About Patterning
Patterning creates multiple instances of selected geometry instead of creating geometry repetitively. You can add pattern members in one or two selected directions. You can select geometry for patterning using manual and shape selection methods. The selected geometry can be patterned and can remain attached to nonpatterned geometry thus recreating rounds and chamfers at the attachment point if required.
