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.
7.10.2.10.2 Type values
| 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.  |
