I'm new to Blender. I'm learning bridge edge loop.

I want to bridge two circle, because the number of verts of the circles is different, there are many triangle face that cause unevenness. I use alt+j to convert Tris to Quads but is works not so well

you can get my file from

I hope this surface doesn't have too many corners like the picture enter image description here

    in order to avoid tris you could give the same amount of vertices to both the 2 edge loops, select the bottom one and X > Limited Dissolve with an angle of 13.2 to get 49 vertices, then Ctrl E > bridge edge loops, shade smooth and maybe give it a Subdivision Surface modifier? – moonboots Feb 28 '24 at 07:29
  • @moonboots wow, thanks, it works vert well. and could you tell me how can you get the angle of 13.2? I want to try to generalize this operation – mengyuanlan Feb 28 '24 at 08:34
  • Not sure what you mean, I just tested the angle that would leave 49 vertices and it was 13.2 (in the Operator Box) – moonboots Feb 28 '24 at 08:39
  • @moonboots because this operation will appear many times and the number of vertices is not the same, so i hope the angle can be calculated so that i can code a python script to do it, Anyway, thank you for your suggestion – mengyuanlan Feb 28 '24 at 08:50

It has the expected limitations of non-adaptive resampling, but, if bridging unmatched profiles is a frequent operation, you might consider adding a simple Geometry Nodes Tool...

.. which resamples your mesh profiles to your given resolution, by converting to a curve, and back again.

In this example file, added as a local tool asset to the Header > Mesh menu:

To display the amount of vertices enable Statistics in the Viewport Overlays:
