Casting/Machining Model

I have a cast part with all machining features within the model, named XXXX-Cast. In the past, I have saved this type of model as XXXX-Machined and did not check save as copy. I then did something to have the machined model reference the casting model so when i made a change in the cast model it automatically updated the machined model, however when you change the machined model it doesn't change the cast model. I found this very useful. Can anyone help me remember what i did. I think it involved changing the names in Windows explorer! Or did I replace all the machining in the XXXX-Machined model.

There are several ways to do this. You can create a derived part, which is linked to the parent part. You can use the Save Bodies feature, which does essentially the same thing.

Or--and this is probably simplest--you can create configurations in which the machined features are unsuppressed, and for the cast configuration the machined features are suppressed (same part file, pick which config you want to use at a given time).

The best (imho) way to accomplish the task you are describing is to create an "as cast" model. Then create a new part in which you do an Insert>Part of the cast model. On the new part, you will do all of the machining operations.

It is my understanding that this functionality was specifically created to do the operation (and similar ones) that you require.

You will end up with two parts, one is the cast part, the other is the final machined part. If the cast part changes shape, the machined part will update accordingly.

Ah, I remember know. Thanks to all for your input. I suppose there no magical way to get the machined features in there. Well, you could but they wouldn't be editable....at least in the machined part. However, could you have a machined model based off the cast model which includes the machining(base part). Then go back and suppress the machined features in the cast model. All editing would be done in the cast model....or would it be best to then just create configurations. I apologize if this is confusing. It would be nice to be able to import the machining into the machined drawing and be editable. I like to start with the part consisting of the casting and machining as its easy to iderate and make everything work.
 
Or what would you think of a Base Part where you restructure everything so that in the tree all the casting features are first then machining features. Roll up to the last cast feature then insert new part for the Cast Part and unroll to the bottom and insert new part for Machined Part. Then every thing is controlled in the Base Part and you could have the separate files for Cast/Machined. Let me know if this would make sense.
 
Yeah, you'd probably want to have all your machined features in the tree after modeling is complete for the cast stuff--that way it's easy to make separations like you mentioned. Use configs, new/inserted parts, whatever, and it will be much simpler.

I would base the creation of the part(s) off of how they are created in real life. For instance, if you have the castings done by an outside vendor, but machine them in house, you'd have two separate parts. One being the cast part, with it's own part number and drawing and the other being the machined part. If it's all done outside, but by two different vendors, then the above would still work.
If it's all done outside by the same vendor, then you could simply create it as one part number with two configs (cast & machined).

After seeing all the links in this thread and recalling the training I had way back when, the best solution is to use the casting as the Base Part for the machining (search for base, part in SWX help). The casting is its own parametric part file. The machining has the casting as its first "feature". From there you can cut the base part just as you would machine the actual part. If the casting changes, then the base part for the machining changes. The beauty is this is all a parametric relationship. It is exactly the scenario the Base Part functionality was designed for.
