Thread Chamfer

[HughesTooling]

I'd like a way to chamfer the end of threads. If you chamfer a cylinder then add a thread what you get has an undercut, if you have this 3d printed in will not work. To get the correct chamfer you have to thread the cylinder the use a revolve cut. One way to get what I'm after might be to allow the offset and length to extend past the length of the cylinder.

Here's an example of what you get threading a chamfered cylinder and using revolve cut.

@brianrepp Any news on this? There was no solution, only workarounds.

I think the reason that it works is because of the possibility of toggle between Cosmetic and Modeled threads.

First time I did this I expected the toggle from cosmetic to modeled thread to break the chamfer and was pleasantly surprised when it didn't.

Looks to me like it was done right (at least for the threads that I use).

As this thread just got bumped I thought I'd point out:

Actually it works because the cylinder that creates the OD of the thread still exists after adding the thread. If you're careful you can add a chamfer after a modeled thread if you pick the point the outer cylinder intersects the end face so any work to fix chamfering thread should not break old designs. But as I've pointed out it doesn't work for threads with a filleted crest.

I have resubmitted the idea here partly because the new hole tool adds the hole and thread in one go.

Thanks Mark

The workaround does not work on my internal threads inside a hole.

The solution is easy.

Is there any plans to make this more easy/intuitive? Why cant the chamfering tool just work over an existing thread, or the thread tool have a selection to also add a chamfer the same size as pitch.

1. create thread unmodeled

2. add chamfer

3. edit thread > modeled

Thanks, but I am aware of the workarounds since I have had to google how to solve this. My question was that are the developers aware of this issue that has been known atleast for 9 years, and are there any plans to make it better. If you have to google or fiddle around with features to make a simple chamfer, then I think there is room for improvement, as I did suggest.
