I spent a bit of time going over the basics using auto cad on it's 30 day license but that is set to expire soon, tomorrow I think. http://www.we-r-here.com/cad/tutorials/index.htm
is what I used.
This program seems to be exactly what I was asking for, not sure if there are other alternatives out there but so far this seems to be exactly what I need.
I would like to have a cad system with all the bells and whistles but I don't think my company is going to purchase autocad for me as we already have 3 cad techs.
This is a picture of a junction box for a 34.5kV Junction box as part of a collection system for a wind farm, I work for a wind energy company, it's for a paper I am working on.
