French curve

n. A flat drafting instrument with curved edges and several scroll-shaped cutouts, used as a guide in drawing curves when constructing graphs or making engineering drawings.

French curve

n (Tools) a thin plastic sheet with profiles of several curves, used by draughtsmen for drawing curves

French′

(or french′) curve′,

n. a flat drafting instrument, the edges of which are cut into several scroll-like curves enabling lines of varying curvature to be drawn. [1880–85]

French Curve

french curve

[¦french ′kərv] (graphic arts) A guide, usually made of clear plastic, used for making regular, irregular, and reverse curves in mechanical drawings and illustrations.

French Curve

(also template; see [2] below). (1) A drawing instrument for drawing or checking curved lines in drafting or design work; they may have fixed or variable curvature. French curves with fixed curvature are wooden, plastic, or less frequently metal plates with a curved edge. A curve with variable curvature is usually a steel guide bar with an arrangement for varying its configuration (curvature).

(2) Template, a scaleless measuring instrument or layout device (pattern) for checking or outlining curved contours of shaped parts. It is used in machine building and shipbuilding. It is a steel plate with a working edge that describes the inverse (complementary) profile of an object. Measurements are usually made by estimating the width of the gap between the template and the object with a clearance gauge.
