Why aren't the normals for the two inner rectangles located at the rectangle centroids as are the normals for the two outer rectangles? The four rectangles are supposed to be identical.

I'm running v2.80.44.



  • $\begingroup$ probably you have to flip the normals. $\endgroup$ – Michael Ben David Feb 26 at 4:24
  • $\begingroup$ Thanks for replying. When I flip the normal, it's still off center, just on the other side. $\endgroup$ – Glenn Feb 26 at 4:30
  • $\begingroup$ the faces arent cutted? can you put an image in edit mode? $\endgroup$ – Michael Ben David Feb 26 at 4:49
  • $\begingroup$ The image in my original post is in edit mode. $\endgroup$ – Glenn Feb 26 at 4:59
  • $\begingroup$ this is weird then, try to remove doubles, or better just change back to 2.79 because 2.80 its still in development and it has still bugs. $\endgroup$ – Michael Ben David Feb 26 at 5:05

Solved. Reduced problem to four rectangles and noted vertex count in status bar. The two inner rectangles each have an extra vertex.

This also shows that the location of the normal is not the centroid of the area, but the centroid of the vertices.

Shows extra vertices

  • $\begingroup$ I guess it has to work this way, to allow non-planar faces to have something you can call a 'normal'.. $\endgroup$ – Robin Betts Feb 26 at 12:20
