Pave and prongs on Sub D and Polysurfaces

Trying to layout and boolean cutters/prongs into solid curved surfaces.
I find good pave tools in expensive plugin programs (crossgems etc) but I only am in need of the pave function.
Any suggestions for doing within Rhino 7/8? Plugin?
Have not used Grasshopper but will learn if pave works in this. Pave plugin for this?
Thanks!
