The purpose of this study is to clarify R. M. SCHINDLER's relations between plans, elevations and sections. As a result of extraction of volumes by the forms of the surfaces of walls from the axonometric plan, it's guessed that the forms of the walls connect independently of the plans. It's found that the surfaces of the walls which are divided by the plans, are dispersed. It's my opinion that the forms of the outer walls don't express the interior spaces by means of the interlocking volumes. These are reorganized by the surfaces of the walls, which are divided by the volumes of the surfaces of the walls and the volumes in the plans, combine the unevennesses of plans and sections on the same plane.
