Abstract. Abstract. Curve drawing procedures in traditional architecture and civil engineering in Japan are formulated in terms of western mathematics in order to abstract the fundamental form of the curves and to know what is attempted for its modifications. Confirming the human capability to discriminate such curves, the formations of the images are classified. Based on this framework, a hypothesis on the general characteristics of those curves is proposed: Image of the open ended symmetric curves with axes directed towards the objects of interests is intended and the realization of the impression of elasticity is also attempted.
