If Strictly following the spec, this should be only defined for TIfcRoot, because only IfcRoot has GlobalId. In reality, we need GlobalId at TIfcPersistent to load some files, and we sometimes need | |

Name for the IFC standard, used in IFC files. By default, this is just ClassName with prefix 'T' removed. | |

Globally unique identifier for the object instance. Note: Not declared as TGUID, because TGUID cannot be published, but also we don't really need it: for our purposes, this identifier is just an arbitrary string. Note: IFC 4.3 specification puts this only at IfcRoot, not at every IFC class. But testcase https://github.com/buildingsmart-community/Community-Sample-Test-Files/blob/main/IFC%204.0.2.1%20(IFC%204)/ISO%20Spec%20archive/wall-with-opening-and-window.json (from IFC 4.0) shows this can be present at any IFC class, in particular TIfcGeometricRepresentationContext. In fact, TIfcGeometricRepresentationContext needs to have IFC JSON documentation says this, which seems to (unfortunately it is not unambiguous enough...) allow this at any IFC class: "Whereas the | |

|
Use of the IfcMaterialDefinition subtypes within the material association of an element occurrence or element type. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5456). | |
| Published | property HasExternalReferences: TIfcExternalReferenceRelationshipList read FHasExternalReferences; |
|
Reference to external references, e.g. library, classification, or document information, that are associated to the material. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5460). | |
| Published | property HasProperties: TIfcMaterialPropertiesList read FHasProperties; |
|
Material properties assigned to instances of subtypes of IfcMaterialDefinition. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5463). | |
| Published | property Name: TIfcLabel read FName write FName; |
|
The name by which the material profile is known. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5483). | |
| Published | property Description: TIfcText read FDescription write FDescription; |
|
Definition of the material profile in descriptive terms. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5486). | |
| Published | property Material: TIfcMaterial read FMaterial write FMaterial; |
|
Optional reference to the material from which the profile is constructed. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5489). | |
| Published | property Profile: TIfcProfileDef read FProfile write FProfile; |
|
Identification of the profile for which this material profile is associating material. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5492). | |
| Published | property Priority: Integer read FPriority write FPriority; |
|
The relative priority of the profile, expressed as normalised integer range [0..100]. Controls how profiles intersect in connections and corners of building elements: A profile from one element protrudes into (i.e. displaces) a profile from another element in a joint of these elements if the former element's profile has higher priority than the latter. The priority value for a material profile in an element has to be set and maintained by software applications in relation to the material profiles in connected elements.

| Published | property Category: TIfcLabel read FCategory write FCategory; |
|
Category of the material profile, e.g. the role it has in the profile set it belongs to. The list of keywords might be extended by model view definitions, however the following keywords shall apply in general: * 'LoadBearing' — the material profile having a load bearing function. * 'Insulation' — the material profile having an insolating function. * 'Finish' — the material profile being the finish. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5498). | |
| Published | property ToMaterialProfileSet: TIfcMaterialProfileSet read FToMaterialProfileSet write FToMaterialProfileSet; |
|
Material profile set in which this material profile is included. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 5502). | |
