Shortest distance between two skew lines

Derived from this thread (Angular Dimension Tool - #8 by slbaumgartner and quoted text) I was thinking whether and how SketchUp could “do the math” for me with two skew lines (guides) from two 3D edges to give me the location and length of the shortest distance.

For given example (image) it seemed to do the trick quite well:


This is already in the API. :+1:

I’m quite happy to do this with SketchUp’s native tools that are understandable (I hope and guess) to all of us. That was my challenge.
I’m sure that a plugin could be written to wrap this challenge into a general approach. But to be honest, I couldn’t tackle this with Ruby. You may if you wish.
