Hi guys. New user here. I have a question regarding exporting Revit model to Autodesk Live for presentation. At the moment this is my workflow for presentation but the problem is, I modelled a machine outlines as Revit Family, and create service space in shape of door opening. Material of said service space is Air. The problem is when I use Live and with command tap&go I simply cannot go through that service space (Probably because Revit sees it as Solid). Is there any way to adjust it's properties in Revit so It is possible to go through it in Live.

Thanks
Regards
