Hello. How can I change the color of connection points in Visio 2013? Currently they are gray and not really differ from the shape lines.
Is it possible to change the size of the connection points ?
There's nothing I know of that can change this.
I don't know of any way to change them. They've gotten really bad in Visio 2013 too!
I wrote this utility a few years ago which places shapes over connection points, so that you can see where they are, what type they are, and in what direction they point (if you are using the advanced "2D glue" features of connection points.)
It uses VBA macro code to get the job done, so you have to be comfortable with that.
