: public Ifc2x3::IfcGeometricRepresentationItem¶ Definition from ISO/CD 10303-42:1992: A placement entity defines the local environment for the definition of a geometry item. It locates the item to be defined and, in the case of the axis placement subtypes, gives its orientation.
Additional definition from ISO/WD SC4/WG12/N071 Part42.2 geometry_schema: A placement locates a geometric item with respect to the coordinate system of its geometric context.
IfcPlacement is an abstract supertype not to be directly instantiated, whereas the ISO 10303-42 entity placement can be instantiated to define a placement without orientation. The derived attribute Dim has been added, see also note at IfcGeometricRepresentationItem.
NOTE: Corresponding ISO 10303 entity: placement. Please refer to ISO/IS 10303-42:1994, p. 27 for the final definition of the formal standard.
