I'm looking for a converter that allows me to transform catparts to stp. The main problem is that the solution must be a freeware or a cheap software due to the compay does not allow any kind of craked sofware.
Creating problem from not problematic condition. Where do you get the .catpart file. Find the source and want them directly .stp.
its free to convert the any CAD software file
I can say that it is not easy to find an appropriate free sources.
But I know some of them. And with great pleasure share with you:
