7.6.4.22.3 Properties

Name Property Type Data Type Description
NominalBodyLength IfcPropertySingleValue IfcPositiveLengthMeasure

Nominal or quoted length measured along the x-axis of the local coordinate system of the object.

NominalBodyWidth IfcPropertySingleValue IfcPositiveLengthMeasure

Nominal or quoted length, measured along the y-axis of the local coordinate system of the object.

NominalBodyDepth IfcPropertySingleValue IfcPositiveLengthMeasure

Nominal or quoted length measured along the z-axis of the local coordinate system of the object.

GullyType IfcPropertyEnumeratedValue PEnum_GullyType

Identifies the predefined types of gully from which the type required may be set.

HasStrainer IfcPropertySingleValue IfcBoolean

Indicates whether the gully trap has a strainer (= TRUE) or not (= FALSE).

TrapType IfcPropertyEnumeratedValue PEnum_TrapType

Identifies the predefined types of trap from which the type required may be set.

OutletConnectionSize IfcPropertySingleValue IfcPositiveLengthMeasure

Size of the outlet connection from the object.

BackInletPatternType IfcPropertyEnumeratedValue PEnum_BackInletPatternType

Identifies the pattern of inlet connections to a gully trap.

A gulley trap may have 0,1,2,3 or 4 inlet connections and the pattern of their arrangement may vary. The enumeration makes the convention that an outlet is either vertical or is placed at the bottom (south side) of the gully trap (when viewed in plan). Position 1 is to the left (west), position 2 is to the top (north), position 3 is to the right (east) and position 4 is to the bottom (south).

InletConnectionSize IfcPropertySingleValue IfcPositiveLengthMeasure

Size of the inlet connection. Note that all inlet connections are assumed to be the same size.

CoverLength IfcPropertySingleValue IfcPositiveLengthMeasure

The length measured along the x-axis in the local coordinate system or the radius (in the case of a circular shape in plan) of the cover of the object.

CoverWidth IfcPropertySingleValue IfcPositiveLengthMeasure

The length measured along the y-axis in the local coordinate system of the cover of the object.
