The IfcColumnStandardCase handles all cases of columns, that: * have a reference to the IfcMaterialProfileSetUsage defining the material profile association of the column with the cardinal point of its insertion relative to the local placement. * are based on a sweep of a planar profile, or set of profiles, as defined by the IfcMaterialProfileSet * have an 'Axis' shape representation with constraints provided below in the geometry use definition * have a 'Body' shape representation with constraints provided below in the geometry use definition * have a start profile, or set of profiles, that is swept along the directrix and might be changed uniformly by a taper definition * are consistent in using the correct cardinal point offset of the profile as compared to the 'Axis' and 'Body' shape representation * are extruded perpendicular to the profile definition plane - Material Profile Set Usage - The IfcColumnStandardCase defines in addition that the IfcColumnType should have a unique IfcMaterialProfileSet, that is referenced by the IfcMaterialProfileSetUsage assigned to all occurrences of this IfcColumnType. Composite profile columns can be represented by referring to several IfcMaterialProfile's within the IfcMaterialProfileSet that is referenced from the IfcMaterialProfileSetUsage. The image below illustrates assignment of IfcMaterialProfileSetUsage and IfcMaterialProfileSet to the IfcColumnStandardCase as the column occurrence and to the IfcColumnType. The same IfcMaterialProfileSet is shared by many occurrences of IfcMaterialProfileSetUsage. This relationship is consistent to the relationship between the IfcColumnType and the IfcColumnStandardCase. The image below illustrates cardinal point alignment. The image below illustrates assignment of a composite profile by using IfcCompositeProfile for geometric representation and several IfcMaterialProfile's within the IfcMaterialProfileSet. The number of IfcMaterialProfile's within the IfcMaterialProfileSet is restricted to maximal 2 and requires the use of IfcExtrudedAreaSolidTapered, or IfcRevolvedAreaSolidTapered for the correct 'Body' shape representation. - Product Placement - This concept applies to this entity as specified below: * IfcLocalPlacement (relative) - Relative placement according to position and rotation relative to container. * IfcLocalPlacement (absolute) - Absolute placement according to position and rotation of world coordinate system. * IfcGridPlacement - Placement according to grid intersection. - Axis 3D Geometry - This concept applies to this entity as specified in the table below: IdentifierTypeItemsDescription Axis Curve3D IfcBoundedCurve Three-dimensional reference curve for the column.
The following additional constraints apply to the 'Axis' representation, if the 'Body' shape representation has the RepresentationType : 'SweptSolid': * IfcPolyline having two Points, or IfcTrimmedCurve with BasisCurve of Type IfcLine for 'SweptSolid' provided as IfcExtrudedAreaSolid. The axis curve lies on the z axis of the object coordinate system. * IfcTrimmedCurve with BasisCurve of Type IfcCircle for 'SweptSolid' provided as IfcRevolvedAreaSolid. 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 is defined along the z axis of the object coordinate system. The axis representation can be used to represent the system length of a column that can extent the body length of the column. As shown on the image below, the axis representation is used to represent the cardinal point as the offset between the 'Axis' and the extrusion path of the column. The extrusion path is provided as IfcExtrudedAreaSolid.ExtrudedDirection and should be parallel to the 'Axis'. It has to be guaranteed that the value provided by IfcMaterialProfileSetUsage.CardinalPoint is consistent to the IfcExtrudedAreaSolid.Position. - Body SweptSolid Geometry - The following additional constraints apply to the 'SweptSolid' representation: * Solid: IfcExtrudedAreaSolid, IfcRevolvedAreaSolid are supported * Profile: all subtypes of IfcProfileDef (with exception of IfcArbitraryOpenProfileDef) * Profile Position : For all single profiles, the IfcParameterizedProfileDef.Position is NIL, or having Location = 0.,0. and RefDirection = 1.,0. * Extrusion: perpendicular to the profile direction. The IfcExtrudedAreaSolid.ExtrudedDirection is [0.,0.,1.]. * Orientation: The y-axis of the profile, as determined by IfcSweptAreaSolid.Position.P[2] points to the Y-Axis. It indicates the "role" of the column, a role=0° means y-axis of profile = Y-axis of reference coordinate system. The following interpretation of dimension parameter applies for rectangular columns: * IfcRectangleProfileDef.YDim interpreted as column width * IfcRectangleProfileDef.XDim interpreted as column depth The following interpretation of dimension parameter applies for circular columns: * IfcCircleProfileDef.Radius interpreted as column radius. - Body Clipping Geometry - The following constraints apply to the 'Clipping' representation: * Solid: see 'SweptSolid' geometric representation * Profile: see 'SweptSolid' geometric representation * Profile Position : see 'SweptSolid' geometric representation * Extrusion: see 'SweptSolid' geometric representation * Orientation: see 'SweptSolid' geometric representation * Boolean result: The IfcBooleanClippingResult is supported, allowing Boolean differences between the swept solid (here IfcExtrudedAreaSolid) and one or several IfcHalfSpaceSolid (or its subtypes). The image below illustrates a 'Clipping' geometric representation with use of IfcBooleanClippingResult between an IfcExtrudedAreaSolid and an IfcHalfSpaceSolid to create a clipped body, with cardinal point applied as 2 (bottom center). */ class IFC4X1_EXPORT IfcColumnStandardCase : public IfcColumn { //DOM-IGNORE-BEGIN OD_EXP_DECLARE_MEMBERS(OdIfc4x1::IfcColumnStandardCase); //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 IfcColumnStandardCase object. */ typedef OdSmartPtr IfcColumnStandardCasePtr; } // namespace #include "TD_PackPop.h" #endif // _IFC4X1_IFCCOLUMNSTANDARDCASE_AUTO_IMPL_H
