The only other thing that's a bit odd with doing this in a 3D modeling program is that there are 3 different possible directions to space things in - spacing between the edges in the X axis direction, the Y axis direction, and the Z axis direction.

Any idea of how you would want to control which of these directions would be used?


Maybe instead of using a fixed direction you should draw a line and the spacing will be done in the direction of that line.
