Recently, design of cars and household appliances has mainly been carried out using various types of 3-D CAD systems. Although the 3-D CAD is superior for presenting the shape of the object, some problems are left unsolved. For example, it is widely recognized in the mechanical design field that conversion of a 3-D image to 2-D production drawings is not always adequate because the description of the measure is sometimes inaccurate. Under these conditions, correction of the drawings should be carried out one by one. Nevertheless, the use of 3-D CAD is rapidly increasing and, accordingly, educational institutions teaching 3-D CAD are increasing year by year. This paper reports on the introduction of 3-D CAD to descriptive geometry field. The objective of the present study is to improve the above-mentioned shortcoming of 3-D CAD on the measure description. Many kinds of problems encountered in descriptive geometry are solved using 3-D CAD.
