How to revolve a thread on a curved surface

I am attempting to revolve a screw thread on the ext. of a curved surface. When i revolve my thread (triangle shape) off the axis, it will naturally not follow the ext. of the body’s curvature its attached to. Is there a way to do this?

You can project a line around the curved surface first.

Hey Stephen, thank you but I don’t see how that would work. Can you send a video?

Unfortunately I’m too new to the server to post a video, I’ve adjusted the original wording to try and help you understand. Hope it helps!

For anyone who is curious, I haven’t yet tried it but here is the response I received from Shapr3D

Thank you for contacting us,

Yes, sweeping a cross-section along a projected path could be a solution.

Let me add the video from that support ticket for the record, hopefully, it will help visitors in the future :slight_smile:

The following thread in the meantime may be helpful for connecting separate projections accurately:
