Threaded hole drill size

[Lonnie.Cady]

Are there any plans to allow us to override the tap drill size on threaded holes?

I can't speak for AutoDesk so I don't know whether this has been discussed or is on any roadmap. It might not be convenient but you could create new thread files with the modified tapping drill sizes you require.

Hope this helps.

Thank you for the response.  I have seen the suggestions about modifying the files.  It's not a huge deal just would prefer to have something built in.

No problem, you're welcome. To be honest I've not managed to find anywhere in Fusion where the tapping drill value from the thread file is used. For example, if you take M6x1, the tapping drill specified in the thread file is 5mm. However, a value of 5mm doesn't appear anywhere in the hole dialogue or in the drop-down list of available parameters in the drawing environment's hole callout dialogue.

I'm pretty sure that the Tap drill size is used by Hole recognition in the manufacture workspace

[MRWakefield]

Thanks. Yes, I thought that too but when I asked the forum the question (admittedly that was probably a couple of years ago) no one came back to say that it is used anywhere in the mfg workspace. In fact, I seem to recollect that someone from AD replied to say that they weren't aware of anywhere that the tapping drill value was used. There will have been many updates to Fusion since then so it's quite possible that this has changed.

You are correct, I did some testing by changing the values in the .xml and Hole Recognition only uses the Minor Diameter

[MRWakefield]

Thanks, I don't have any cause to use the manufacturing environment so it's good to have it confirmed.
