Inventor 2026 Bug - Hole Wizard, Not Setting Nominal Countersinks for Threaded Holes

JO3ATI — Tue, 29 Apr 2025 14:42:34 GMT

I've tried this on two different machines, so I don't believe it's an issue with install. I think it's a bug within the software.

As far as I can tell, the software is no longer setting a recommended countersink. This appears to be specific to the tapped hole. Regardless of the tapped hole I choose, the countersink value remains static (whatever it was when I opened the hole wizard).

Regardless to what I change it to, the number will remain the same.
I can type a custom number, which is non-ideal, given ideally it should present me with the nominal industry standard, but then if I do change to a different thread designation (even changing type), it'll maintain that input value.

Hi! I could be wrong but I think this seems to be the behavior for a quite while. I tried it on 2020 and the same behavior exists there.

Many thanks!

I thought about this after I posted it.
I suppose there are probably almost no scenarios in which you'd need both a threaded hole and a countersink in the same part, so if this is expected behavior, then I do apologize for reporting this!

Thanks for following up 🙂

Hi! Please refrain from apologizing! You did not do anything wrong. Ideally, it should work more desirably. However, there are too many variables at play, making the automated operations within the command panel very complicated. As as a result, the Counter Sink diameter carries over the last used value. For the more common used values, you may want to save the options as a preset. Then you will not have to keep typing the values manually.

Many thanks!
