Copying and duplicating model elements
You can either copy or duplicate model elements across whiteboards. Copy creates a new instance of the same shape. Duplicate creates completely a new shape.
Procedure
Copying an element:
A new instance of the shape is created and any change to the copied shape is reflected in the parent shape as well and vice versa.
Duplicating an element:
The duplicated element is new and is independent of the parent shape.
