As well as providing you with ready-to-use symbols, the Symbol Authoring option gives you the flexibility to create your own.
There are several ways to create your symbols. You can:
Draw a shape from scratch using the drawing tools, such as the line, rectangle, ellipse, and freeform tools.
Merge a shape with other shapes to create a new, unique symbol.
Revise an existing symbol.
To use this functionality, you must first install Symbol Authoring using Add-Ins on the Tools menu. If you do not see the Symbol Authoring add-in listed in the Add-In Manager, you must run the Custom setup to install the Symbol Authoring option.
