About Schematic Diagrams

You draw schematic lines just as you draw regular lines in AutoCAD
to help you. You add schematic symbols just as you add entities in AutoCAD, using an insertion point for
placement and a rotation angle.
However, schematic lines and symbols are more powerful than AutoCAD lines and objects because they
recognize the connection points built into each schematic symbol, enabling you to create an intelligent
building system diagram.
Connecting a schematic line to a schematic symbol
You can assign systems to schematic lines and symbols. Schematic systems store properties that remain
constant for all lines and symbols within the schematic diagram. They enable the lines and symbols in a
layout to act together as one by maintaining the same look and feel. For example, a layout of schematic
symbols and lines can represent a mechanical air supply system, an electrical power supply system, or a cold
water supply system. New lines and symbols inherit the current system's property defaults, such as layer
and color, providing a consistent method of drafting the schematic diagram. For more information, see
