import IFC, cant see levels

[Foti]

Hello

I am importing a revit IFC file. It works well, it opens and I see the ground floor, all is great but as soon as you select another level, nothing shows up, and when you go back to the ground floor, its all gone.

I re opened it, I see the ground floor, I go straight to the 3D its all there, i can live section it and see everything, once you click a floor level, it disappears.

Any suggestions?

Hello

Never mind my last post, first time working with someone else on revit and ifc exchange , didn't think to look at the layers, all turned off, what a rookie mistake.

Thanks anyways
