01
Identify the object and the orientation of the view
Give the box a reference identifier and attach a sketch or photograph showing which face is considered the front. Mark width, height and depth on that same view. Record the unit beside the values, and state whether the record describes an actual object or a proposed design. If a measurement is approximate, preserve that qualification. A reader should not have to infer the orientation from an isolated list of three numbers or assume that a proposed dimension was measured from the finished object.
02
Separate the object from the space around it
Specify the endpoints used for each dimension, including whether a projecting handle or base is included. Keep object dimensions separate from any proposed surrounding space. In the display example, the team may want room for viewing or access, but that planning allowance is a different entry from the box width. Identify who needs to confirm the allowance for the actual setting. Combining the two into one unexplained number makes it difficult for another person to reconstruct what was measured and what was merely proposed.
03
Keep the source and revision attached to the values
Record when and how the dimensions were obtained, who supplied them and which drawing or object version they describe. If a discrepancy appears, retain both readings with their context until the responsible person resolves it. Update the sketch and value list together so they cannot silently disagree. Before using the record for the next stage, confirm that it still refers to the current object. This traceable set of notes is more useful than a tidy number stripped of the information needed to interpret it.
