What is working from a datum?Show answer
A datum is one chosen straight edge that every measurement is taken from. Always measure from the same datum, not from the previous mark, because errors from each mark would otherwise add up. Marking all positions from one datum edge keeps the whole piece accurate and the parts aligned.

A quick check before cutting catches mistakes while material can still be saved.
