🔍 Key Concepts

• In mechanical and shipboard drafting, a dimension line is the line that actually carries the numerical measurement on the drawing • Look for arrowheads or terminators that show where the measurement starts and ends • Distinguish between object lines, hidden/center lines, and dimension/extension lines by their thickness and style

💭 Think About

• Which figure shows a line that clearly indicates a measured distance between two points, with a number that represents that distance? • Which line type would you expect to see next to extension lines and numbers when giving the size of a part or space on a blueprint? • Compare the thickness and presence of arrows or symbols at the ends of each line; which format is normally used to show measurements?

✅ Before You Answer

• Verify which figure has arrows or similar marks at both ends with a numeric value placed near or on the line • Confirm that the candidate line is thin, not the thick object or cutting lines • Make sure you are not choosing a hidden, center, or break line style (dashed or wavy) but a continuous measurement line
