i want to know tf ther's a way to scale my design in mack,
i always have to change the size of my design depending on the need of my clients, and all the time, i have to go back to my cad and cam program, and post again.
is ther any way to scale my design without going back to my cad and cam softwares?
thank you.

You can scale each axis with the scale at the side of the DRO, if you want X to be 10 times bigger you enter that in the box, if you want it to be 1/2 size you enter 0.5 etc.

i did it; i put 2 in that scale dro to make my drawing two times bigger, but it stays the same.
the default values of this dro are +1.0000, i changed it to +2.0000, nothing changed.
 

Hit "regen" to see the new size in the toolpath.
