Problem with Evaluate Mesh

Grasshopper
1

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?

Greetings Markus

Are the points definitely not on the mesh or is it a display issue? I sometimes have points that are not displayed correctly appear to be in the wrong place.

Also, from your definition image above it looks like all your components are set to preview so maybe the points that appear not on the mesh are in fact the PopGeo points?

Use Triangulate mesh
