This is an example of the graphic representation of an equipment piece in an elevation drawing.
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.
Dimensions all columns, pipes, and grid lines. Equipment parts are only dimensioned as anchors, which means they are only dimensioned when they are in close proximity to a group of dimensioned objects. If an equipment part is not close enough to a group of dimensioned objects in a particular quadrant, it is not dimensioned.
