Public Types

enum Value

Definition from IAI: Enumeration defining the distribution of load values in a curve action or reaction.

HISTORY New type in IFC 2x4


CONST The load has a constant value over its entire extent. LINEAR The load value is linearly distributed over the load’s extent. POLYGONAL The load consists of several consecutive linear sections. EQUIDISTANT The load consists of n consecutive sections of same length and is specified by n+1 load samples. The interpolation type over the segments is not defined by this distribution type but may be qualified in IfcObject.ObjectType based on additional agreements. SINUS The load value is distributed as a sinus half wave. PARABOLA The load value is distributed as a half wave described by a symmetric quadratic parabola. DISCRETE The load is specified as a series of discrete load points. USERDEFINED The load distribution is user-defined. NOTDEFINED The load distribution is undefined.
