I understand that LODs (level of detail / development / design / whatever) are rather loosely defined, but it does serve a useful primary purpose - that at different stages of the design, BIM elements have varying levels of “resolution”. This information is useful, because right now, given a vanilla BIM model in practically any format (not just IFC), it is impossible for anyone to know how accurate that model is and what they can trust. It also doesn’t help that programs like Revit don’t understand the concept of NULL attribute value = don’t export, and tend to put a bunch of properties in there that may or may not be audited. This is bad - because architects don’t know what is resolved and what isn’t, QSes may not know how much error could be in the costing, shop drawers might not know what is ready and what isn’t, etc.
Does IFC have any concept following the premise of an LOD? i.e. that an element can be very resolved, or just schematic?
