I'm trying to get this extruded threading around this cut hole.
I tried cutting away the excess material, but this didn't seem to work.
You've hardly given enough information. This model creates <360 degs. of thread contact on one flank surface in one axial direction.
Another way to do it would be to have the mating part cross threaded which would result in <180 degree of thread contact on both thread flanks in two axial directions. To do this you would need to get creative and connect Sweep 2 & Sweep 3 with a cross threaded blend between them.
Have you tried using the Thread command?
Yeah I tried it, but do you know how to invert the threading here?
Is there an option to do that? Or did I pick the incorrect edge?
Being stamped sheet, it appears the thread profile is material thickness.
In addition to the helix, the material appears flared down on the inside and flared up on the top side to take up the gap from the material thickness for the female thread.
In other words, it appears to be compound.
If true, then perhaps a loft with a downward start profile and an end upward profile with a helical guide.
No time at the moment to model up, but perhaps this will help (or not).
Hmmm... I don't quite understand how I would do the loft. I was thinking maybe trying some sort of boundary cut of the excess material.
But then I get the "self-intersecting geometry" error.
As Anna Wood mentioned below, I mean this isn't a "thread" as its profile is the material thickness bent down and then transitions to bent up on the exterior:
It's a partial ring of material stamped into a helical form.
Ok makes sense, you are right. Is there a way to do this with sheet metal tools then (in Solidworks)?
That does not look like a true cut thread. It is a material thickness helical ramped shelf.
Work is backwards.... Model a ramped helix material ledge and that merge it back into the main body.
Is there a tutorial on how to do this 'ramped helix material ledge?' I'm not sure how to do this.
Google SolidWorks Create Helix
Anna, ok I understand what you are saying now. Thanks.
M.B. thanks! I think I can make do with this as I'm not exactly sure how you'd do that cross threaded blend.
