IfcStructuralSurfaceAction (2)
11 ProjectedOrTrue OPTIONAL IfcProjectedOrTrueLengthEnum

Defines whether load values are given per true lengths of the surface on which they act, or per lengths of the projection of the surface in load direction. The latter is only applicable to loads which act in global coordinate directions.

12 PredefinedType IfcStructuralSurfaceActivityTypeEnum

Type of action according to its distribution of load values.

7.10.3.18.4 Formal propositions

Name Description
ConstPredefinedType

This surface action subtype is restricted to constant load distribution over its domain.

SELF\IfcStructuralSurfaceAction.PredefinedType = IfcStructuralSurfaceActivityTypeEnum.CONST
SuitableLoadType

A planar action shall place either a planar force or a temperature load.
