摘要：In this paper problem for converting a circular arc into cubic Bezier arc and approximation of cubic Bezier curve by a set of circular arcs are discussed. These questions occur in CAD/CAM systems during data exchange from data formats which support Bezier curves or during data exchange into data formats, which do not support Bezier curves. Some simple and practical solutions are proposed. An algo-rithm for approximation of a cubic Bezier curve and the results of its testing are presented.
