It's a little hard for me to follow it since it is in French, but as far as I can see it has some options for "horizontal" and "vertical" and not for x= y= z= like you wrote previously?

I still could use a clearer example from an existing program to really understand...

It's possible that these options that you want would really be more applicable to a 2D-specific drafting program rather than the kind of 3D focus that MoI has.
