A Study on Practical Educations of Technical Drawing by Personal-Computers

Drawing educations by the personal-computer were practiced in the junior high school and in the technological education in the university. At the lesson of "Basic Information" in the junior high school, the drawing education by personal-computers was introduced for the 2nd grade students. At lessons such as "Standard Drawing', "Machine Mechanisms", "Drawing Method part I", and "Machine Design and Production", the practical educations by the computer aided drawing (CAD) were prepared for students belonging to the department of technological education in the university. The CAD software was selected and bought for those school lessons. The operating manual was reformed more simply. At first, the computer aided drawing (CAD) was carried out by the third angle orthographic projection by the operating manual. Secondly, basic and application drawing educations by personal-computers were taken place in the computer practice room of the information processing center and in the machine practice room. Some problems which happened at practical lessons, above mentioned, were examined and discussed
