Instead of True North, a Project North is used. I have exported IFC model with native Revit IFC export and loading it into Navisworks. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox off - model is loaded to correct Shared coordinate X and Y but Z is 0. Orientation is correct. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox on - model is loaded to correct Shared coordinate X, Y and Z. I'm using Revit 2019 of course as this is about IFC 2019 plugin. The situation with problems is: I think plugin is working correctly to some extent: I have exported IFC model with IFC 2019 plugin - Project Origin set to 'Current shared coordinates' and loading it into Navisworks. - Navisworks Application Menu - Options - IFC - Revit IFC - checkbox off - model is loaded to correct Shared coordinate X and Y but Z is 0. I have a similar issue as Klas described.

Unless the other software has 'Revit IFC' fix implemented. If other software (like BIMsight) is used, using IFC file export from Revit with a plugin or native IFC export, IFC model will be positioned to wrong Z coordinate.

Navisworks implemented a fix for the incorrect position of IFC file export from Revit. Navisworks Application Menu - Options - IFC - Revit IFC - checkbox on - model is loaded to correct Shared coordinate X, Y and Z. I have exported IFC model with native Revit IFC export and loading it into Navisworks. Instead of True North, a Project North is used. Navisworks Application Menu - Options - IFC - Revit IFC - checkbox off - model is loaded to correct Shared coordinate X and Y but Z is 0.
