Abstract
Disclosed is a shape data processing method illustratively for use with a CAD,CAM (computed aided design/ computer aided manufacturing) system. The method involves measuring the volume of a target product based on the shape data of that product. In operation, a virtual projection surface is established for the target object to be measured. The surface of the object is divided into small regions. A column portion is formed as an extension from each small region to the projection surface. The volume of the column portion is measured for each small region. The measured volumes are accumulated in accordance with the orientation of the normal vector to each small region. This method allows the volume of the target object to be measured easily and with precision even if the shape thereof is complex.
