Conversion of sldprt files to catpart file format

You can certainly convert SolidWorks parts (.sldprt) to CATIA format (.catpart). Such sldprt to catpart conversion can be done either with some conversion utility or 3rd party app (like CrossManager)  with some kind of CATIA/SolidWorks plugin. Sometimes middle step conversion through some common exchange format is needed, due to the lack of format support.
