I need to subtract the voids surfaces/volumes from the entities calculation. How should I proceed?
Answer While compiling the Bill of Quantity of the IFC models (walls, partition walls exc. etc.) specific variables can be used, if present, to consider the net surface and net volume. With these functions is NOT necessary subtract the voids. If, instead, the needs is to fully calculate the entities (walls, partition walls exc. etc.) and then subtract the voids, in this case it became necessary to calculate the entire entity including the voids and in a second row inserting a new measurement referred to the void detraction.
