Conversion of catpart files to stp file format

CATIA software is certainly the best option for any catpart to stp conversion. If you do not have access to CATIA, you have to look for some 3rd party software which offers CATIA format support. You can even find dedicated 3D modeling converters and exporters that can help you open or convert catpart to stp.
