Robot indicates the overlapping parts of selected objects, which leads to the definition of the common part of the indicated surfaces (objects).
As a result of this operation, Robot generates an object that is a common part of all the selected objects. If the objects do not have a common part, an empty object list is obtained.
The operation is presented diagrammatically in the following image (in the form of an operation on sets).
A complex object indicated by a user-defined number can be created out of any number of selected objects. For double-operand operations, the objects must be divided into two sets (operand A and operand B).
