generative modeling for Rhino

Hi Guys,
Would anyone know why the green lines on the image below are not normal to each surfaces at their centre point ?
Many thanks,
Arthur

Arthur,

The centroid is in global coordinates and the Eval component is looking for surface uv coordinates.

Use SurfaceCP to determine the uv coordinates at your point of interest (the centroid) and then plug that into Eval.
