Extrude between two shapes
Extrude between two shapes
(OP)
I am trying to create an elliptical rib for a part, however the rib must be tapered along the major axes but not along the minor axes. I created the ellipses for the top and bottom of the rib, they are correctly spaced. I was wondering if there was a way that i could extrude those two shapes together to make one smooth rib with a tapered major axes. Any help is appreciated.

Otherwise try the sweep tool specifying 2 sections. You can probably use your major axis as the guide.
Press F1 once you've started the sweep feature to get the help docs up.

I think you missed the point of the help docs that MSPBenson was talking about. The sweep feature his very specific how and in what order the line/curve elements are selected. Pay close attention to the cue line too, it will pretty much walk you thru it, but in a nutshell:
select swept
select the guide cure, the curve that runs between the two ends.
Then 'ok', unit the cue line asks for the first section line. Then 'ok' until the cue line asks for the second section line.
The draw back to this type of swept is the resulting solid is quite liner, in other words, the surface probably won't be tangent to the adjoining surface at either end. To accomplish this you'll probably have to add additional guide strings.
Good luck

Plenty of suggestions here, let us know how it goes.

It hadn't occurred to me to do it that way.
I suppose that if ruled surface were replaced with through curves it would be no great loss in that case. It appears that all the available alignment methods are already supported. It would simply be a matter of making sure that the legacy data was still supported.
