I created an arch mesh, but the mesh is not an arch. How to mesh only the arch.

Your loft was wrong.

Why are you trying to do a mesh here?

you can loft the horizontals or the verticals, but not both at the same time.

This model does analysis and requires 4 supports.

Is there a component that can have multiple lofts?

Perhaps you are thinking of Curve Network

Network Surface Component
