Smoothing mesh problem

[jasper_bravo]

Anybody know how to make this look cleaner? Can't seem to find a way myself.

Hi!

You have quite a few N-Gons (Faces with more than 4 vertices), also it seems like you have some overlapping Edges that aren't merged on the left side of the arch.

Try running the "Mesh -> Cleanup..." command and the "Mesh -> Retopologize" command before smoothing your mesh.

I hope it helps!
