Hello everyone, 

I would like to use macros to automatically array teeth of the same size on a closed body surface (example in the following picture). How can I do this?

My current ideas are: idea 1. Using slicing tool to get many reference planes and intersecting lines with the basic body, then sketch the teeth on each layer (costing much time, how to automate?). Then the teeth can be arrayed by the curve-driven pattern tool along the intersecting lines.

Idea 2. Selecting an initial point on each face and then arranging it according to the distance of the points on the intersecting line (not sure if this is automatically feasible).

I really appreciate it if someone can help me. Thank you!
