Quote - Maybe snap to, but Autogrid sucks. It creates geometry at all kinds of weird angles. the only time it works if if the surface is on one of the axis and is not rotated in any way.

Autogrid has caused more problems for me than it solved. I refuse to use any longer. Its a great idea, but does not implement well.

Autogrid uses the face normals.  I don't know how you were trying to use it, but it does what it says, and never any probs with that.

Edit: if your triangulation on a quad is screwed up, then that might cause unpredictable placement, but otherwise, can you show an example of how it isn't working right?
