Abstract
This chapter introduces the concept of creating different types of arrays to students new to AutoCAD. A polar array is a collection of objects around some common point arranged in a circle. An example in architecture is a group of chairs arranged around a circular table. The idea behind a rectangular array is not fundamentally different from a polar one. One simply draws one I-beam column, makes a block out of it, and arrays it up and across the appropriate area. The first thing to do is to draw a convincing-looking I-beam. Because one needs actual distances, one cannot just randomly draw any object. The path array, a feature newly added in AutoCAD 2012, involves creation of a pattern along any predetermined pathway, of any shape, as opposed to a strictly circular or linear one. The path array has its own Ribbon tab, which is revealed by selecting one of the elements in the array. Its menu shows up as one hovers the mouse over the grip.
