Surface with specified number of points ?

Is there a way in Moi to create planar (square or rectangular) surfaces with a specified number of points.
For example a square planar surface with a grid of 4 points by 4 points ?

I'm thinking if I could do this I could mold some of the more difficult surfaces I need by point pulling ?

If not square is there another way to create a circular surface with specified number of points.
