How to create these 2 shapes
Hello fellas,
So I created the horseshoe below, and I need to align the circles with the same space to the uneven shape, what is the best approach?

I also want to replicate the figure in red, but the flag effect does not do it with a triangle and it only gives me 2 curves. Any trick to make it smooth from wide to narrow?

Appreciate your help and time in advance!
