Problem Statement: Drafting course is essential for students in the design disciplines for becoming more organized and for complying with standards in the educational system. Drafting knowledge is crucial, both for comprehension of the issues and for the implementation phase. In any design project, drafting performance and success are as important as the design process, especially in the educational environments aimed at professional life. However, there have been relatively any studies undertaken in the area of the success and time saving of the conventional drafting and computer-aided drafting (CAD) techniques, besides the design process, especially for furniture and interior design educations. In this direction, some questions emerge in the study. Is there really a difference on quality, success and drafting time between conventional drafting and CAD techniques in interior drafting field? If there is a difference, at which time or process does the drafting technique gain speed?
