How to properly create followme/sweep

[HeadbuttJ]

I want to create a sweep as shown on the photo, but the result is not what I expected.

Do I need to remove the faces/lines one by one and create new faces to cover the holes? I am wondering if there is any easier method.

I wouldn’t make that in one “piece” with Follow Me. I would create one arch and then copy it with Move/Copy. Then use Intersect Faces at the junction and erase the waste.

But the created followme is not a solid, I cannot perform solid tools.

I didn’t say anything about using Solid Tools, did I?

You could make the extrusion solid if you want. The one I made was solid. But it’s not required for Intersect Faces.

Follow Me plus a little cleanup in the middle joint.
