its a good thing. but my concern is hot to implement these things in pro-e. like some special ways to design it in pro-e or just regular modelling and taking care of the various parameters. hope to get a reply.
To me, it depends on the complexity of the casting. If I have to have many secondary operations (machining) I usually lean towards seperate files. A casted part and a machined part. If, on the other hand, my machining is minimal, I'll make a part family.
I prefer to merge the casting into the machined part as the first solid feature. This makes it easier to work on the machined parts without accidentally changing the casting. You can use the same casting (or forging, etc) to make many different machined parts.
