class Assembly from STEPConstruct
---Purpose : This operator creates an item of an assembly, from its
-- basic data : a ShapeRepresentation, a Location ...
--
-- Three ways of coding such item from a ShapeRepresentation :
-- - do nothing : i.e. informations for assembly are ignored
-- - create a MappedItem
-- - create a RepresentationRelationship (WithTransformation)
uses
Trsf from gp,
InterfaceModel from Interface,
Axis2Placement3d from StepGeom,
ShapeRepresentation from StepShape,
ShapeDefinitionRepresentation from StepShape,
NextAssemblyUsageOccurrence from StepRepr,
ContextDependentShapeRepresentation from StepShape
is
Create returns Assembly from STEPConstruct;
Init (me: in out; aSR, SDR0: ShapeDefinitionRepresentation from StepShape;
Ax0, Loc : Axis2Placement3d from StepGeom);
---Purpose : Initialises with starting values
-- Ax0 : origin axis (typically, standard XYZ)
-- Loc : location to which place the item
-- MakeMappedItem (me: in out);
---Purpose : Makes a MappedItem
-- Resulting Value is returned by ItemValue
MakeRelationship (me: in out);
---Purpose : Make a (ShapeRepresentationRelationship,...WithTransformation)
-- Resulting Value is returned by ItemValue
ItemValue (me) returns Transient;
---Purpose : Returns the Value
-- If no Make... has been called, returns the starting SR
ItemLocation (me) returns Axis2Placement3d from StepGeom;
---Purpose : Returns the location of the item, computed from starting aLoc
GetNAUO (me) returns NextAssemblyUsageOccurrence from StepRepr;
---Purpose: Returns NAUO object describing the assembly link
CheckSRRReversesNAUO (myclass; Model: InterfaceModel from Interface;
CDSR : ContextDependentShapeRepresentation from StepShape)
returns Boolean;
---Purpose: Checks whether SRR's definition of assembly and component contradicts
-- with NAUO definition or not, according to model schema (AP214 or AP203)
--
