Try zoom all (ZA) in a 3D view and without any filters applied.
unfortunately ive tried that and nothing happens for some reason its just the walls don't appear!
Do you mean that everything of your IFC is visible, but the walls?
yeah everything else is there just the walls not appearing I have tried everything in VG and tried re loading it back in but still nothing shows
Can you upload the model to check it?
sorry for the delay getting back to you, but I have solved it now the IFC file that I had was not complete and had numerous errors in the model thanks for your help though guys!
