Hi Ranjan, A similar application is normally being used in CAM programs using surface milling. In that case, a so-called ball-nose cutter is constantly in contact with, and moves over the surface. What is being used sometimes is a so-called offset surface. Offset being the radius of the cutter. So, you need to create the surface and also an offset-surface. If you have that offset, it will not be too difficult to follow all the points lying on the surface, perhaps within a certain tolerance.
However, you still need to create the surfaces. Perhaps trying C or JUN as Mattijs will be the best solution.
