The chord height options sounds very interesting. I'm curious for it.

Straight upward means something like this ...


... 100 degree - I set this high angle because I tried to get control only by the devide option. I'm quite happy with the result, only the missing quads. The initial uv layouts could be alligned, if fillet and top surface would be created per sweep allong a side curve. I understand.

I tested how good could be a mesh (#9) created only by "devided ..". I wonder me, that the right surface show some triangles. The initial uv layout should be quite good to create a mesh of quads only or?



Or here - additional polygons at the lower edge ...

... and from down view

... also "avoid smaller than" 2 dosn't help.
