What troubles do these warnings cause? I see no problems with the renderings, no
matter what renderer I use.
How do I correct them? By splitting all the quads into two triangles each I
guess? If so, why not make a tool that splits them up?

| (...) If I remember my 3D theory correctly, these quads can mess up the normals associated with them. Also, noncoplaner quads cause small gaps in the part since they are, in essence, bent rectangles. Usually these gaps are too small to see, even (...) (21 years ago, 17-Jul-03, to lugnet.cad.dev)

| (...) When a renderer goes to render a quad in 3D, it will almost always (perhaps always) first split the quad into two triangles. As long as the quad forms a planar surface, this will result in fairly equivalent results no matter which of the two (...) (21 years ago, 18-Jul-03, to lugnet.cad.dev)

| (...) What Orion said. (...) Sometimes, it just means the vertices are incorrect. If the vertices are correct, then you should break the quads into two triangles, and put a soft edge (linetype 5) along the common edge. But often, it's worth looking (...)
