Hi,

My Revit model one large atrium in the middle which changes shape at each floor - its 5 floors high.

I'm creating and tagging rooms in the model and would like to create a room for the atrium.

I know I can be set to have an upper and lower limit - say Level 1 to Level 5, but is it possible to get the room to change shape on each floor?

I've attached a simple model to illustrate what I'm trying to do.

Cheers.

Ok, I looked at the model you sent and there are actually two issues at stake.

1: In order to get rooms to "fill" horizontally, their boundaries will have to encompass the largest space. I tested this by placing the room at Level 2 where the walls were farthest apart. I then moved the top and bottom extent of the room element to encompass the other levels.

2: In order to get Floors, Ceilings, and Roofs to "Bound" the room you will need to go to the Home Tab-->Room and Area Panel-->Area and Volume Calculations button. Make sure it is set to Calculate Volumes.

This will get you closer to what you are asking, but depending on the complexity of the room "shape" this may not be a 100% soultion.

Thanks for your reply.

With option 1 - would this not measure a larger area than needed on floors where the atrium is smaller?

How do people cope with this usually? This can't be an uncommon ocurrance? Do they just put room spaces in at each level perhaps?

We put rooms at each level where there is a floor area at that level and allow the "atrium" only area to be multi-story.  Think about different finish & elements on other levels.... They really need a different room name to account for them.

I agree with WWHub. The logical solution would be to make the overhanging area other rooms and allow the atrium to be a shaft like space that spans multiple levels.
