# STEPControl_Writer Class Reference

This class creates and writes
STEP files from Open CASCADE models. A STEP file can be
written to an existing STEP file or to a new one.
Translation can be performed in one or several operations. Each
translation operation outputs a distinct root entity in the STEP file.

void * | operator new (size_t size)
void | operator delete (void *anAddress)
Standard_EXPORT | STEPControl_Writer ()
| Creates a Writer from scratch .
Standard_EXPORT | STEPControl_Writer (const Handle(XSControl_WorkSession)&WS, const Standard_Boolean scratch=Standard_True)
| Creates a Writer from an already existing Session If <scratch> is True (D), clears already recorded data .
Standard_EXPORT void | SetTolerance (const Standard_Real Tol)
| Sets a length-measure value that will be written to uncertainty-measure-with-unit when the next shape is translated. .
Standard_EXPORT void | UnsetTolerance ()
| Unsets the tolerance formerly forced by SetTolerance .
Standard_EXPORT void | SetWS (const Handle(XSControl_WorkSession)&WS, const Standard_Boolean scratch=Standard_True)
| Sets a specific session to <me> .
Standard_EXPORT Handle_XSControl_WorkSession | WS () const
| Returns the session used in <me> .
Standard_EXPORT Handle_StepData_StepModel | Model (const Standard_Boolean newone=Standard_False)
| Returns the produced model. Produces a new one if not yet done or if <newone> is True This method allows for instance to edit product or header data before writing. .
Standard_EXPORT IFSelect_ReturnStatus | Transfer (const TopoDS_Shape &sh, const STEPControl_StepModelType mode, const Standard_Boolean compgraph=Standard_True)

Translates shape sh to a STEP
entity. mode defines the STEP entity type to be output:
- STEPControlStd_AsIs translates a shape to its highest possible
STEP representation.
- STEPControlStd_ManifoldSolidBrep translates a shape to a STEP
manifold_solid_brep or brep_with_voids entity.
- STEPControlStd_FacetedBrep translates a shape into a STEP
faceted_brep entity.
- STEPControlStd_ShellBasedSurfaceModel translates a shape into a STEP
shell_based_surface_model entity.
- STEPControlStd_GeometricCurveSet translates a shape into a STEP
geometric_curve_set entity.
.

Standard_EXPORT IFSelect_ReturnStatus | Write (const Standard_CString filename)
| Writes a STEP model in the file identified by filename. .
Standard_EXPORT void | PrintStatsTransfer (const Standard_Integer what, const Standard_Integer mode=0) const

Displays the statistics for the
last translation. what defines the kind of statistics that are displayed:
- 0 gives general statistics (number of translated roots,
number of warnings, number of fail messages),
- 1 gives root results,
- 2 gives statistics for all checked entities,
- 3 gives the list of translated entities,
- 4 gives warning and fail messages,
- 5 gives fail messages only.
mode is used according to the use of what. If what is 0, mode is
ignored. If what is 1, 2 or 3, mode defines the following:
- 0 lists the numbers of STEP entities in a STEP model,
- 1 gives the number, identifier, type and result type for each
STEP entity and/or its status (fail, warning, etc.),
- 2 gives maximum information for each STEP entity (i.e. checks),
- 3 gives the number of entities by the type of a STEP entity,
- 4 gives the number of of STEP entities per result type and/or status,
- 5 gives the number of pairs (STEP or result type and status),
- 6 gives the number of pairs (STEP or result type and status)
AND the list of entity numbers in the STEP model.
