Hi, I am trying to extrude a profile of a ring. As you can hopefully see in the attached image, I have the spline for the ring and two profiles Top & Bottom. The top profile is larger than the bottom profile since I want the ring to taper in @ the bottom. How exactly can I do this.

Many Thanks

One profile and two or more splines that taper.

Cheers,

Well I did a plane with the basic profile you want. I extruded it, then taper the center of this kind of cylinder and then bend it 360š. I get something similar. My result itīs not important and surely not exactly what you want but the way I use may be useful, I think.

Image:

1-result
2-plane
3-extrude and get a cylinder(with bandsaw )
3- taper cylinder
4-bend 360š

EDIT: Just a couple of minutes. Another way to get it

I have managed to do it like this, with both splines rotated to the desired angle.

Many thanks for both speedy replies.

Here I created a quick video showing how you could do this in LWCAD.

LWCAD really does rule.
