A frequent, time-consuming Revit task is manually adjusting the upper limit of rooms. This problem arises because unless you are diligent as you place rooms by setting the upper limits correctly, rooms will default to an unbounded height of 2438mm (8 feet). This inaccuracy can prove frustrating when you want to apply a colour scheme in section.
However, with a simple Dynamo script, this can be automated via a single click. To do this, you’ll need the ‘Room.AdjustUpperLimit‘ node as part of the BVN package available via the Dynamo Package Manager. Simply connect a Boolean node to the input and run.
All rooms will be updated to have an upper limit based on the level above and with a 0 offset.
