Set units and Coordinate System into the IFC settings.Even selecting a coordinate system in the IFC writer,the location is lost as you open it into another 3D tool/viewer

Any progress here?I have the same issue,Solibri will not recognize that my IFC-file is in metre,it assumes millimetre...

It seems there are 9 rows related to units - or IFCSIUNIT.
FME only writes one of these:#24=IFCSIUNIT(*,.PLANEANGLEUNIT.,$,.RADIAN.);
Any hope for a fix?The issue is that some software (for instance Solibri) assumes mm,while other software (FME,DDS-CAD Viewer,BIM Vision,ARCHICAD) seems to be able to "guess" the correct unit.
