IFC (IFC4X3_ADD2) under development Pset_PipeSegmentTypeGutter Semantic definition

Gutter segment type common attributes. Applicable entities Properties

Name Property Type Data Type Description
Slope IfcPropertySingleValue IfcPlaneAngleMeasure

Slope angle - relative to horizontal (0.0 degrees).

The shape information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the shape properties, provided in the attached property, the geometric parameters take precedence. For geometry editing applications, like CAD: this value should be write-only.

Angle of the gutter to allow for drainage.

FlowRating IfcPropertySingleValue IfcVolumetricFlowRateMeasure

Actual flow capacity for the gutter. Value of 0.00 means this value has not been set.

Complementaryfunction IfcPropertyEnumeratedValue PEnum_ComplementaryWorks

Indicates the complementary function of the drain channel.

OrthometricHeight IfcPropertySingleValue IfcLengthMeasure

The orthometric height is the vertical distance H along the plumb line from a point of interest to a reference surface known as the geoid, the vertical datum that approximates mean sea level.

IsCovered IfcPropertySingleValue IfcBoolean

This property defines if the drain channel has a cover (TRUE) or not (FALSE).

IsMonitored IfcPropertySingleValue IfcBoolean

This property defines if the Drain Channel is monitored (TRUE) or not (FALSE).
