Which line style is typically used to emphasise edges in technical drawings?

• A. Thick lines
• B. Dotted lines
• C. Thin lines
• D. Dashed lines

Answer: (A)

Line weight in technical drawings signals what you can see in the view. To emphasise the outer edges of the object, use thick lines for the visible outline so the silhouette stands out clearly. Thin lines are reserved for details like dimension lines or construction aids, and other line types serve other purposes—hidden features are shown with dashed lines, and centre or axis lines use dotted or chain patterns. Using thick lines for the edges makes the main shape read immediately and unambiguously.
