This paper describes the effectiveness of box method for isometric drawing from orthographic views, used in traditional graphics instruction. For evaluation of effectiveness box frame displayed problems, suggested box method are provide. Student performance on these transformation problems delivered by CAI system is compared experimental (box frame displayed) with control groups. The following three variables were measured to determine teaching effectiveness: percent of correct answer, mean solution time for correct answer, and mean solution time for all subject. These variables indicate that the students who received the box frame displaying performed better in all measured areas. We have found that the effectiveness of box method is shown in these variables. Several factors of solution time for all subject were identified related to this improved performance. These obtained factors were time in beginning drawing, operation times, number of out-of-bounds line, and time expenditure per one operation.
