I have this shape I’ve made from lofting three triangles then capping it. I am also converting it to a mesh shape.3dm (97.2 KB)
I am having trouble finding a command to triangulate it into planar surfaces; I seem to be getting some triangular surfaces, but others remain nonplanar.
For something this simple, instead of lofting it I would just build it directly out of 3 sided surfaces with the Surface from corner points tool. Or, as you want a mesh, do the same thing with the 3DFace tool and then just join the faces.
Or, just make your entire wireframe out of individual line segments like in the file below, then use MeshFromLines.
Yes, to apply your process to all or selected individual faces of a polysurface, instead of having to do each one individually. You can also introduce some more logic here, for instance only triangulate faces that have curvature and/or don’t subdivided faces that already are triangles, and so on.
Generally,Grasshopper is geared more towards parametrization, but it also works great for automating design processes like this.
