    We agree you think it can't . I'll trust your judgement on that, I don't have a clue what Business Class occupancy for IBC is.

    Uhhhh okay. By your own admission you're manually copying data around, which is what I said it would take to do it correctly, without the API or dynamo.

    So rock on with your *you think it cant* stuff. You don't even understand the problem were talking about solving, if you aren't using that code (no offense). So yeah, that's what I thought.

    Okay, ill bite, since you DID successfully get it to "do a calculation based on the total of something."

    The way you did it is very clever, in which you've created one extra object (a placeholder, lets call it) to use as a *vessel* to hold the data and do the REAL calculations. Im a bit perplexed with how you're going to get a placeholder object for Rooms or Areas, to do your calculations, as i only see a few viable options:

    1. Youre going to place dummy rooms or areas somewhere in the model, to hold on to the *schedule data,* which i could actually see working out quite well, sans the train-ability aspect of it. (Standardizing where it goes, why its there, what its named, what its name is (0 in the number column, etc)(which i dont think would be that bad at all, but....)

    2. Instead of having a dummy placeholder, you're going to strip the portion of the IF formulas out of the last CV's formula field, and replace it with an If statement that iteratively steps through all possibilities for the "number" column (which is where you would have to have occupancy Classifications that drive OLF and all those things). This would end up meaning that the other columns (volume for number=3 +1, %volume for number=3+1), are all going to have the massively long IF statement formulae in them.

    But it IS pretty badass, that you got that to work. Matter of fact, i think the iterative IF statements in a badass area scheme or Room scheme template could work.

    (Okay, forget item 1 above... Because i dont think you need the placeholder 17th object to do the math at all, as this seems to work).

    That gets even more interesting, since you might not need to use Grand Total at all. I moved the formulas to use Number instead of Grand total. thats what we would have to do for Occupancy to work, since each has to calculate based on the totals of its Occupancy Classification, and the only thing that uses the total of the entire building is Doors and Exit Width.

    Hmmm.

    Shoot me an email, if you dont mind. Im going to make a quick video (tomorrow or monday) of whats buried in my (previously defunct) occupancy calculations.

    oh, and ****... I havent said it yet: I was wrong.

    Thats banging stuff. Im still not sure the same technique can work with the occupancy calculations instead of volume, but off the top of my head i cant see a reason it wont work.

    Reviving this thread:

    EKKONAP is a f***ing genius. After reverse engineering what he created, i have this 100% working for CORRECT Plumbing Calculations per IBC 2012, without needing any External Intervention to move the Totals for each Occupant Load Factor, in to a field that can run calculations.

    This is an Epic Win.

    I've had this on my to-look-at list for awhile. Since you posted, I figured now is as good a time as any!

    I'm assuming you have some rather large if/then's and quite a few extra parameters. Would that be more or less correct?

    I think I see what Ekko is doing. Smart.

    Not at all. 5 additional calculated values, and all of the formulas are short enough to type without expanding or scrolling the formula box.

    Does this mean that I finally get to see one of those IBC schedules?

    Yessir, it certainly does! Im getting it finished up as we speak. Im just having to go trhough a few more hoops since i need to do your trick to get the totals in to the field, then i need to have other fields that work backwards AFTER the calculation performed on the totals, so we can use schedule TOTALS to show all of the areas together.

    What were trying to achieve, is compliance with the IBC2012 Plumbing Occupancy requirements:

    Chapter 29 - Plumbing Systems

    You can use completely STANDARD Revit calculated values, until you get down to "Business and/or Assembly" occupancy types, where there is a "Base" requirement and then a "Base requirement max" where the standard shifts to less fixtures per person. The reason you cant do it without your trick, is you need to perform that calculation on the TOTAL area of the Business areas in the building. Putting it in a normal CV will perform the "1 per 40" for EACH SPACE that is a Business Space, and the numbers get wildly out of hand.

    But yes, its all working now. Video to follow!
