Thanks. I am not using PRO.
In case my question was not clear ...
I know how to scale Blue-Opposite. The problem is that when scaling long tubes (e.g. wires), the circumference is so tiny compared to the length of the tube that I have to do massive zooming just to be able and have my mouse movement select Blue-Opposite. I spend a lot of time trying to get the mouse to highlite Blue-Opposite as opposed to all the other scale options that pop-up as the mouse moves over the teeny-tiny end of the long tube. Of course zooming always works, but I spend so much time zooming and then unzooming on that tiny circle at the end of any tube.
Not sure how to do the RUBY code, though it looks like it could help. I'm a programmer, so curious to try it.
THanks
