NameTypeDescription
MassPerLength P_SINGLEVALUE / IfcMassPerLengthMeasure
Mass Per LengthMass per length, i.e. mass of a beam with a unit length of extrusion. For example measured in kg/m.
CrossSectionArea P_SINGLEVALUE / IfcAreaMeasure
Cross Section AreaTotal area of the cross section (or profile) of the object.
Perimeter P_SINGLEVALUE / IfcPositiveLengthMeasure
PerimeterPerimeter of the object. Perimeter of the profile for calculating the surface area. For example measured in mm.
MinimumPlateThickness P_SINGLEVALUE / IfcPositiveLengthMeasure

MaximumPlateThickness P_SINGLEVALUE / IfcPositiveLengthMeasure
Maximum Plate ThicknessThis value may be needed for stress analysis and to handle buckling problems. It can also be derived from the given profile geometry or classification and therefore it is only an optional feature allowing for an explicit description. For example measured in mm.
