.
There are several (commercial) plugins available for Solid Edge that add this functionality, but except for that you have to rely on 3rd party solutions for such export, most notably various 3D model converters.
