MassPerLength

P_SINGLEVALUE / IfcMassPerLengthMeasure

| Mass Per Length | Mass 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 Area | Area of the profile. For example measured in mm2. If given, the value of the cross section area shall be greater than zero.

Perimeter

P_SINGLEVALUE / IfcPositiveLengthMeasure

| Perimeter | Perimeter of the profile for calculating the surface area. For example measured in mm.

MinimumPlateThickness

P_SINGLEVALUE / IfcPositiveLengthMeasure

MaximumPlateThickness

P_SINGLEVALUE / IfcPositiveLengthMeasure

| Maximum Plate Thickness | This 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.
