Object Editing: Duplicate

Any shape or group of shapes can be duplicated by hitting or by hitting Command+D or Control+D on your keyboard. 

Duplicate in Place

Use ‘Duplicate in Place’ either by using the duplicate button group at the bottom of the canvas, or use shortcut Control+Shift+D or Command+Shift+D.

Duplicate in Place is great for creating designs or patterns that will share some alignment - like concentric circles or stepped tenons.
