Revolve a 3D Sketch?

Does anyone know of a workaround for not being able to revolve a 3D sketch? Projecting that 3D sketch onto a plane is not a valid solution because it won't re-create the same surface.

Thanks

Correct Answer

I've done it this way before:

Sweep a circle with a straight line as the main guide curve.
Use the 3D sketch as a guide curve.
Constrain the circle section center to the straight line guide curve, and constrain the perimeter of the circle to the guide curve using a point.
Constrain the point coincident with the perimeter and also to the guide curve using pierce constraint.

p.s. Sorry that I can not look at your example due to being a version behind.

Actually, I'm more interested in revolving a 2D sketch around an axis that is not in the same plane. I'd like to revolve Sketch 1 around Axis 1 in the attached file....

I'm not so interested in the revolved surface, but in the intersection of the revolved surface and Plane 1.

Thoughts?

Thanks!

Nevermind. I solved it using a 3D sketch and a Surface-Sweep. I've attached the soln in case anyone else needs it.

Thanks

This is the solution to your question, using the Revolve feature.

Hey Alin,

That doesn't work. Sketch 1 does not completely intersect Surface Revolve 2. I used the Sweep command from my earlier post, and they produce different surfaces. The sweep one is the one I was looking for. Thanks for your help though!

My bad, you are right.
