A pick ID style object is used to correlate the class of objects within its scope with an integer. This integer may be included in the specification of a picking operation to restrict that operation to the objects in that class. A pick ID style object must be placed in a group or container to have effect; the scope of a pick ID style object placed in a group (or container) is the class of objects located between that style object and the end of that group (or container).
