First off—what an amazing product. I was _this_ close to jumping out the window after struggling with Fusion and I outgrew Tinkercad

I’m stuck on something that seems simple but I just can’t figure it out. I want to extrude a circle (on one plane) along an arc that sits on another plane. The center of the circle and the start of the arc intersect, so everything lines up geometrically—but I’m not getting the option to extrude along the arc path.

I’ve been hunting for the right tutorial or example but haven’t found one that matches this situation. Any tips or guidance would be seriously appreciated!

Thanks!

Are you looking for sweep along a path?

Something like this.
