A video about : AutoCAD Electrical - Creating your own component category
As a default, AutoCAD Electrical has a schematic library and a single line diagram sub-library. This enables the user to place two different representations down of the same component. However the user is able to create their own component category and for this to be listed as a filter in the reports. As an example a motor may be shown in the detailed schematic, the single line diagram, the block diagram and the circuit diagram thus meaning four different representations of the same component. However when producing bills of materials you would only want one item listed.
