    Area Percentages

    Hello all!
    I'm a bit unsure if this is possible, but I thought i'd ask. I have a project in schematics and have a BASIC room schedule. basically it shows the room type (circulation, public, staff, etc), the room name and the square footage. so for example say the public corridors are 300 square feet total and equal 40% of the building's square feet. i'd like to have a column with the square footages and next to that a column stating the % of the building's square footage (in this case 40).
    i thought about using a formula, i just can not figure out how to get the building square footage in the formula other than typing it in. this would be problematic because if the overall changes, this will not update in the formula.

    Any ideas?

    Thanks so much in advance.

    You arent going to get a Room schedule to read the total SF of the building (without a really expensive API Addin :rollseyes, they just dont have that link built in to them. But there are ways you can make it easier on yourself. Make a Room Key Schedule, with Key Name, and Building SF. Type in the building SF. Set every room to that Key. Now, when the building SF changes, you ONLY have to change it in the Key (one field, in one schedule) and all of the rooms will update.

    Use an Area Plan to get Gross Square Footage (no, you cant tie it to the Rooms or the Room Key) and use that to validate your manually entered parameter.

      I understand that you have a basic room schedule, and you want to add a column for percentage of each type of room in relation to the total area of all the rooms in the building, is that correct? If that is the case, from the Room Schedule, from Sorting & Grouping tab, sort the schedule by room name or department, depending on which fields you have. Remove the "itemize every instance" option, and check "Grand total". From the Formatting tab, check "calculate totals" for the Area column. Then, from the Fields tab, click on Calculated value, and set up a new field, such as "% area", as shown in this image:

        That method will work, provided youre okay with considering the Room Tally of SF as the SF of the building. Keep in mind that Rooms dont account for the wall volumes between them, unless you tell Walls to bound at Wall Centerlines. But if you either use wall centerline, or are okay negating the volume of the partitions, Alfredos method is WAY faster and less work.

        We- unfortunately- need Building Total to include vol. for the partitions, and rooms to be to faces.
