class ActorWrite from STEPControl
    inherits ActorOfFinderProcess  from Transfer
    
    ---Purpose : This class performs the transfer of a Shape from TopoDS
    --           to AP203 or AP214 (CD2 or DIS)


uses FinderProcess, TransientProcess, Binder, Finder, StepModel from StepData,
     Shape from TopoDS,
     StepModelType from STEPControl,
     Axis2Placement3d from StepGeom,
     ShapeRepresentation from StepShape,
     ShapeDefinitionRepresentation from StepShape,
     HAsciiString from TCollection,
     ContextTool from STEPConstruct,
     Part from STEPConstruct,
     HSequenceOfShape from TopTools, -- For non-manifold topology processing (ssv; 13.11.2010)
     NonManifoldSurfaceShapeRepresentation from StepShape -- For non-manifold topology processing (ssv; 13.11.2010)

	--          Default implementation uses flag GroupMode and analyses
	--          the shape itself
