In MathTeacher's picture, the locus of rotation points that would make the lines co-linear is a line through points A and B. Using any rotation point...

And the original post had had a goal of finding the best-fit rotation point. That seemed to be more important to him than finding the final position ...

Is that absolutely everything I'd need to run Opus sessions, except a tripod and a computer? How is the data transferred?

If the goal were only to rotate one line to become co-linear with the other, I think there is a continuous locus of pivot points available, not just y...

Your two pivot points will make the lines co-linear, but only pivot A will make their endpoints near coincident, which I understood was the goal. Furt...

Isn't there a Canadian equivalent to OPUS? You say you were given UTM values. How were those determined? A "calibration" means you tell the machine w...

Or was that 0.134 difference, so moved points 0.067 outside? I blundered somewhere, not sure which.

After thinking about it for a while, I realized that the least squares solution would be to put the moved point on a straight line with 3 and 14. Sin...

I don't think you are going to find an exact solution unless the lengths of the lines are some magic relative values that work with the difference in ...
