Triangles & Curves
French Curves are used in manual drafting, calligraphy, and fabric design to draw smooth curves of varying radii. The shapes are segments of the Euler spiral or clothoid curve. Flexible curves are used when an irregular curve is necessary. Our selection of aluminum and high impact plastic triangles are available in many sizes, and in either a 30/60 or 45/90 degree formats.
