# STEPConstruct_ValidationProps Class Reference

This class provides tools for access (write and read)
the validation properties on shapes in the STEP file.
These are surface area, solid volume and centroid.
.

void * | operator new (size_t, void *anAddress)
void * | operator new (size_t size)
void | operator delete (void *anAddress)
Standard_EXPORT | STEPConstruct_ValidationProps ()
| Creates an empty tool .
Standard_EXPORT | STEPConstruct_ValidationProps (const Handle(XSControl_WorkSession)&WS)
| Creates a tool and loads it with worksession .
Standard_EXPORT Standard_Boolean | Init (const Handle(XSControl_WorkSession)&WS)
| Load worksession; returns True if succeeded .
Standard_EXPORT Standard_Boolean | AddProp (const TopoDS_Shape &Shape, const Handle(StepRepr_RepresentationItem)&Prop, const Standard_CString Descr, const Standard_Boolean instance=Standard_False)
| General method for adding (writing) a validation property for shape which should be already mapped on writing itself. It uses FindTarget() to find target STEP entity resulting from given shape, and associated context Returns True if success, False in case of fail .
Standard_EXPORT Standard_Boolean | AddProp (const StepRepr_CharacterizedDefinition &target, const Handle(StepRepr_RepresentationContext)&Context, const Handle(StepRepr_RepresentationItem)&Prop, const Standard_CString Descr)
| General method for adding (writing) a validation property for shape which should be already mapped on writing itself. It takes target and Context entities which correspond to shape Returns True if success, False in case of fail .
Standard_EXPORT Standard_Boolean | AddArea (const TopoDS_Shape &Shape, const Standard_Real Area)
| Adds surface area property for given shape (already mapped). Returns True if success, False in case of fail .
Standard_EXPORT Standard_Boolean | AddVolume (const TopoDS_Shape &Shape, const Standard_Real Vol)
| Adds volume property for given shape (already mapped). Returns True if success, False in case of fail .
Standard_EXPORT Standard_Boolean | AddCentroid (const TopoDS_Shape &Shape, const gp_Pnt &Pnt, const Standard_Boolean instance=Standard_False)
| Adds centroid property for given shape (already mapped). Returns True if success, False in case of fail If instance is True, then centroid is assigned to an instance of component in assembly .
Standard_EXPORT Standard_Boolean | FindTarget (const TopoDS_Shape &S, StepRepr_CharacterizedDefinition &target, Handle(StepRepr_RepresentationContext)&Context, const Standard_Boolean instance=Standard_False)
| Finds target STEP entity to which validation props should be assigned, and corresponding context, starting from shape Returns True if success, False in case of fail .
Standard_EXPORT Standard_Boolean | LoadProps (TColStd_SequenceOfTransient &seq) const
| Searches for entities of the type PropertyDefinitionRepresentation in the model and fills the sequence by them .
Standard_EXPORT Handle_StepRepr_NextAssemblyUsageOccurrence | GetPropNAUO (const Handle(StepRepr_PropertyDefinition)&PD) const
| Returns CDSR associated with given PpD or NULL if not found (when, try GetPropSDR) .
Standard_EXPORT Handle_StepBasic_ProductDefinition | GetPropPD (const Handle(StepRepr_PropertyDefinition)&PD) const
| Returns SDR associated with given PpD or NULL if not found (when, try GetPropCDSR) .
Standard_EXPORT TopoDS_Shape | GetPropShape (const Handle(StepBasic_ProductDefinition)&ProdDef) const
| Returns Shape associated with given SDR or Null Shape if not found .
Standard_EXPORT TopoDS_Shape | GetPropShape (const Handle(StepRepr_PropertyDefinition)&PD) const
| Returns Shape associated with given PpD or Null Shape if not found .
Standard_EXPORT Standard_Boolean | GetPropReal (const Handle(StepRepr_RepresentationItem)&item, Standard_Real &Val, Standard_Boolean &isArea) const
| Returns value of Real-Valued property (Area or Volume) If Property is neither Area nor Volume, returns False Else returns True and isArea indicates whether property is area or volume .
Standard_EXPORT Standard_Boolean | GetPropPnt (const Handle(StepRepr_RepresentationItem)&item, const Handle(StepRepr_RepresentationContext)&Context, gp_Pnt &Pnt) const
| Returns value of Centriod property (or False if it is not) .
Standard_EXPORT void | SetAssemblyShape (const TopoDS_Shape &shape)
| Sets current assembly shape SDR (for FindCDSR calls) .
