Agreement on use of ParameterTakesPrecedence
Based on IFC2x3
Initiator Official buildinSMART IFC2x3 CV2.0 certification programme
Effects Coordination View 2.0
Date 2013 09
Within the IFC2x3 Coordination View 2.0 each door and window shall have an explicit shape representation, and one should not rely on the lining and panel parameters, added. Those shall only be used for informational purposes.
Therefore it is agreed:
* for IfcWindow and IfcDoor - the parameter “ParameterTakesPrecedence” is always FALSE and explicit geometry of the IfcWindow and IfcDoor is always provided.
* for backward compatibility, a receiving application can always assume “ParameterTakesPrecedence” is interpreted as FALSE, even if the files indicates a TRUE or NULL value, and lining and panel parameters are attached.
