Patterning

This section explains and illustrates how to create various kinds of patterns on Sheet Metal parts.

Create rectangular patterns: select the element to be duplicated, set the patterning type, and its parameters, and the reference direction
Create circular patterns: select the element to be duplicated, set the axial reference  parameters, the reference direction, and possibly the crown definition
Create user-defined patterns: select the element to be duplicated, and the positioning sketch and anchor point 

To know more about patterns, refer to the Part Design User's Guide.
