I agree with most of what the other users have said. Here is what I have found to work well.

I utilize CAD only data for parts that will be cast or molded. This is for the raw casting or basic molded part only. All the machined dimensions are put on a drawing with all required tolerances for inspection and revision control.

Since the raw cast dimensions are usually only inspected during tooling approval, we do not have a problem with not having a drawing of the cast dimensions. Also, the making of the tooling from the CAD data is so much more accurate that the casting or molding operation that the advantage of going direct to tooling from CAD data, far outweighs any benefit we may get from having a drawing of the raw casting.
