(image attached) The ability to move all points in a mesh both vertically and horizontally. currently I can't move a point beyond the limits of my mesh, so I can't get a cliff like shape.
I normally use meshes and slabs for preliminary massing (similar to sketchup) and if only I could choose any point in a mesh and move it anywhere along x, y, z than I think I could cover all basic architectural (non organic) forms. not to mention that my garage ramps would be simpler to do also.
