My sweep won't regenerate

I'm trying to sweep a profile along one quarter of an elliptical path. The error is that "Result of sweep intersects itself", but I'm not seeing how that's possible, and the picture Onshape shows me isn't helping. I can't help but think I'm making a beginner mistake... because that's exactly what I am. ;-)

Then you could use a surface to split and delete. I not sure that is the best way but it would work. See example.https://cad.onshape.com/documents/b0abedc6843cf229ab4f8fac/w/99c7f636901fd0928c97cbb3/e/10de34ce674fa223c1fc3ab80 -

An other thought starting with a swept surface and adding fills. The last fill closes the surface and makes a solid.

You got the idea, after looking at this a bit closer, I realize the real issue is that a sweep produces self-intersecting geometry, that is the reason it is failing not because of the collision with the existing part. Here is another way of doing what you want with fewer steps. https://cad.onshape.com/documents/b0abedc6843cf229ab4f8fac/w/99c7f636901fd0928c97cbb3/e/079e07e839ecd2d998df5827

Okay, I can do that. I'm curious as to why what I did didn't work, but I'm happy with a workaround.
Thanks!

Another robust tool for creating the solid in after you have the swept surface (or solid) is the Enclose command. It's under the Thicken command.
Enclose is handy because you can use planes as inputs...this means that you can use your cardinal (or other) planes, and avoid creating extra features or geometry.
