I got an IFCexport from Revit and hoped to turn off one floor slab to expose the storey below with walls an some details.
Unfortunately all floor slabs in a Revit model is exported to same ustn-level.
Anyone know of some trick I can tip the Revit guys so the export puts the different floor slabs in different ustn-levels.
(thought I posted this a few hours ago - if the appearance is delayed - sorry for taking bandwidth)
Is my wording above correct 'in' a ustn-level but 'on' a level in a building?
I don't understand the question, slabs are usually on one level, as are walls and columns.
We define the structure of our files.
Cannot revit use xref and place each floor in a different ref file?
I wanted to add to Andreas's thoughts.
For us slabs - yes - on on the same levels fut different ref files. (ex., exterior walls, 1st fl, 2nd fl, 3rd fl, stairs, people, trees and veg, roof canopies, exterior, etc.)
This controls the file size and what we are working in. It speeds the machine this way and speeds BV's as I can limit files they are using. It also helps you control the output as questioned in the original approach.
I know Acad Arch can do this to with some coaxing by us. I though Revit could use xref and do this, but maybe I am wrong.

Haven't tried that yet, but try to create a group which includes all elements, and then remove the objects you don't want to see. Now make a building view of that.
Sure Andreas, same part, dgs and ustn-level. But in ABD in different Models.
So I can turn off display for a slab in floor 2 to see floor 1 below. Or make floor 2 transparent.
In the ifc I've got all floor slabs are on same level.
But I discovered that the setting 'Ignore Story Containment' -if off- splits the geometry to separate files!
So, if the Revit file is done with correct settings, it seems I get what I want.

You are doing a File - Import ifc, not a file - open ifc?
We have stopped using the file - import, it takes an eternity for the import, and the file sizes are extraordinary large, compared to the file open method.
But I agree that the functionality to keep the structure of the model is very important, therefor we have also file SR to get that one implemented into the file open method.
