This paper presents a system to convert range data to 3D CAD data by the operator's interaction in 3D Virtual Space. Recently, although many researches have been done, it is difficult to obtain exact shapes for 3D CAD systems. Also, there are systems for the purpose by the operator. However, since using displays and pointing devices for 2D in them, the operator cannot operate on range data easily. To solve such problems, the authors utilize Virtual Reality Technology for converting range data to 3D CAD data, and have developed a prototype system for it. This system provides a suitable interface to select a part of range data and generate geometric shapes by using a stereoscopic display, 3D pointing device and various template cursors. In addition, by applying methods of pattern recognition to the selected points, we can obtain 3D CAD data efficiently and exactly. As a result of the experiments, this system can generates 3D shapes from range data, and its effectiveness is confirmed.
