IfcDefinedSymbol

Definition from IAI: A defined symbol is a symbolic representation that gets its shape information by an established convention, either through a predefined symbol, or an externally defined symbol.

NOTE: The IfcDefinedSymbol is an entity that had been adopted from ISO 10303, Industrial automation systems and integration—Product data representation and exchange, Part 46: Integrated generic resources: Visual presentation.

NOTE Corresponding STEP name: defined_symbol. The target attribute used the 2d Cartesian transformation operator, including the non-uniform subtype, which is available in IFC (instead of the symbol_target). Please refer to ISO/IS 10303-46:1994 for the final definition of the formal standard.
