We have conducted to develop the computer assisted instruction system which provides an e-Learning environment for drawing practice. In this study, the methods to check on linear, circular, and angular dimensions were discussed. The validity of dimensional information on circle was evaluated by the presence of both dimension lines indicating the center point and the diameter. The validity of information on arc was also evaluated by the dimension line indicating the curvature. The linear dimensions, determined from circular and angular dimensions, were used for checking on dimension lines missing at the final stage of the proposed checking strategy. This strategy dose not required correct drawings so that one can do the learning without the help of teachers. The prototype system was developed and examples of execution were demonstrated.
