Detailed Description

The root API class for performing Boolean Operations on arbitrary shapes.

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:

BOPAlgo_AlertBOPNotSet - in case the type of Boolean Operation is not set.
