enum BOPAlgo_GlueEnum 
The Enumeration describes an additional option for the algorithms in the Boolean Component such as General Fuse, Boolean operations, Section, Maker Volume, Splitter and Cells Builder algorithms.
The Gluing options have been designed to speed up the computation of the interference among arguments of the operations on special cases, in which the arguments may be overlapping but do not have real intersections between their subshapes.
This option cannot be used on the shapes having real intersections, like intersection vertex between edges, or intersection vertex between edge and a face or intersection line between faces.
There are two possibilities of overlapping shapes:
Even though there are no real intersections on such cases without Gluing options the algorithm will still intersect the subshapes of the arguments with interfering bounding boxes.
The performance improvement in gluing mode is achieved by excluding the most time consuming computations according to the given Gluing parameter:
By setting the Gluing option for the operation user should guarantee that the arguments are really coinciding. The algorithms do not check this itself. Setting inappropriate option for the operation is likely to lead to incorrect result.
There are following items in the enumeration:
BOPAlgo_GlueOff  default value for the algorithms, Gluing is switched off;
BOPAlgo_GlueShift  Glue option for shapes with partial coincidence;
BOPAlgo_GlueFull  Glue option for shapes with full coincidence.
