Originally, I was using it to find the radius of the sphere I needed to subtract
from a (rounded) box to make a laptop keyboard key.
It's also useful for making any concave "cap" to a cylinder or a box.

I also needed this, or a variation thereof, to find the center of a very large
circle in order to model a sheet metal / screen development for making a
replacement globe for a vintage dual-fuel lantern I have.
Modeling software is great, since you can get the curve you need using the
actual center, since the entire workspce is virtual, but when laying out such an
arc IRL, one needs alternative approaches when either the center is inaccessible
or the radius makes scribing the arc wildly impractical. There are several
such ingenious approaches.
