🔍 Key Concepts

• On standard engineering or ship construction drawings, a centerline is usually drawn as a thin line made up of alternating long and short dashes. • A hidden detail or invisible edge is usually shown with evenly spaced dashes of medium thickness, not the same pattern as a centerline. • A dimension line typically has arrowheads and a numerical value between them, which is different from a pure centerline symbol.

💭 Think About

• Look at which of the labeled lines is made of an alternating long‑dash/short‑dash pattern rather than all solid or all evenly dashed. • Ask yourself which line type would logically be used to show the center of symmetry of a hull, shaft, or cylinder on a plan view. • Which choices can you eliminate right away because they are either completely solid, include arrowheads and measurements, or use dashes that are all the same length?

✅ Before You Answer

• Verify that the correct choice is a thin line, not thick or medium, since centerlines are normally drawn light and fine. • Confirm that the dash pattern is long dash – short dash – long dash repeating, not just evenly spaced dashes. • Make sure the option you select does not have arrowheads, numbers, or other dimensioning symbols attached.
