Hi i am new to the forum so the searches i did may have not been correctly phrased, but I found no answers or mention of this problem.

- If the vertices of a quad or N-Gon are not co-planar, is there some way to make them so, and even more, to dictate which three vertices determine that plane?

Snapping to the grid obviously is not an option for faces not perpendicular to an axial plane.

The workaround I am using is so embarassingly complicated that I hesitate to mention it, but I can select three vertices, duplicate them, make a face ( a sad one!) and scale it up until I can snap the noncoplanar vertices to it and then delete the āguideā face.

- Is there a script or menu item to correct all N-Gons in a mesh to have coplanar vertices with the minimum displacement of geometry?

Surely these problems are very common?
