IfcProjectLibrary: public Ifc4x2::IfcContext¶
IfcProjectLibrary collects all library elements that are included within a referenced project data set.
Examples for project libraries include:
HISTORY New entity in IFC2x4.
Attribute use definition
SELF\IfcContext.RepresentationContext Context of the representations used within the project library. When the project library includes shape representations for its library type objects, one or several geometric representation contexts need to be included that define the coordinate system, the coordinate space dimensions, and/or the precision factor.
SELF\IfcContext.UnitsInContext Units locally assigned to measure types used within the context of this project library.
NOTE It is generally discouraged to use a different length measure and plane angle measure in an included project library compared with the project itself. It may lead to unexpected results for the shape representation of items included in the project library.
Relationship use definition
Instances of IfcProjectLibrary are assigned to the project context using the IfcRelDeclares relationship and accessible through the inverse attribute HasContext. Individual object types and property (set) templates are assigned to the IfcProjectLibrary using the IfcRelDeclares relationship and are accessible through the inverse attribute Declares.
