Face has double sided normals, can't conform them

Chris Bruin

I'm having a problem with my normals in Maya. I had created a CV curve and rebuilt it, then lofted it to make the above shape. I was planning on deleting the edges I don't need for a smooth face, but I can't because they are border edges, which I think is because of this double normal problem.

Does anyone know a solution to make only one side have normals, and why it happens?

Isn't the issue that you have faces on both sides of a planar surface? Wouldn't the solution be to delete the faces on one of the sides?

I tried that, and there are two faces. However, it deletes one side or the other, not only one side (Camera based). There are only 2 verticies per edge, not 4 as there should be with 2 faces on each side. I will try to manually delete them, but I am still confused as to why this happens.

You have what is called lamina faces (two faces sharing the same vertecies) Use mesh > cleanup to get rid of it.

or you can select the object and do merge vertices's, it usually works if not use the cleanup and it should do it.

you can try on normals click on set to face.

serialkiler: by the sound of it, that's exactly what caused him the problem in the first place. A lamina face is two faces on top of each other with merged vertices.
