I think a more effecient way is to use configurations in your part file to represent the different machining operations. For example create on configuration for turning and add a second configuration for the milling to be performed after the turning. You can then show both configurations in a drawing.
Thank you for input. I've uploaded some example files of what my current situation is.
Good afternoon Charles,
After reviewing your comments and part/assembly file this is the way I would approach your Assembly/Parts, however I don't know how many different scenarios you may encounter, which would possibly change my approach also.
1. Model the one half and then mirror the part which would take the split part out of the equation.
2. Take the 1st modeled part and the Mirrored part and insert those into the assembly
Then you could create a design table of the original half to change your assembly part requirements, or you could also try using the Drive Works Express.
The nice part about SW there are other options available and it really comes down to preference coupled with experiences, therefore the above is my two cents, there are probably a lot of other ideas out there.
