Controlling threaded holes by expressions... NX9

Controlling threaded holes by expressions... NX9

(OP)
Is this possible?

I've built a number of library parts and some of them have tapped holes that change sizes based on other inputs.

Ex: 3/8-16 becomes a 1/4-20 at the same location.

I've never seen a way to switch these up other than the dialogue. So, up until now I've just shown the tap drill using the basic hole feature which is controllable by an expression.

TIA for any help

RE: Controlling threaded holes by expressions... NX9

Attached is a sample part. Open it and go to the expressions dialog and simply edit the expression named 'Thread_Size' from "3/8-16" to "1/4-20" and hit OK and the threaded-hole will update. As long as you enter a valid thread size this is how it's done.
