How to Model a Thread Through A Chamfer?

[Anonymous]

Hello,

I'm a student learning Fusion 360 for CAD/CAM work.

I'm modelling one of my school assignments, a manual turned spindle body.  I'm having trouble modeling a 1-14 UNC thread past a chamfer.

I sketched the entire profile, then revolved it, and modeled the thread on the diameter.  The thread does not penetrate through the chamfer, and I cannot add the chamfer faces to the thread modeling face.  I tried removing the chamfer from the sketch, modeling the thread, and then applying the chamfer, but this does not work either.

Any ideas?

Export your *.f3d file and attach it here and I will create video on solution using your model.

Hello all,

Thanks for the replies.

I tried the suggestions shown above. Creating a custom thread profile and
sweeping the helix worked ...but it lost the thread spec (1-14 UNC 2B) that
was available to me using the 'thread' command, and was therefore less
accurate. It was also more work.

The second work-around involving disabling and shuffling around the thread
and chamfer commands has ceased to work.

JDMather,

I believe I reset the file permission to allow you to access the model:

Here's one way to do this:

Whoops, I'm not sure why my last message isn't displaying.

Either way, I misunderstood the request to upload my file.  Here's the requested .f3d file.

Thanks again!

etfrench,

I finally had a chance to sit down and watch your video, and had to chuckle at how clever your solution is!  Very smart and maintains the thread spec too ....even if it's still a lot of work.  Thanks!

I hope Autodesk can debug the thread modeling command eventually.
