Electrical IEC 617 Symbol Library:
Version 6.5 of the Electrical IEC 617 Symbol Library contains over 620 symbols, consisting of the majority of symbols contained in the following parts:

Part 2 (Symbol Elements)
Part 3 (Conductors and connecting devices)
Part 4 (Passive components{resistors, capacitors, inductors etc})
Part 5 (Semiconductors)
Part 6 (Production and conversion of electrical energy)
Part 7 (Switchgear, control gear and protective devices)
Part 8 (Measuring instruments, lamps and signaling devices

Since the IEC 617 Standard is metric, all symbols have been drawn to fit on ISO sized drawings. If required, the symbols can be inserted into ANSI sized drawings and then scaled down using a scale factor of 0.05. Brief descriptions have been assigned to the symbols. The symbols are accurately drawn on Layer 0 with a snap value of 2.0 and a grid setting of 8.0, for use with Metric sized drawing sheets. All symbols are accessed from pull-down menus and icon dialogue boxes. When possible, brief descriptions have been assigned to the symbols.

Add-on menus are provided for use with AutoCAD R13.c4 to 2009, and AutoCAD LT95 to LT2009. These menus are preferred, since they do not interfere with any prior menu customization and toolbar settings. Versions of AutoCAD and LT prior to AutoCAD R13.c4 and AutoCAD LT95 versions, are no longer supported by CADSYM.
