It is proposed for detailed breakdown of a circular curve from chords (secants), the rectangular coordinates of curve points are determined through their increments. The calculation of the rectangular coordinates of curve points through coordinate increments is advantageous because of the simplicity of such calculations, the possibility of calculating by known schemes, the possibility of applying the same scheme of calculating coordinates, and breaking the curve from chords and breaking the curve from the tangent.
