R30 CATPart Downgrade

Hi, the R30 format isn't compatible with other softwares that I'm using, so I am looking for a way to downgrade CATParts while keeping the geometries and their names when imported to other softwares. I tried the 'downward compatibility' tool as well as saving as a step file, but none of them retained the data I need. Is there another way to do it? Thank you!
