BIM model layers

As of version 2023.b, Open BIM Quantities offers three different ways of displaying the BIM model component tree in the “Quantities of the BIM model” tab. Up until now, the elements could be arranged according to the IFC entity to which they belong (IfcWall, IfcSlab, IfcSpace, etc.) or the spatial structure (IfcSite->IfcBuilding-> IfcBuildingStorey, etc.). In this update, the “Layers” button has been added to the “View” group of options in the application toolbar. By clicking on it, the tree is organised according to the layers defined in the IFC model. In this case, the layer components are grouped together in a tree branch being assigned the name of that layer.
