A Symbol is a pre-defined symbol that may be assigned as an attribute of any Point item. Then, whenever the Point item is drawn you see a copy of the Symbol. The Point item can optionally store information that scales and rotates the Symbol.
Symbol objects are stored in Named Object Libraries. There are always some pre-defined Symbol objects that are used for some datasets (e.g. OS (GB) Land-Line 1:1250, 1:2500, 1:10000 files).
Once a Symbol object has been defined in a Named Object Library, it is very efficient for the computer to reuse it over and over again in drawings. So if you often use common symbols you should consider defining your own Symbol objects.
