Calculate full wall area when % of openings is less than a given value

[JasonLLINDNER]

HI revitiers

Is there a way to get Revit to calculate wall areas as follows

1. if percentage of wall openings, Windows, doors in the wall is less than 10% of the total wall area => use/schedule full wall area 
2. if percentage of opening, Windows, doors in the walls is greater than 10% of the total wall area => deduct the openings from the total wall area i.e.: schedule area = total wall - total openings

Using Revit 2016

I assume it can be done but not automatically. You would need some calculated values, additional columns in the schedule, and some manual entry.

I think there used to be a addin some couple of years back which does something similar but I can't confirm for sure...I've never used it as such kind of tasks were always someone else's headache lol

You can check on Autodesk Exchange if no feasible solutions are offered here

i can think of Dynamo doing such tasks easily but I'm not sure the trouble is worth it

Found the app you mentioned on Autodesk App Store and it does what is required...thanks

Hi what was the name of this app?

This is an old one!! I believe the addin was roombook/areabook ... later I think in 2014 became part of the Subscription package; however, had to be installed separately at the time from Autodesk App store...later moved and made available on account management downloads section or through the desktop app in 2017/2018 ... today it is an integral part of Revit like most addins which Autodesk took over.
