Grid scan will project a grid onto the surface with reference to the CAD position in graphics display, but will not follow the surface boundaries for an even distribution (like on a curved surface)
UV scan will create evenly spaced points for your defined grid, but only in a rectangular-shaped area, so if the CAD surface you are trying to populate with points is oddly shaped this method might not work too well.
Manually placing points with John's method above can be a good all-around option if these two won't give you the results you want.
There is also setting up datum points in the DESIGN SOFTWARE (solidworks, CatV, etc), and bringing them in via iges, step, etc. and selecting them with the auto-vector dialogue open.
Oh, and you can also use several BOUNDARY scans with increasing offsets from the boundary edge to create a grid-like array of hits.
