Make all control points align on a 2D axis.

I use the scale 1D and scale 2D commands allot for fast modeling projects.. but often times I scale things a little bit off, and for example, all the different planes on a wall, (ie stone vs wood), do not rest on the same plane. Is there a way to get everything to align? Is there also a way to get them to all lock together? so the model is water tight?

Set the cplane to that wall, then use ProjectToCplane.
