This paper studies the rectification of a three-centered spiral plane curve and the determination of its true length. The curve is constructed from circular arcs with different radii, and the lengths of the arcs are determined using the method of small chords. The study shows the practical significance of geometric methods in engineering graphics and technical design, especially for spiral elements and complex curved components. Conference paper in Uzbek (with abstract and keywords in multiple languages).
