Setting/Getting data for the algorithm

Sets the arguments

void SetArguments (const NCollection_List< TopoDS_Shape > &theLS)

Gets the arguments.

const NCollection_List< TopoDS_Shape > & Arguments () const

Gets the arguments.

Setting options

Sets the flag that defines the mode of treatment. In non-destructive mode the argument shapes are not modified. Instead a copy of a sub-shape is created in the result if it is needed to be updated.

void SetNonDestructive (const bool theFlag)

Returns the flag that defines the mode of treatment. In non-destructive mode the argument shapes are not modified. Instead a copy of a sub-shape is created in the result if it is needed to be updated.

bool NonDestructive () const

Returns the flag that defines the mode of treatment. In non-destructive mode the argument shapes are not modified. Instead a copy of a sub-shape is created in the result if it is needed to be updated.

void SetGlue (const BOPAlgo_GlueEnum theGlue)

Sets the glue option for the algorithm, which allows increasing performance of the intersection of the input shapes.

BOPAlgo_GlueEnum Glue () const

Returns the glue option of the algorithm.

void SetCheckInverted (const bool theCheck)

Enables/Disables the check of the input solids for inverted status.

bool CheckInverted () const

Returns the flag defining whether the check for input solids on inverted status should be performed or not.

Performing the operation

Performs the algorithm

void Build (const Message_ProgressRange &theRange=Message_ProgressRange()) override

This is called by Shape(). It does nothing but may be redefined.

Result simplification

Simplification of the result shape is performed by the means of ShapeUpgrade_UnifySameDomain algorithm. The result of the operation will be overwritten with the simplified result.

The simplification is performed without creation of the Internal shapes, i.e. shapes connections will never be broken.

Simplification is performed on the whole result shape. Thus, if the input shapes contained connected tangent edges or faces unmodified during the operation they will also be unified.

After simplification, the History of result simplification is merged into the main history of operation. So, it is taken into account when asking for Modified, Generated and Deleted shapes.

Some options of the main operation are passed into the Unifier:

Fuzzy tolerance of the operation is given to the Unifier as the linear tolerance.
Non destructive mode here controls the safe input mode in Unifier.

Parameters

theUnifyEdges	Controls the edges unification. TRUE by default.
theUnifyFaces	Controls the faces unification. TRUE by default.
theAngularTol	Angular criteria for tangency of edges and faces. Precision::Angular() by default.

void SimplifyResult (const bool theUnifyEdges=true, const bool theUnifyFaces=true, const double theAngularTol=Precision::Angular())

const NCollection_List< TopoDS_Shape > & Modified (const TopoDS_Shape &theS) override

const NCollection_List< TopoDS_Shape > & Generated (const TopoDS_Shape &theS) override

Returns the list of shapes generated from the shape <theS>. In frames of Boolean Operations algorithms only Edges and Faces could have Generated elements, as only they produce new elements during intersection:

bool IsDeleted (const TopoDS_Shape &aS) override

Returns true if any of the input shapes has been modified during operation.

virtual bool HasGenerated () const

Detailed Description

The class contains API level of the General Fuse algorithm.

Additionally to the options defined in the base class, the algorithm has the following options:

Safe processing mode - allows to avoid modification of the input shapes during the operation (by default it is off);
Gluing options - allows to speed up the calculation of the intersections on the special cases, in which some sub-shapes are coinciding.
Disabling the check for inverted solids - Disables/Enables the check of the input solids for inverted status (holes in the space). The default value is TRUE, i.e. the check is performed. Setting this flag to FALSE for inverted solids, most likely will lead to incorrect results.
Disabling history collection - allows disabling the collection of the history of shapes modifications during the operation.

It returns the following Error statuses:

0 - in case of success;
BOPAlgo_AlertTooFewArguments - in case there are no enough arguments to perform the operation;
BOPAlgo_AlertIntersectionFailed - in case the intersection of the arguments has failed;
BOPAlgo_AlertBuilderFailed - in case building of the result shape has failed.

Warnings statuses from underlying DS Filler and Builder algorithms are collected in the report.

The class provides possibility to simplify the resulting shape by unification of the tangential edges and faces. It is performed by the method SimplifyResult. See description of this method for more details.
