In CATIA, we have the option to insert a separate part body in the same model which can be used for future boolean operations. Can the same be done in Creo?
Yes it possible in “CREO ASSEMBLY”
We can insert a part body in same model
For future Boolean operations you can choose from dash board component placements
Example: you can see below attachment file (PFA)
You can do with Creo Direct Modeling app, the same way you do multibody extrudes with a single sketch in Catia .
If i am right, your question is all about creating a solid with fully constrained sketches in a plane and extruding a sketch at one and another one at a different parameters,right! PTC creo is a professional software. It is not required if you want your model to be parametric, right!. You can do it if it is a secondary operations like sweep, helical sweep,blend, or etc in PTC Creo by clicking details > rule based > partial loop...
