IFC Import: wrong orientation of opening/window

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?

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?
