can any one tell me where I can get some free electrical, plumbing, and hvac lines for my floor plans. More specifically im looking for lines that represent various electrical wiring, hot and cold water, piping connections, heating and air conditioning connections, etc... .

If you are using DataCAD version 11, make your own. Just draw what you want the line to look like using text if you wish and use the 'Create Line' tool in the 'Line Type' menu. Experiment with it until you get what you want.
