Hi,
I see that similar sub-surfaces of a polysurface produce different results when meshed.
Some are squares, others get triangulated. I changed settings without any luck.
QuadrangulateMesh doesn’t do anything either.
So, for this simple case, what is the solution to get only quads of 200mm max lenght?
Thank you!
polysrf to mesh.3dm (2.7 MB)
Keeping the simple planes box ticked will get you there for the sides, but top and bottom need triangles.
Or you can MergeAllCoplanarFaces on the Nurbs object before meshing to get this:
Or mesh the Nurbs object then MergeAllCoplanarFaces on the mesh object to get this:
which is maybe what you want? Note though that top and bottom are n-gons, not rectangles, so depending on your purpose, this could be a step too far.

Hi @jeremy5 , thanks for your reply!
What I actually need is Quads with around 200mm in length, as I specify under mesh settings at Maximum edge length.
I managed to build this:
I extracted the top and bottom of the nurbs object and meshed the sides as before, then scaled them vertically by 0.1, before arraying them vertically x 10 to get back to the original height. I then meshed top and bottom, reducing the number of polygons so that I got the central rectangles and outer triangles. I joined all the meshes and then welded them.
I should have scaled down by 1/13 and arrayed by 13 rather than 1/10 & 10, but otherwise this seems to have worked. Not an instant fix but it gets there unless the remaining triangles on top and bottom are problematic.
Regards
Jeremy
hmm… i understand. So there is no automatic solution, specific settings?
@leopoldomonzani ! looking good!
Could you be more specific with the settings you used? Thanks.
Grazie mille !
Trimesh vs Quadmesh:
Triangular meshes (tri-mesh) are preferred for GPU rendering and raw geometry, while quadrilateral meshes (quads) are preferred for subdivision, animation warping, and modeling.
Dunno if you’re into python, but this is the module you want : https://trimesh.org/
For specific quad-meshing (automatic conversion) tasks, tools like QuadriFlow can be used in conjunction with initial triangular meshes.
