Methods

This item is declared in ancestor TIfcPersistent.
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 | |

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

This item is declared in ancestor TIfcPersistent. 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 | |
