The Laser pointer told you how far it was shooting.
I meant for building.
He doesn't want the distance in the way you're thinking, he wants something that tells him how many 1x1's there are between that point and the other point. In essence if he's building something that's apart and wants to connect them this will tell him the length of brick he needs.
That is what I was thinking?
What if you want to measure diagonally?
Measure complete:North: 30South: -30East: 9West: -9Up: -104Down: 104
This would make a build, like equal on both sides.
