Hello @Tim Edwards, I am trying to make array of an instance using command: array 4 1 . It gives me the array of 4x1. Now i tried to make spacing between the instances using command: "array width 30um" and "array pitch 30um 30um", it does not create spacing, shows msg "Unimplemented function." How this spacing commands work to create spacing between insynaces in x and y direction?

array pitch

is only diagnostic; you can use it to get the array pitch but not to set the array pitch. The array pitch is always set by the bounding box. So you would need to

box size 30um 30um;  array 4 1
