According to the [element decomposition concept](https://ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IFC4x3/HTML/concepts/Object_Composition/Aggregation/Element_Decomposition/content.html) it says: > By default the following constraints apply to an element being decomposed by Element Decomposition: > > Body Geometry — composite is...
Pset_ConstructionOccurence and Pset_InstallationOccurrence both have InstallationDate. Both properties have the same description of "Date on which the element is installed" Both Psets are applicable to IfcElement. Proposal 1: remove from...
IfcLogical as a data type presents a few issues: 1. Complexity of serialisation: many serialisations understand booleans, but few understand logical. This prevents IFC being easier to express (ahahah get...
In IFC2X3, PointOfContact has a type of IfcPropertyReferenceValue pointing to an IfcOrganization. This reference is then used in the COBie 2.4 mappings from IFC to the COBie spreadsheet (such as...
Reading back to the draft AOH-BSEM spec, it seems as though the difference is that Pset_ManufacturerTypeInformation.ModelReference is the manufacturer's "model number / reference" whereas Pset_ConstructionOccurance.ModelNumber is the "occurrence's installed model...
If PEnum_ElementStatus is set to OTHER, there is nowhere for the user to fill out the "userdefined" status. Perhaps this is OK and the intention is to use IfcTasks for...
It's a real pain when filtering: https://github.com/IfcOpenShell/IfcOpenShell/issues/2741 This is similar to how MEP equipment have their size dimensions spread across many psets. There really should be a Pset_Status, also allowing...
The Tag attribute has this description: > The tag (or label) identifier at the particular instance of a product, e.g. the serial number, or the position number. It is the...
I don't see the logic of why building element proxies have a HasObjectName WR. Many objects in our industry use names at a type level, not the occurrence, so there...
