3D models and data saved in STEP product files (.stp, .step) are usually well-supported in modern CAD / 3D modeling tools so you should have no problem with its import. You will just need to use software that supports formats from CATIA, that is if you do not have access to CATIA itself. Some viable alternatives are listed below.

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 model. 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.
