It represents a vertical, or nearly vertical, structural member that transmits, through compression, the weight of the structure above to other structural elements below. It represents such a member from an architectural point of view. It is not required to be load bearing. - Details - There are two main representations for column occurrences: * IfcColumn with IfcMaterialProfileSetUsage is used for all occurrences of columns, that have a profile defined that is swept along a directrix. The profile might change uniformly by a taper definition along the directrix. The profile parameter and its cardinal point of insertion can be fully described by the IfcMaterialProfileSetUsage. These columns are always represented geometrically by an 'Axis' and a 'SweptSolid' or 'AdvancedSweptSolid' shape representation (or by a 'Clipping' geometry based on the swept solid), if a 3D geometric representation is assigned. * IfcColumn is used for all other occurrences of columns, particularly for columns with changing profile sizes along the extrusion, or columns defined by non-linear extrusion, or columns having only 'Brep', or 'SurfaceModel' geometry, if a more parametric representation is not intended. - Axis 3D Geometry - The axis representation can be used to represent the fundamental orientation and extents of a column's body. If an IfcMaterialProfileSetUsage is used, the axis representation is used to locate the profile. In addition: * For a body representation using an IfcExtrudedAreaSolid, the axis can be an IfcPolyline having two Points, or IfcTrimmedCurve with BasisCurve of type IfcLine. The axis curve lies on the z axis of the object coordinate system. * For a body representation using an IfcRevolvedAreaSolid, the axis can be an IfcTrimmedCurve with BasisCurve of type IfcCircle. The axis curve lies on the x/z plane of the object coordinate system, the tangent at the start is along the positive z-axis. As shown on the image below, the axis representation must be positioned at the IfcMaterialProfileSetUsage.CardinalPoint, and parallel to the IfcExtrudedAreaSolid.ExtrudedDirection. This offset between the axis line and the IfcExtrudedAreaSolid.Position must correlate with the chosen IfcMaterialProfileSetUsage.CardinalPoint. - Body AdvancedSweptSolid Geometry - The following additional constraints apply to the 'AdvancedSweptSolid' representation type: * Solid: IfcSurfaceCurveSweptAreaSolid, IfcFixedReferenceSweptAreaSolid, IfcExtrudedAreaSolidTapered, IfcRevolvedAreaSolidTapered is supported * Profile: see 'SweptSolid' geometric representation * Extrusion: not applicable - Body Clipping Geometry - * IfcExtrudedAreaSolid, IfcRevolvedAreaSolid is supported * All subtypes of IfcProfileDef (with exception of IfcArbitraryOpenProfileDef) is supported * All extrusion directions is supported * The IfcBooleanClippingResult is supported, allowing Boolean differences between the swept solid (here IfcExtrudedAreaSolid) and one or several IfcHalfSpaceSolid The image below illustrates a 'Clipping' geometric representation with use of IfcBooleanClippingResult between an IfcExtrudedAreaSolid and an IfcHalfSpaceSolid to create a clipped body. - Body SweptSolid Geometry - * IfcExtrudedAreaSolid, IfcRevolvedAreaSolid is supported * All subtypes of IfcProfileDef (with exception of IfcArbitraryOpenProfileDef) are supported * All extrusion directions are supported The image below illustrates a 'SweptSolid' geometric representation. There are no restrictions or conventions on how to use the object placement (black), extrusion placement (red) and profile placement (green). The image below illustrates use of a special profile type (here IfcIShapeProfileDef) for the definition of the IfcExtrudedAreaSolid. - Material Profile Set Usage - The image below illustrates assignment of IfcMaterialProfileSetUsage and IfcMaterialProfileSet to the IfcColumnType and the IfcColumn occurrence. Both the IfcMaterialProfileSet and IfcProfileDef is shared between all occurrences. The image below illustrates cardinal point alignment. The use of IfcCardinalPointEnum must be consistent with the placement of the extrusion body provided by IfcExtrudedAreaSolid.Position. The image below illustrates assignment of a composite profile by using IfcCompositeProfileDef for geometric representation and several IfcMaterialProfile entities within the IfcMaterialProfileSet. - Material Set - This concept can be applied to the following resources: * LoadBearing - Object Typing - This concept can be applied to the following resources: * IfcColumnType - Product Assignment - This concept can be applied to the following resources: * IfcStructuralCurveMember - An idealized structural member corresponding to the column. * IfcTask - A task for operating on the column. - Property Sets for Objects - This concept can be applied to the following resources: * Pset_ConcreteElementGeneral * Pset_PrecastConcreteElementFabrication * Pset_PrecastConcreteElementGeneral * Pset_ColumnCommon * Pset_ReinforcementBarPitchOfColumn - Quantity Sets - This concept can be applied to the following resources: * Qto_ColumnBaseQuantities - Spatial Containment - The IfcColumn, as any subtype of IfcBuildingElement, can participate alternatively in one of the two different containment relationships: * the Spatial Containment (defined here) * the Element Composition */ class IFC2X_FINAL_EXPORT IfcColumn : public IfcBuildingElement { //DOM-IGNORE-BEGIN OD_EXP_DECLARE_MEMBERS(OdIfc2x_final::IfcColumn); //DOM-IGNORE-END public: /** \details Returns a type of a class instance. \returns Pointer to the OdDAI::Entity type that determines an entity definition within a schema. */ virtual OdDAI::Entity* getInstanceType() const override; /** \details Checks whether the specified instance is the object derived from or belongs to this class. \param entityType [in] Entity to check. \returns true if the specified instance is the object derived from or belongs to this class, false otherwise. */ virtual bool isKindOf(OdIfc::OdIfcEntityType entityType) const override; /** \details Returns the type of this entity. \returns A value of the OdIfc::OdIfcEntityType type that represents type of this entity. */ virtual OdIfc::OdIfcEntityType type() const override; }; /** \details A data type that represents a smart pointer to a IfcColumn object. */ typedef OdSmartPtr IfcColumnPtr; } // namespace #include "TD_PackPop.h" #endif // _IFC2X_FINAL_IFCCOLUMN_AUTO_IMPL_H
