This is typically one of the first "modelling power tips" new tool users learn. Note that:

- If the dragged-out Property or Port is not already the end of an Association, a new Association will be created.

- If the symbol for the dragged-out Property is not already present on the diagram it will be created (otherwise an Association line is simply drawn to the existing symbol).

By default, the Property or Port will "vanish" from any listing compartment on the Class or Block symbol, unless you tweak this power setting (which is only available in 'All' symbol display mode, not even 'Expert' symbol display mode). It's highly recommended that you explore this:

MagicDraw/Cameo: If you want to show a Property or Port listed both in its corresponding compartment on a Class or Block symbol and as the end of an Association in the same diagram, set the display option Show Association Ends As Attributes/Ports to 'all'

This "drag-out" feature in a sense works together with this "drag-on":

MagicDraw/Cameo: You can drag a Class symbol onto a Class symbol (in a Class Diagram) or a Block symbol or ValueType symbol onto or Block symbol (in a Block Definition Diagram) to create a new part property or value property
