Which line is lightly drawn to guide drawing other lines and shapes?

• A. Construction Line
• B. Extension Line
• C. Leader Line
• D. Cabinet Pictorial

Answer: (A)

In technical drawing, the light, faint lines used as guides to lay out the basic geometry are construction lines. They provide a temporary framework for placing shapes, ensuring correct proportions, alignments, and relationships before final lines are drawn. Because they’re meant to be erased, they won’t overpower the finished drawing. Extension lines are used to show where a dimension applies, not to guide the overall shape. Leader lines connect notes to features. Cabinet pictorial is a style of drawing, not a type of line used for guiding construction.
