Here I have two surfaces, running Paneling Tools > Create paneling Grid > Surface 3D distance on both, using the same U and V distances, works for one and doesn’t work properly for the other, regardless to which reference point on the surface I use.
This is the Dir for each surface
It works though if I flip the U direction of the surface! I guess this is not how it is supposed to behave right?!
