Detailed Description

The class represents the Building part of the Boolean Operations algorithm.
The arguments of the algorithms are divided in two groups - Objects and Tools.
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.

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.

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.

Additionally to the Warnings of the parent class the algorithm returns the following warnings:

BOPAlgo_AlertEmptyShape - in case some of the input shapes are empty shapes.

Additionally to Errors of the parent class the algorithm returns the following Error statuses:

BOPAlgo_AlertBOPIsNotSet - in case the type of Boolean operation is not set;
BOPAlgo_AlertBOPNotAllowed - in case the operation of given type is not allowed on given inputs;
BOPAlgo_AlertSolidBuilderFailed - in case the BuilderSolid algorithm failed to produce the Fused solid.
