0028747: Incorrect result of the section operation after edge refinement
Implementation of the method for simplification of the result of Boolean Operation on the API level. The method BRepAlgoAPI_BuilderAlgo::SimplifyResult has been added, so the derived classes such as BooleanOpeation and Splitter can also use this method. The result shape simplification should be called after the operation is done. The simplification is performed by the means of ShapeUpgrade_UnifySameDomain algorithm. Draw command "bsimplify" has been added to control the simplification options. Documentation for new functionality and draw commands controlling the options of Boolean operations. Test cases for the new functionality. Side-effect change: The algorithms in Boolean component have been changed to use the BRepTools_History as a History tool. Now it became possible to disable the collection of shapes modifications during Boolean Operations, which may be useful for performance sake (in draw the option is controlled by *setfillhistory* command). Draw command "unifysamedom" has been changed to accept the angular tolerance in degrees instead of radians.

//! The abstract class BooleanOperation is the root
|
||||
//! class of Boolean Operations (see Overview).
|
||||
//! Boolean Operations algorithm is divided onto two parts:<br>
|
||||
//! - The first one is computing interference between arguments;<br>
|
||||
//! - The second one is building the result of operation;<br>
|
||||
//! The class BooleanOperation provides API level of both parts.<br>
|
||||
//! The root API class for performing Boolean Operations on arbitrary shapes.
|
||||
//!
|
||||
//! Additionally to the errors of the parent class the algorithm
|
||||
//! returns the following Error statuses:<br>
|
||||
//! - 0 - in case of success;<br>
|
||||
//! The arguments of the operation are divided in two groups - *Objects* and *Tools*.
|
||||
//! Each group can contain any number of shapes, but each shape should be valid
|
||||
//! in terms of *BRepCheck_Analyzer* and *BOPAlgo_ArgumentAnalyzer*.
|
||||
//! The algorithm builds the splits of the given arguments using the intersection
|
||||
//! results and combines the result of Boolean Operation of given type:
|
||||
//! - *FUSE* - union of two groups of objects;
|
||||
//! - *COMMON* - intersection of two groups of objects;
|
||||
//! - *CUT* - subtraction of one group from the other;
|
||||
//! - *SECTION* - section edges and vertices of all arguments;
|
||||
//!
|
||||
//! The rules for the arguments and type of the operation are the following:
|
||||
//! - For Boolean operation *FUSE* all arguments should have equal dimensions;
|
||||
//! - For Boolean operation *CUT* the minimal dimension of *Tools* should not be
|
||||
//! less than the maximal dimension of *Objects*;
|
||||
//! - For Boolean operation *COMMON* the arguments can have any dimension.
|
||||
//! - For Boolean operation *SECTION* the arguments can be of any type.
|
||||
//!
|
||||
//! Additionally to the errors of the base class the algorithm returns
|
||||
//! the following Errors:<br>
|
||||
//! - *BOPAlgo_AlertBOPNotSet* - in case the type of Boolean Operation is not set.<br>
