The most easiest and convenient way to produce .catpart files is to use CATIA of course, but you may also find other CAD software with CATIA support. Models saved in ISO STEP product data files (.stp, .step) are well supported, so you should have no trouble in performing stp to catpart conversion.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned stp to catpart. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
