Hi !

You could try to open your IFC file in the notepad, you will probably find a information like

"#12= IFCSIUNIT(*,.LENGTHUNIT.,$,.FEET.);"

and replace FEET for METER

however, if it is set on meters in your c3D it is wierd that it is happening... check if you update you IFC 4x3 export tool

please let me now if any of these could fix your problem

Hi

I see you where using IFC 2.0 which is not reliable for infraestructure, I think this might be the source of your problem

I should be using an updated version of Civil 3D to export IFC 4x3 using the command "IFCINFRAEXPORT"

Try opening this new IFC file attached in your Navisworks. This might work now
