Can someone help me with this problem?

Hi everyone!!!

I have a problem with this part of the mesh.

Here is the file:
File.blend (3.17 MB)

Go and tidy that mesh up.

See all those faces with more than 4 edges, get rid of them and make them have 4
Have all the edge loops have the same number of vertices

With better control over the edge loops you can get rid of those edges you have marked as sharp

Delete the highlighted vertices and remake them by extruding the remaining edge loop

Thankyou! Richard
I thought that, but I wan it to know if there was another way to do it.
