🔍 Key Concepts

• Standard drafting line types used on blueprints (visible, hidden, center, and dimension lines) • How hidden edges of an object are shown when they are not directly visible • Differences in line weight (thick, medium, thin) and pattern (solid vs dashed)

💭 Think About

• Look at which line style is used to show something that is there but not visible from the viewing angle. • Compare which line type is used for dimensions and measurements versus those used to outline the visible shape of the object. • Ask yourself which of these lines you would expect to see running along the edge of a hole or feature that is behind another surface.

✅ Before You Answer

• Identify which option is a dashed line rather than a continuous solid line. • Among the dashed lines, check which one is shown with medium thickness, not very thin and not very thick. • Be sure you do NOT choose the line type that has arrows or numbers, since that is used for dimensions, not hidden features.
