Description
Methods
| Protected | function WantsGlobalId: Boolean; virtual; |
|
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 | |

This item is declared in ancestor TIfcTessellatedItem. Assignment of the representation item to a single or multiple layer(s). Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 541). | |
| Published | property StyledByItem: TIfcStyledItem read FStyledByItem write FStyledByItem; |
|
This item is declared in ancestor TIfcTessellatedItem. Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 547). | |
| Published | property CoordIndex: TIntegerList read FCoordIndex; |
|
This item is declared in ancestor TIfcIndexedPolygonalFace. One-dimensional list with the indices for the three or more points, that define the vertices of the outer loop. If the tessellated face set is closed, indicated by TIfcPolygonalFaceSet.Closed, then the points, defining the outer loop, shall connect counter clockwise, as seen from the outside of the body, so that the resulting normal will point outwards.

|
This item is declared in ancestor TIfcIndexedPolygonalFace. Reference to the IfcPolygonalFaceSet for which this face is associated. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 814). | |
| Published | property HasTexCoords: TIfcTextureCoordinateIndices read FHasTexCoords write FHasTexCoords; |
|
This item is declared in ancestor TIfcIndexedPolygonalFace. Optional reference to the IfcTextureCoordinateIndices that provide the texture coordinates for applying textures to this face. Source: scene/load/ifc/castleifc_ifc_standard_types.inc (line 818). | |
