تعريف ومعنى "French curve"

What is a "French curve"?

A French curve is a curved template used in drafting and design to draw smooth, irregular curves. It is typically made of plastic or wood and features a series of different curved edges that can be used to create various shapes. The user places the French curve on the paper and traces along its edges to form curves that are difficult to draw freehand. French curves are commonly used by architects, engineers, and designers for precise and consistent curved lines, especially when drawing freeform shapes or when working on detailed technical drawings.
