could someone please explain why some of these surfaces are not extruding along their normals…I have tried several combinations of vectors but some extrusions are always going along the surface rather than in a normal direction.
thanks

this is how I formed the main surface …just in case it is relevant…

Thank you Joseph…so introducing srf closest pt makes sure that the normal is on the correct plane whereas centroids may not be…?
Not quite. Area ‘C’ (Centroid) is not the same as Srf CP ‘uvP’.
