    • PURPOSE: An offset curve calculation method and its record media are provided to continuously interpolate the variation of the offset radius or to enable a user to set or control the variation of the offset radius by calculating an offset curve with a variable radius based on an approximate equation for a sweep operation. CONSTITUTION: A boundary line of an object, p(t), which is required in an offset sweep operation, is calculated(S10). A radius varied with respect to time, r(t), is calculated where r means a radius of an offset circle of the object and t means time(S20). Sampled values, ti, of the time variable t for controlling the variation of the curve radius are calculated(S30). A sweep approximate value of the offset curve with variable radius is calculated for continuously interpolating the variation of the offset curve radius by using the p(t), r(t) and ti(S40).
