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