TIG and Chris
Thanks for the replys!
I did not make myself very clear sorry. 😐
I have created a spread sheet that solves the problem for my use but did not put the logic for the five cases in it. I am not a ruby programmer and thought a plugin would be more useful for the number of folks who have posted this question in the past plus thinking this is a capability any 3d model program should have. Given the fact the ref URL has c, lisp, etc code examples I thought it may be easy to create a plugin. I'll leave it up to your expertise if that is a reasonable thing to do. If have found doing this manually and using the interpolation scheme Jeane Lemire ( I think ) gets problematic for this case because one winds up trying to interpolate in two dimensions.

The five cases are from the ref and the only ones I can ID also. The range of solutions for solving the quadratic equation in the ref give you the info( sign and magnitude of u) to make a decision on where the line segment lies and if there are intersections and how many.
One wants to keep the line segment for L1 the same and you can either rotate or do an x,y,z move of L1's vertex as I did in the skip. I tried solving the problem for rotation( theta and phi) using the standard form of the line in space( intersection of two planes ) I get a trig equation in two variables I cannot reduce by the standard approaches.
Thanks again !!
i did the same once
and after the integration of the Free Download Manager once again , it happened again,
i discovered that saying no to the Free first dialog, and once looking like closed the download, it suddenly appears the option of saving normal in Windows.
😄
The question was that the Free Download saves it as php or something, the way to do is to change in the options , the name to : --whatever-- .skp
