Wrong site elevation in IFC export

[Chaikampa]

When I want to export an IFC model with local coordinates and rotation but with global elevation, I have always exported from project base point and checked the box "include IFCSITE elevation in the site local placement origin".

But now that does not work with me or my colleagues anymore. in any of the revit versions 2019 to 2023.

A workaround is to create a new site without global coordinates and export using "shared coordinates", but that shouldnt be necessary.

I have the same issue.

I have the same issue too - Revit 2023.1- Export IFC v 23.2.3.0.

same problem with 2025. Exporting with shared coordinates and IFCSITE elevation checked elevation -20 cm. And I dont know why

Not sure if this helps?

Wrong Z coordinate exporting model to IFC with Shared Coordinates from Revit

Thanks, but that's not helping. 

Somehow, with the same settings, it once exported to the correct Z-coordinate, but unfortunately, it no longer aligns there.

What a classic statement! 😄
