Selecting Projects | 5 6 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 Inserting wires Trimming wires 7 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. Menu Projects Project Project New/Existing 2 In the Project dialog box, Project Drawing List section, double-click demo04.dwg to open the drawing. 3 Zoom in on the upper left corner of the drawing. 4 Click the Add Rung tool.

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 components Inserting parent components Inserting child components Generating component reports 11 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.

From a small set of library symbols, hundreds of PLC modules can be built on request. This method allows the module to conform to the underlying ladder rung spacing, so you can add spacers and break the module at insertion time. About PLC modules Inserting PLC modules Removing ladder rungs Using Fence Insert 37 About PLC Modules AutoCAD® Electrical generates any of hundreds of different PLC I/O modules on demand, in a variety of different graphical styles, all without a single, complete I/O module library symbol resident on the system. Modules automatically adapt to the underlying ladder rung spacing, whatever that value might be, and can even be stretched or broken into two or more pieces at insertion time. Inserting PLC modules AutoCAD Electrical builds a PLC I/O module as it is inserted. A PLC module is selected, the location is picked, and the module is constructed using a small set of library symbols. To insert a PLC module 1 Open DEMO10.dwg, if it is not the current drawing. 2 Click the Insert PLC (Parametric) tool.
