The AreaBreak item type is a classification that identifies the model properties associated with a break shape on a drawing. Its purpose is to group objects graphically to create a select set of the contents. Labels and data can be established on an area break. There is no automatic update between the labels associated with the area break and the objects within the area break. No inconsistencies are generated at the area break if the property values of the area break differ from those of the items inside. This item type is derived from the PlantItemGroup class.
