I understood very clearly and shared with you my thinking on this.

I did not have an example to share with you; I did write one but I will not be sharing that.

The first thing I did was start considering this without looking at other code.

I considered the “midpoint between 2 points” and wrote a general function to place a point anywhere between the two points A and B along that line.

From there I was able to move that point anywhere along a line between 2 points A and B in 3D space:

And now I am having fun with it!

Your example inspired me and I created my own project for this from scratch. Thank you!
