All 3 of you used Revit to draw your singe line diagrams. Look at how different they all look. I agree with some of the earlier comments that stated Revit single line diagrams would only appease 1% of the people. Every firm does their risers/one lines different. Some draw from the bottom and go up through the building.. some put the switchboards at the top and go down. Other use lines to show a bus, others draw the actual size of the switchgear. There are way too many options for Revit users to be forced to settle on one format. Even though it is b**tch to update your singe lines and plans, I think it is still better than being forced to show your riser/one line the way Revit chooses. Just my oppinion.
