The library includes bells, buzzers, horns, signal lights, capacitors,resistors, disconnects, fuses and circuit breakers along with pressure, limit, float and pull cord switches. Relay coils, contacts, timers, and a wide range of 1, 2, & 3 pole combination starters are included. Induction and commutator motor symbols, transformers, logic elements and a small selection of solid state devices and a wide range of selector switches, complete with optional camtables, are provided. All symbols are accessed from pull-down menus and icon dialogue boxes. When possible, brief descriptions have been assigned to the symbols.
The symbols are accurately drawn on Layer 0 with a snap value of 0.2 (2.0) and a grid setting of 0.4 (8.0), depending upon the choice of Imperial or (Metric) sized drawing sheets.
Alternate partial menus are provided for use with more recent releases of AutoCAD, starting with AutoCAD R13.c4 and AutoCAD LT95. These menus are preferred, since they do not interfere with any prior menu customization and toolbar settings. They can also be used with other Autodesk products, such as Mechanical Desktop.
