Hi, I have a simple IFC-file (see attachment) that comes from a different application.
The file contains a wall (with a window) that, when opened in Revit gives a wrong orientation of the window.
Here is the IFC-file opened in BIMvision, this visualization is correct and I expect the same orientation of the window when opened in Revit.
IFC-File opened in Revit (2025):
The window is rotated.
When linking the IFC-file, Revit correctly shows the window.
Why is there a difference when linking the IFC-File in Revit and when opening the IFC-File in Revit?
Is the IFC-File incorrect?
I observe the same (wrong?) behavior in Revit 2023, 2024 and 2025.
I need to open such IFC-Files correctly in Revit because I want to modify and extend the model.
I have seen a couple of similar issues
Window rotated in Revit · Issue #549 · Autodesk/revit-ifc · GitHub
Does the following have an influence?
Export IFC changing Coordinate Base to Project base point.
What do you mean with "Export IFC changing Coordinate Base to Project base point."?
I get the IFC-File from a different application... I do not have impact on the coordinate base during export
Is there a (hidden) Revit-IFC-Import setting?
Just for your information, I checked in Revit 2024 and 2025...
its linking correctly.
Yes, i observed the same behavior (in Revit 2023, 2024, 2025).
But when opening the IFC-File, the orientation of the opening/window is wrong.
What is the problem there?
Has anybody an idea how the IFC-file needs to be modified so that it can be opened correctly in REVIT?
