How to use the ArrayPolar, ArrayPath and ArrayEdit Commands
The old Array command is a powerful way to make many copies in rectangular or round patterns. But the result is a group of independent objects, and so the arrays cannot be edited except by erasing and starting over. To the rescue are associative arrays, in which the elements of the array can be interactively adjusted during their creation, as well as after the arrays are placed in the drawing.
Interactively adjust elements of the array during their creation
This video shows you how to use the ArrayPolar command to interactively create and modify polar arrays; the ArrayPath command to place objects along a path, such as a spline; and the ArrayEdit command to change the array after the fact — including replacing individual items with another object.
