7.10.2.10 IfcStructuralSurfaceActivityTypeEnum

7.10.2.10.1 Semantic definition

This enumeration defines the distribution of load values in a surface action or reaction.

Type	Description
`BILINEAR`	The load value is bilinearly distributed over the load's extent.
`CONST`	The load has a constant value over its entire extent.
`DISCRETE`	The load is specified as a series of discrete load points.
`ISOCONTOUR`	The load is specified by a series of iso-curves (level sets), i.e. curves at which the load value is constant. These curves run perpendicularly to the load gradient.
`USERDEFINED`	The load distribution is user-defined.
`NOTDEFINED`	The load distribution is undefined.
