Hi Martin, sorry I'm not sure if I'm understanding what you're asking about there - what is the "d(n) constrainer" ? You mean setting distance constraint that allows you to control the length of a line as you're drawing it?

It's somewhat tricky to stick too many extra things inside the right-click repeat mechanism because it can break other workflows. Like for instance if distance constraint itself repeated, would you then have to instead manually trigger the line command itself if you wanted to draw 2 lines in a row?

It could be possible to set up a script on a keyboard shortcut that would set a constraint of a specific value, if you need to use a specific distance value a whole lot that could be a way to repeat it quickly, let me know if you would like a script that would do that.
