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 class contains API level of the **Splitter** algorithm,
|
|
//! which allows splitting a group of arbitrary shapes by the
|
|
//! other group of arbitrary shapes.<br>
|
|
//! The arguments of the operation are divided on two groups:<br>
|
|
//! *Objects* - shapes that will be split;<br>
|
|
//! *Tools* - shapes by which the *Objects* will be split.<br>
|
|
//! The result of the operation contains only the split parts
|
|
//! of the shapes from the group of *Objects*.<br>
|
|
//! The split parts of the shapes from the group of *Tools* are excluded
|
|
//! from the result.<br>
|
|
//! The shapes can be split by the other shapes from the same group
|
|
//! (in case these shapes are interfering).
|
|
//!
|
|
//! The class is a General Fuse based algorithm. Thus, all options
|
|
//! of the General Fuse algorithm such as Fuzzy mode, safe processing mode,
|
|
//! parallel processing mode, gluing mode and history support are also
|
|
//! available in this algorithm.<br>
|
|
//! There is no requirement on the existence of the *Tools* shapes.
|
|
//! And if there are no *Tools* shapes, the result of the splitting
|
|
//! operation will be equivalent to the General Fuse result.
|
|
//!
|
|
//! The algorithm returns the following Error statuses:<br>
|
|
//! - 0 - in case of success;<br>
|
|
//! - *BOPAlgo_AlertTooFewArguments* - in case there is no enough arguments for the operation;<br>
|
|
//! - *BOPAlgo_AlertIntersectionFailed* - in case the Intersection of the arguments has failed;<br>
|
|
//! - *BOPAlgo_AlertBuilderFailed* - in case the Building of the result has failed.
