Which tool is used for accurately drafting and marking circles within a range of diameters, with 1/16 inch increments?

• A. French Curves
• B. Chalk Line
• C. Circle Stencil
• D. Measuring Tape

Answer: (C)

A circle stencil is the best choice because it provides a set of fixed circle sizes that you can select and trace, often in precise increments like 1/16 inch. This lets you draft and mark circles with exact diameters quickly and consistently across a surface. The stencil’s edges give a clean, accurate circumference for each chosen size, which is essential when you need multiple circles at specific, repeatable dimensions. Other tools aren’t suited for this purpose: French curves are for irregular or freehand curves, not true circles with defined diameters; a chalk line marks straight lines; a measuring tape measures length rather than producing circular outlines. If you need any circle sizes within a range in fine steps, the circle stencil fits best.
