I have a problem with sweeping tool… is not sweeping…

Hi, this is my first post and I cannot figure out what I am doing wrong. I’m trying to do a sweep between 2 objects, one is smaller and other bigger. I’m marking both faces + guide line and it is constantly showing fault “Swept body has self-intersection in at least 1 of it’s geometries…

Here is link from my screen recording from loom, if anybody could help?

You could use a loft operation then use then use the shell tool.

Your sweep is failing because the arcs your created did not make an enclosed sketch. A closed sketch can be made into a body. If it is not enclosed (enclosed if it turns a light blue) it won’t revolve, sweep or extrude.
