Sweeping between two different face shapes

[hardanger]

Hello!

I am attempting to sweep between an ellipse and a circle - the image is pretty self explanatory. Not sure how. Any help much appreciated!

The image requires a login. That's more effort than you get from me for free.

The generic solution would be to loft between the two profiles.

If you're going from an ellipse to a circle, you can sweep an ellipse with guide curves to match the path of the ellipse from start to finish.

Thanks - got it with a loft after I provided a guide line/curve

Keep in mind a circle is simply an ellipse. So you can still do this as an ellipse where the circular profile happens to have the same dimensions in X and Y axes, and the X and Y axes are controlled by one guide curve each. Similarly, you can sweep with two half-ellipses to have a final shape that differs from front to back--or in quarter-ellipses, etc.

(I used to have to do this sort of thing frequently to make good handles/hand-grips for products over ten years ago before surfacing tools became more robust.)
