What is a Symbol?
A Symbol is simply a pre-defined image that can be included as an attribute of any Point item.
This means whenever you draw the Point item, you will see a copy of the Symbol. The Point item can optionally store information that scales and rotates the Symbol.
TIP: SIS Desktop 9 can reuse defined symbol objects over and over again in drawings thus improving efficiency. We highly recommend defining your own Symbol objects for frequently used symbols.
