Respected Sir,
Can we create a part which have a different drw. e.g. (Casting & Machining)?
You can do this several ways. The idea is that you have 2 parts regardless of what you are doing.
You can use family tables to suppress features for the cast part and activate the machining features in a separate or master model.
You pick which instance goes into the drawings.
Creo also allows you to make a casting part which is assembled into the next-level machining. Creo lets you make assembly cuts for just such an occasion.
And in case it is useful, you can also add as many models or family table instances as you like to a drawing.
