Revolving spline/polyline around ellipse

[cr08]

Hi there. Found this forum and hoped to get some more experienced help with Autocad usage. Used it a while back but unfortunately all my knowledge has went out the window so I am starting back over from square one.

 

Anyways, I have AutoCAD Mechanical 2006 here and am getting stuck on trying to do a simple revolve command on a polyline. Problem is I do not want it revolved in a perfect circle but more in an ellipse shape of my choosing. I attempted to tell the revolve command to do so around an ellipse I drew with the centerline being aligned on the axis for the polyline to be revolved but it would not take.

 

Any ideas what I could do here?

I took a slightly different approach by using the EXTRUDE command. I did it for one-half of an ellipse then mirrored it. This is the result. Would this approach be acceptable to you?

Revolve works on a fixed point and will take your linework and spin it around that central point, much like a pottery wheel. You cannot create irregular shaped objects with Revolve.

 

Using 2006, you will need to Extrude along a path as in ReMark's example.
