What is a border line on a drawing used for?

• A. Located near the edge of the sheet of drawing paper, used to separate various portions of the drawing.
• B. Indicates the scale of the drawing.
• C. Marks the centerline of walls.
• D. Identifies the sheet name.

Answer: (A)

A border line defines the drawing’s usable area and frames the content near the sheet edge. It creates a clean boundary that separates the drawing itself from the surrounding margins and title-block area, helping ensure nothing important is cut off during printing or trimming and keeping the sheet consistent and readable. This boundary is not where scale, centerlines, or sheet names are shown—scale is indicated by a scale marker, centerlines appear on the drawing itself to show symmetry or alignment, and the sheet name sits in the title block.
