Delete Boolean Operation

If a Boolean is at the top level of the tree, then, upon its deletion, the operand bodies of this Boolean operation will be left in the model. However, if a Boolean operation already has dependents, then the Delete Elements dialog box will be launched upon its deletion.

If you select the option Exclude selected elements from model tree in this dialog box, then another dialog will be launched, Select Operation to Reassign Child Operation, that offers selecting one of the Boolean's operands on which all dependents of the Boolean would be transferred.
