Can't import IFC file

I see that SOFiSTiK 2022 can import IFC2x3 and IFC4.

SketchUp Pro 2021 can export both versions.
But… both IFC exporters do not yet export all necessary information for a smooth software independent workflow / collaboration.

To make an better IFC 2x3 export you can use the IFC Manager extension.
You can download it from Github using the link in this post.
