You are correct, the problem seems to be in the different viewers and not the Revit export. Solibri = Dispays Longitude, Latitude and Elevation DDS-CAD Viewer = Displays Elevation, Correct location on map RDF IfcViewer = No data KIT IfcStoreyView = Displays Longitude, Latitude Regards, Marcus

Thank you for the response. I have tried this also and I can locate the coordinates in the text file but it does not appear to be in the correct place. 312= IFCSITE('0ipprbKJL4bwjtOdN0D7hm',#41,'Default',$,'',#311,$,$,.ELEMENT.,(42,21,31,181945),(-71,-3,-24,-263305),0.,$,$); Reviewing in DDS-CAD or IfcViewer returns blank as you can see in attached PDF. Where can I find it?

Hi, Is the export of Longitude and Latitude from Revit to IFC supported according to the IFC schema? I have tried adding two parameters to Project Information, RefLatitude and RefLongitude but these do not export. Is there a way to get this information to IFC? EXPRESS specification: ENTITY IfcSite SUBTYPE OF ( IfcSpatialStructureElement); RefLatitude : OPTIONAL IfcCompoundPlaneAngleMeasure; RefLongitude : OPTIONAL IfcCompoundPlaneAngleMeasure; RefElevation : OPTIONAL IfcLengthMeasure; LandTitleNumber...

This is the Revit and IFC-file I have used for testing.
