What is the methodology to transform a Physical Product and 3DShape into a 3DPart and 3DShape?

Hello,

the context is 3DEXPERIENCE on Public Cloud, so R2025x FD02 at the time of writing.

I'd like to know if there is any best practice for transforming a Physical Product with 3DShape (as seen in the screenshot below) into a 3DPart (with 3DShape, obviously).

Thanks.
