Hi Tomol, hope you don't mind but i would be very interested in any form of IEC symbol list or database. I've had to draw most of mine from scratch so far.
A great library of standard electrical symbols is available for AutoCad. The symbols are located in a pull down menu. All symbols are attributable and are drag and dropped into Autocad from a thumbnail preview screen. This is a must for AutoCad users. For more info you have to email accudraft@comcast.net
