What version of Autodesk Inventor do I need to save a file in a catpart, and then open it in catia? I have Autodesk Inventor 2015 but when I save it as .catpart I can not open it in Catia. Catia says: Wrong application level. Do you know which version of Inventor I need? Please help me.

You can save files in format of .igs or .stp from inventor and then open in catia o even in any software

Try to do the model in catia if you want full editing feature, or even you can edit igs files from catia

a mistake it's " catia or even" from above phrase
