Properties
|
property HasContext: TIfcRelDeclares read FHasContext write FHasContext; |
|
References to the context providing context information such as project unit or representation context. It should only be asserted for the uppermost non-spatial object. Source: src/scene/load/ifc/castleifc_ifc_standard_types.inc (line 1847). | |

property IsDecomposedBy: TIfcRelAggregatesList read FIsDecomposedBy; |
|
References to the decomposition relationship being an aggregation. Source: src/scene/load/ifc/castleifc_ifc_standard_types.inc (line 1850). | |

property HasAssociations: TIfcRelAssociatesList read FHasAssociations; |
|
Reference to the relationship objects, that associates external references or other resource definitions to the object. Examples are the association to library, documentation or classification. Source: src/scene/load/ifc/castleifc_ifc_standard_types.inc (line 1858). | |
