Chain Dimensioning is commonly known as:

• A. Date Dimensioning
• B. Datum Dimensioning
• C. Point-to-point Dimensioning
• D. Protrusion Dimensioning

Answer: (C)

Chain dimensioning is the method where each measurement is taken from one feature to the next along the part, creating a sequence of distances that add up to the overall length. Because the dimensions are chained from point to point, this approach is commonly called point-to-point dimensioning. For example, you would dimension from the left face to the first shoulder, then from that shoulder to the next feature, and so on, with the total length being the sum of those distances. The other terms don’t fit this concept: date dimensioning isn’t a recognized way to describe how dimensions are laid out; datum dimensioning uses fixed reference datums rather than a chain of measurements between successive features; protrusion dimensioning refers to how far a feature sticks out from a surface rather than a sequential point-to-point measurement system.
