Hello,
I am trying to export an IFC from a very simple model (for testing purpose) from Revit 2017. I want to test what is exported exactly in order to use it maybe for energy analysis outside of Revit. So I export an IFC 2x3 Coordination View 2.0, which seems to go well. It gives me a 6kb IFC file. Then I try to simply reimport in within Revit, and there, I got nothing. No error message, but it's like the IFC is empty...
I am not expert in the IFC formats, but from what I've read, the Coordination View 2.0 should at least contain the walls, roofs, etc.
So, what am I missing?
Attached is my rvt file used for export. It's just 2 small rooms.
I am able to open IFC files found on the web though..
Thanks a lot for any help,
Arnaud.
PS: Furthermore, I have download and installed the Autodesk app for IFC export. Doesn't seem to change anything.
Gelöst! Gehe zur Lösung
Hi Cenaero,
Open the IFC file in a text editor
And save it as .TXT with ITF-8 encoding option.
Hope that helps,

Hello,
Thanks for the answer. I tried this. I guess you mean UTF-8 ?
I did that, and saved as ".ifc" (if I save as ".txt" I can't see it when I'im in the import IFC window of Revit). I still got nothing..
Attached is my ifc file. I zipped it because apparently this forum doesn't accept ".ifc" files as attachment (seriously..?).
Thanks,
Arnaud.
I saw, from the text file you were using QuantityTakeOffAddOnView, can you do just the default IFC2x3 Coordination View 2.0? Not sure that will solve your issue.
FILE_DESCRIPTION(('ViewDefinition [CoordinationView_V2.0, QuantityTakeOffAddOnView]'),'2;1');
Also if you use 'export only element visible in view' and if the current view has nothing in it, nothing will be exported.
@Anonymous, I'm actually curious, what option, in the IFC Export UI, did you check to get the 'Quanity Take off view'?
Because I don't see that in my UI (Alternate UI 16.6.6.0.0)
Thanks.
Hello,
Thank you for your suggestion. I re-did the export, using the "classic" Coordination View 2.0, which shouldn't be limited to elements visible in view (but I made sure to export from a 3D view where all elements were visible). I still have the same problem.
Hi,
I found what was wrong. By default, in the IFC export Classes options, walls are... not exported instead of being exported to ifcWall. I find that quite surprising, but.. yeah.
Cool... If curious, I've used Jon Mirtsch's import class map before. https://github.com/jmirtsch/RevitIfcImportClassMap
