tool that turns tedious Pro-E tool that turns tedious Pro-E drawings into something very drawings into something very simple. simple.

Technically, the Pattern Tool makes Technically, the Pattern Tool makes parametric copies (called instances) parametric copies (called instances) of an existing feature (called the of an existing feature (called the leader). leader).

UseUse The pattern tool is The pattern tool is

very helpful with very helpful with creating a grating of creating a grating of some kind, for some kind, for example, one with example, one with hundreds of holes. hundreds of holes. Figure 1 illustrates Figure 1 illustrates the use of the the use of the pattern tool to make pattern tool to make the holes in the the holes in the part. part. Figure 1. Pattern ToolFigure 1.
