How to Set Datums for Panel Inspection
A datum gives production, measurement and installation a shared reference. If a curved part is aligned using only the visible face, a best fit can obscure a misplaced fixing or trim edge.
What to check on your project
Identify the controlling reference points and orientation on the drawing. Have the inspection team report face, edge and fixing positions in the agreed coordinate system. Keep the datum definition consistent across revisions.
