BRepAlgoAPI_Splitter Class Reference

The class contains API level of the Splitter algorithm, which allows splitting a group of arbitrary shapes by the other group of arbitrary shapes.
The arguments of the operation are divided on two groups:
Objects - shapes that will be split;
Tools - shapes by which the Objects will be split.
The result of the operation contains only the split parts of the shapes from the group of Objects.
The split parts of the shapes from the group of Tools are excluded from the result.
The shapes can be split by the other shapes from the same group (in case these shapes are interfering). More...

Detailed Description

The class contains API level of the Splitter algorithm, which allows splitting a group of arbitrary shapes by the other group of arbitrary shapes.
The arguments of the operation are divided on two groups:
Objects - shapes that will be split;
Tools - shapes by which the Objects will be split.
The result of the operation contains only the split parts of the shapes from the group of Objects.
The split parts of the shapes from the group of Tools are excluded from the result.
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.
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:
