Detailed Description

An IfcColumn is a vertical structural member which often is aligned with a structural grid intersection. 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.

<IMAGE ifccolumnstandardcase_axis-01>

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.

<IMAGE ifccolumnstandardcase_axis-02>

The image below illustrates a 'Clipping' geometric representation with use of IfcBooleanClippingResult between an IfcExtrudedAreaSolid and an IfcHalfSpaceSolid to create a clipped body.

<IMAGE ifccolumn_advanced-2-layout1>

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).

<IMAGE ifccolumn_standard-layout1>

The image below illustrates use of a special profile type (here IfcIShapeProfileDef) for the definition of the IfcExtrudedAreaSolid.

<IMAGE ifccolumn_advanced-1-layout1>

<IMAGE ifccolumn-01>

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.

<IMAGE ifccolumn_cardinalpoint>

The image below illustrates assignment of a composite profile by using IfcCompositeProfileDef for geometric representation and several IfcMaterialProfile entities within the IfcMaterialProfileSet.
