Abstract: In this paper, a G1, C1, C2 PH-spline is employed as an approximation for a given bé;zier curve within error bound and further renders offset which can be regarded as an approximate offset to the bé;zier curve. The errors between PH-spline and the bé;zier curve, the offset to PH-spline and the offset to the given bé;zier curve are also estimated. A new algorithm for constructing offset to the bé;zier curve is proposed.
