Is there an easy way to have a geometric shape, say a box that has 1/2-point line thickness, replicated (mirrored) left to right on it's right-hand axis... so that the vertical lines where it's rotating from overprint each other EXACTLY? I.e, you don't have a vertical rule in the center that's optically heavier than all other rules in either box. I've a number of forms to be done and manually adjusting the horizontal positioning of these elements is quite tedious. When I use the mirror panel buttons, the objects abut -- they do not overprint on their common edge. Normally I'd set up a table, but the boxes all have rounded corners.
Try using the Move command (double-click the Selection tool) to open the Move dialog, with the Copy button. When doing that, move it the width of the rectangle but subtract the width of the stroke.
To make it easier to test, I made a 1" x 1" square with a 2 pt. stroke.
In the Move dialog, I copied the square "1 in - 2 pt"
Muchos gracias Stevenski! Next time your in downtown, Bensalem, PA USofA, stop in and I'll buy you a hoist or two.
