Hello Hik,
We must have missed this thread because it wasn't located in the SolidWorks forum. However, what you need is a "Direct Translator" between SolidWorks and Catia. You can find them as an online ASP service or as stand-a-lone applications. Try looking here to start with:
Translation Technologies
http://www.translationtech.com/
AutoWEB

CADCAM-E.COM, Inc.

Good Luck!
