Can anyone clarify just what the surface is ignoring part of the border, and skipping portions of the feature lines?
The bulge is easy enough to fix, just by deleting the lines the extend beyond the border - but should not having an outer border prevent the tin lines from crossing?
The concave dent in the surface on the other hand, makes zero sense. The cyan and reddish feature lines are inside the outer border, and have all been added to the surface (actually the feature lines are continuous and ports of them are included in the surface, but there's a neat arc carved out)
