    Maybe it is a "Minnesota thing" Dave? This is the way I was taught to do it too but my professional experience is from Minnesota. i think I have since heard more opinions that it is weird than opinions that agree with it. I am still starting my projects and 100'-0" to spite them.

    As i mentioned, i dont do it *here* and so- when asked for my opinion i tell people i dont agree with doing it... But in reality, its one of the issues where:

    1. People claim there is an industry standard, and there isnt
    2. People claim *everyone is doing it their way* and they arent.
    3. People are making those claims based on what theyve seen, and what they want, not what actually is.

    I *like* mine to be at 0-0, since then the dimensions going underground are the actual value underground... But in reality, it doesnt freaking matter. I think -14' is easier to figure out than 86' (and then subtracting that from 100 to find out where the floor elevation is from ground), but at the end of the day its really not doing damage either way, as long as your drawings are clear about what the information is.

    That is a reasonable justification... I might have to change my mind on this... Dang it!
