The diameters of min and max are responsible for the size of the objects in the pattern; then smaller the value, then more objects will be and the slower the script will generate a pattern, it is worth to remember. Tick NoResize will allow us to keep the current sizes of the source objects out of the artboard.
Offset min and max are responsible for the centrality of objects to each other. Then bigger is Offset then more the objects are located is wider, and vice versa. As in the Light version, we can use negative values, which gives a maximum approximation of objects or overlapping each other.
The principle of operation of a script built on the so-called auxiliary circles, for which we set the diameters and offset values. In the current version Pro, we can see these circles if select the check box Show circles.
