About AutoCAD Electrical
All of the AutoCAD commands and features are available while working on
AutoCAD Electrical drawings. All intelligence is carried directly on the
drawing using AutoCAD blocks with attributes and XDATA. AutoCAD
Electrical does not require any underlying database.
Learning AutoCAD Electrical
It is assumed that you have a working knowledge of the AutoCAD interface
and tools. If you do not, use the integrated Design Support System (DSS) to
access the online documentation.
It is also recommended that you have a working knowledge of Microsoft®
Windows NT® 4.0, Windows 2000, or Windows XP, and a working
knowledge of electrical design and schematic ladder wiring diagrams.
Using Help
As you work, you may need additional information on the task you are
performing. The AutoCAD Electrical Help system provides detailed concepts,
procedures, and reference information about every product feature. To access
the Help system:
■ Select Help ➤ Electrical Help Topics from the standard toolbar.
■ Click the Help button or press F1 within a dialog box.

Wires
In This Chapter
1
AutoCAD® Electrical treats AutoCAD line entities as
wires when the lines are placed on an AutoCAD
Electrical defined wire layer. These lines get tagged with
wire numbers and show up in various wire connection
reports. Two wire segments connect if the end of one
wire segment touches or falls with a small trap distance
of any part of the other wire segment. This connection
can be at the end of the other wire or anywhere along
the length of the other wire. AutoCAD Electrical
considers a wire connected to a component if the wire
end falls within a trap distance from the wire
connection-point attribute of a component.

About Wires
An AutoCAD Electrical wire is an AutoCAD line entity on an AutoCAD
Electrical wire layer. The wire layer for a new wire segment is determined by:
■ Wires that begin or end in space or begin and end at a component
connection point, are put on the current layer (if it's a wire layer) or on
the first wire layer AutoCAD Electrical finds in a layer name search.
■ Wires that begin at an existing wire take on the same layer as the
beginning wire.
■ Wires that begin in space or at a component and end at an existing wire
take on the layer of the ending wire.
Inserting Wires
You can start or end a wire segment in empty space, from an existing wire
segment, or from an existing component. If you start from a component, the
wire segment snaps to the wire connection terminal closest to your pick
point on that symbol. If the wire segment ends at another wire segment, a
DOT (block name wddot.dwg) is applied if appropriate. If it ends at another
component, the segment connects to the wire connection terminal closest to
your pick point on that symbol.
To insert single phase wiring
1 Click the Project tool to open the aegs project.
MenuProjects ➤ Project ➤ Project New/Existing
2 In the Project dialog box, Project Drawing List section, double-click
demo04.dwg to open the drawing.

Trimming Wires
After you insert wires, you may need to trim them. The Trim Wire tool
removes wire segments. You can trim single or multiple wires.
To trim a wire
1 Click the Trim Wire tool.

2 Respond to the prompts as follows:
Fence/Zext/<Select wire to TRIM>:
Specify the wire segment at line reference 404 between the two vertical wires (1)
Wire segments are trimmed back to a connecting dot, a component, or
completely if neither is encountered along the segment. Any connection
dots that are no longer needed are removed.
The trimmed wire resembles the following image:

Components
In This Chapter

An AutoCAD® Electrical schematic component is an
AutoCAD block with certain expected attributes. When
inserting components, you can use AutoCAD Electrical
tools to automatically break wires, assign unique
component tags, cross reference related components,
and enter values for catalog information, component
descriptions, and location codes.

About Schematic Symbols
AutoCAD Electrical supplies a schematic symbol dialog box for inserting
schematic components. Besides making it easy to find and insert the desired
symbol, it also triggers a number of additional features such as automatic
wire breaks, component tagging, real-time cross-referencing, and component
annotation.
Inserting Components
AutoCAD Electrical employs a parent/child relationship for schematic
components. A relay coil with a certain number of contacts is represented by
the parent coil symbol and the child contact symbols. When the parent coil
symbol is inserted, it is assigned a unique component tag. When the child
contact symbols are inserted, the child is related to the parent and the parent
tag is assigned to the child symbol.
Use the Insert Component dialog box to insert components into demo04.dwg.
Inserting Parent Components
Start by inserting the parent component.
To insert a parent component
1 Click the Insert Componenttool.
MenuComponents ➤ Insert Component
2 In the Insert Component: JIC Schematic Symbols dialog box, click the Relays
and Contacts button.
3 In the JIC: Relays and Contacts dialog box, click the Relay Coil.
4 Respond to the prompts as follows:
Specify insertion point: Position the component on the wire at line reference 403
near the neutral wire and click (1)
