The NFPA library symbols are in inches. Use the Project Settings tab on the Project Properties dialog box to define the path for which set of library symbols you want to use for a particular project. If you start with a list of components for a project and you already know the part numbers, you can insert a component by selecting it from the catalog database.
Use the Catalog Browser palette to insert components from the catalog database. Use the search to find the catalog you want. The search values you use are also saved and can easily be used again by selecting from the search drop-down menu. The catalog information is placed on the symbol automatically.
You can edit the symbol further using the dialog box that pops up as soon as a symbol is inserted. If the symbol you need is not yet associated to the catalog number, you can open the icon menu directly from the catalog browser to insert it.
The symbol becomes associated to that catalog number from that point on. If it is a catalog value you plan to use frequently, add it to the favorites. The icon menu lets you insert a symbol by selecting the symbol type, for example a NO push button, or 3-position selector switch. Once the symbol is inserted you can annotate it with descriptions, catalog information, and so on. There are different icon menus for the different library sets. Use the Project Settings tab on the Project Properties dialog box to define the icon menu you want to use for a particular project.
Each symbol can have a main catalog value and a number of what AutoCAD Electrical calls 'multiple catalog' values. Edit a component to add, edit, or remove catalog assignments. Some devices are represented by multiple symbols. For example, a relay may have a coil symbol and a number of contact symbols. AutoCAD Electrical uses 'parent' and 'child' symbols to create this relationship between symbols that represent a single device.
In the relay example, the coil is the parent symbol and the contacts are child symbols. When you insert a parent symbol, AutoCAD Electrical assigns it a unique tag value based on the drawing properties. The tag value is the identifier for a device. When you select the parent, the same tag value is assigned to the child along with any other values on the parent such as installation, location, and description.
