This study compared educational efficiencies among BIM (Building Information Modelling) tool, AEC CAD tool and freehand sketching to make architectural drawings and presentations. With four factors, that is, presentability, correctional ability, connectivity and legibility, presentational abilities to use each drawing-making tool are analyzed and also compared each data file size and finishing time. With the result of the study, BIM tool is better to make drawings and to present architectural idea than existing AEC CAD tool, and will helpful to develop design abilities as an CAD educational method.
