Working in ac22 and have a file with a site (parent file) and 3 building files (children) hotlinked into it. One of the buildings (child) has a standing seam roof created using the roof surfacer tool. However it doesn't show the standing seam roof surface when you hotlink it into the site file (parent ). The roof structure and the roof surface are on the same layer In the building file (Child) but only the roof structure shows up in the site (parent file). Any ideas or work around out their.
