I have made a circle on a flat area then inset it. And then to imitate a speedometre I have extruded the mesh selection. As seen on the left bottom edge of the topology the ends are a bit sharp, and on the right more circular. I used the knife tool, rather than adding another loop, but made Ngons and some triangles, I'm trying to clean the topology up, can anyone post how the topology could be better?
PS: adding a loop towards the down topology can fix this issue, but Ill be adding lots of the semicircle extruded groves on a larger surface, and could possible ruin other parts of the mesh, so this is why I'd like to know how to get a better topology just in that section.
