Wrong site elevation in IFC export

Chaikampa — Mon, 30 May 2022 11:23:56 GMT

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.

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! 😄
