From version 2021.f onwards, "Open BIM Quantities" can incorporate the sets of properties and quantities defined at type level, based on the IFC standard specification. All model components belonging to the same type assume the properties and quantities specified at type level. However, it is possible that element-level definitions may invalidate these type-derived properties and quantities. The different combinations are shown in the list of parameters associated with the model component as follows:
- If the property or quantity is defined at a component level only, the property or quantity’s reference and value are displayed in plain text.
- If the property or quantity is defined at type level, the name of the property or quantity and its value are displayed in italics.
- If the property or quantity is defined at type level, but is different at component level, the name and value at component level are shown in plain text while the type name and value are shown in italics and strikethrough.
