It always good to have many ways and different choices to obtain something ;)

The use of the relocate cline with constraint requires a little mind training !
To click on a vertical for have an horizontal is a little pertubating :)
And the fact that that the cline can be at any place around the first click also ;)
And the carreful of "single click" without release is a little frightening :)
But when you have well understand the manipulation, it's very easy!

It's for people who take the time to draw
The "relative system" is for speedy people:)
