    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!

    That has always been my line of thought as well. /shrug

    Here in France the ground level is called Rez de Chausse, and the floor which is above is called N_1, whilst in latin america the ground floor is called N_1 (level 0.0) and the floor above it is called level 2.

    Honestly, i wouldnt have any issue with calling the Ground level GROUND LEVEL, and all levels above as Level +1, Level +2, etc. My undergrounds are similarly called U1, U2, and U3, for underground. So it would actually make more sense.

    But Ground gets tricky, or- at least- needs to sometimes be considered as *Main ground* as projects with more than one Ground Level are pretty common.

    I wouldnt slay dragons over the issue, but i wouldnt be against changing that either. But the logic behind the 100' thing... Just doesnt hold water, imvho.

    I was playin with annotation strategies using a “-“ at the beginning of each line as a separator and a colleague told me that was bad because it means negative and if I used it I was saying the annotation was negative.

    True story.

    Guessing he’d have the same view of negative level values. LOL
