To Create a Point Symbol

Draw the elements that will be part of the point symbol.
Select or fence the elements. If you use a fence, the Fence (Selection) Mode is ignored; only elements completely enclosed by the fence are used.
(Optional) Use the Define Cell Origin tool to define the point symbol origin.
In the Components list box, select any point symbol component.
The controls for working with point symbol components are displayed.
Click the Create button.
The Create Point Symbol dialog opens.
In the Name field, key in a name for the symbol.
Click the OK button.
If you skipped step 3, enter a data point to define the point symbol origin.
Note: If a point symbol with the same name is already present in the library, an alert box containing that information is displayed, and you are given the option of overwriting the existing point symbol or cancelling creation.
