Hi, im looking for a method, how I can simplify a complex 3D mesh into quads, where all 4 vertices of a quad are on a plane. I think normal quads in blender still mostly have an invisible edge and therefore consisting of 2 triangles. In the further process, I’d like to manufacture that low poly qu…

It’s an addon, you have to enable Planarize in Preferences. Then just switch a mesh to Edit Mode and use Faces -> Planarize (bottom of the menu). All faces with more than three sides will be made perfectly flat. It does quite the same as the Make Planar Faces operator – just better.

Thank you very much! I just tried out the “export to paper model”, and it works like a charm. I’m not relly sure now, if I even should go for coplanar quads, since, it doesn’t really matter. Tris could be even a bit better, since I think they don’t buckle that much. Anyhow: can I scale the quad’s …

[image] Alan_Talbor: Convert tris to quads sure, but the generated quads are not coplanar (one of the 4 vertices is out of plane). How could I solve this?

There is a built-in Make Planar Faces operator. If you crank up the iterations parameter, it will produce quite nicely flat quads. I spent some time working on actual computation that would do this. It’s contained in my Add Dual Polyhedron script but that script is not available in blender 2.80. Yo…

[image] emu: You can try it – if you think it could help you, I’ll update it. Wow, great, that’s what I was looking for. Unfortunately I have installed Blender 2.80, so how could I try it out, if it is not available in Blender 2.80? Greets, Karl

Here is a version for 2.80: planarize.py (Save as… -> import in Blender). It was quite easy to fix.

can you make short video to show how it work and use it I tried to run it in text editor but does not work ! and what is it suppose to do ? thanks happy bl

I check the operator and not really that good and it work on only one face at a time! I would prefer to have it as a simple script in text editor and not have to modify list of scripts every time blender changes also not needed a lot of time only on rare occasions will see if I can modify it t…

Thanks EMU, your tool works perfectly!

a quad is 4 verts
if on same plane then it is a coplanar quad
if not then it will render like 2 tris

you should start with a mesh with quads in first place
then you can unfold it to get all the faces

hope it helps
