Graphic Rule
This is an example of the graphic representation of an Equipment component in an isometric drawing.
Label Rule
Every piece of equipment is labeled. The label is placed in the center of the equipment, unless there is an object already in the center or there is insufficient white space for the label. If the label cannot be placed on the center of the object, it is placed with a jogged leader. In the example below, the label is placed inside the object without a leader.
