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:

The rules for the arguments and type of the operation are the following:

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:

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