Hole Callout for a hole that is both countersunk and counterbored.

[BOPdesigner]

Hi NX Users, I have a case of a hole that is both countersunk and counterbored. In NX 12, since you can't create it in one hole feature, I am wondering what the proper way to dimension such a hole is. In the example, I have added the chamfer to the counterbored hole to represent the countersink. Now I could code in the countersink dimensions to the right of or under the hole callout as appended text, but I am not sure that follows any standard or is proper. Any thoughts?

as you have a symbol for counterbored
you also have a symbol for countersink.

so just choose it.

Right after (and on the same live of) the DIA .25 THRU add the C'Sink symbol and its size.
I realize the C'sink will be the very last thing machined so the order isn't quite right, but it is clear the C'sink is on the hole, not the C'Bore.
It may be a good idea to show a cross section of the hole to be clear.

Thanks for your input. I actually added a 2nd hole (countersinked) to the counterbored hole. Then on my hole callout for the counter bored hole (PMI Hole Callout - no choosing drafting symbols manually), I added appended text which is linked to the parameters of the countersunk hole.
