This started out as an Array Copy along a path query. One of your threads pointed me towards the _measure command which in itself was a revelation... Thanks for that useful information, I think I could use this command a lot..

However, when I try to copy a rectangle along a spline, the command insists on aligning the rectangle against the line using the shortest side. I want it to align using the long side. I've tried re-writing the block with different insert points to no avail.

Is there a subtlety I'm missing when using the _measure command or when writing the block ?
