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 | |
| Protected | class function IfcClassName: String; virtual; |
|
Name for the IFC standard, used in IFC files. By default, this is just ClassName with prefix 'T' removed. | |

Properties

|
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 | |

2D transformation that is applied to the texture coordinates. It affects the way texture coordinates are applied to the surfaces of geometric representation items. The 2D transformation supports changes to the size, orientation, and position of textures on shapes. Mirroring is not allowed to be used in the IfcCartesianTransformationOperator.

Texture coordinates, either provided by a corresponding list of texture vertices to vertex-based geometric items or by a texture coordinate generator, that applies the surface texture to the surfaces of the geometric items. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 673). | |
