Bug in Mesh evaluation or Mesh closest point parameter output

[HS_Kim]

I usually use triangulated mesh in this kind of situation and check the link below to get an insight into whether it’s a bug or not…

Does Mesh Eval fail to preview points?

Hi, Points of Mesh Closest Point seem to be different from ones of Mesh Eval on this canvas, but their coordinates are the same(Mesh Closest Point works precisely). Is this a problem of the rhino viewer? In this case, are normal vectors of Mesh Eval precise outputs? [image] unnamed.gh (59.7 KB)

Problem with Evaluate Mesh

Hi everyone, I’d like to get the normals of a mesh at certain points. Therefor I use “Mesh Closest Point” and “Evaluate Mesh”. Unfortunatelly some points from “Evaluate Mesh” are not on the mesh (green points). Does anybody know, why this happens?
