I have over 30 years experience of CAD for printed circuit design and circuit layout ( Daisy Boardmaster, Orcad, Protel, Altium etc. ). I have now been asked to use Autocad for drawing up a companies circuit diagrams.I have used Autocad and Autocad Lt for mechanical drawing but have until now, never used it for electrical circuits. I would be grateful if somebody in this newsgroup could direct me into finding any free already compiled libraries for electrical circuits, I am looking for analogue and digital component symbols ( motors, switches discretes as well as logic symbols . ). I do not know which version of Autocad they will expect me to work with, can I assume library items ( blocks ) created in say version 14 will work in Autocad 2000 or will there be a problem in this area. I would appreciate all the help I can get so as to adapt as smoothly and painlessly into this work, thanking you in advance, I look forward to any information you may offer me.
