Because the first curves were designed in France!
Ludwig Burmester, a German geometer, invented the Burmester curve also known as the French curve.
french curve is used to connect arce and semi-circles, such as the neckline, armholes , and collar. it is either made of flat metal or wood.
A French curve is a tool used to draw different curves there are lots of swirls and circles so if a circle guide isn't good enough the French curve can draw and curves possible.
The French curve, or designer's curve, is used for creating garment patterns. Patterns are usually based on standardized sizes intended to fit what's considered to be average sizes.Standardized sizing don't fit everyone, which is why a French Curve is handy. The French Curve can be used to customize garment patterns, allowing sewers to adjust them to fit curvaceous figures or lower a neckline.Examples of uses of a French Curve:Fitting the hips in a skirt or pantsDarts for bustlinesArmholesLower the neckline
Straight lines.
une courbe
Kirvenlineale von Gebrüder
a curve is translated 'une courbe' (fem.) in French - plural: des courbes.
The french curve is a set of segments of Euler spirals, also known as clothoids. The curvature of a clothoid varies linearly along its length. If you start at the least curved end of one of the segments (curvature closest to zero) there will be a declining radius of curvature as you go until you reach the end of that segment. The french curve set has several segments with different rates of curvature change.
L-Square- to draw perpendicular lines Hip Curve- To shape skirt, slacksspecifically on the hiplines and hemlines,side seams and lapel. French Curve- To shape necklines, collars, and armholes
Basically, it IS a curve.
