概要

Recently, computer-aided design (CAD) systems are being used for total design from conceptual design to detailed design. Designers desire a CAD system which can draw their image faithfully. However, it is considerably difficult to modify the drawn curve in the present popular CAD systems. In this study, we developed a new local modification method for a B-spline curve by performing an inverse transformation of the B-spline curve. The influential range of each control point becomes narrow because of the increase of the number of control points, so that it is possible to modify the curve locally with mathematical smoothness. Furthermore, our developed method was linked to the general CAD and its availability was confirmed from the standpoint of execution time and handling.
