The Chokuhotai-Bunkatsu-Zu, in Japanese, mean figures which represent how to partition a rectangular prism into some small rectangular prisms. So this is a model of a building which forms of outside view and inside rooms are both rectangular prisms. In planning processes, it is possible to obtain a reasonable outline plan of a rectangular prismatic building by means of allocation of proper floor spaces and heights of each room to proper C. B. Z. which is in match with initial planning conditions. Therefore it is useful to generate with a digital computer to stock these C.B.Z. as far as possible. In this paper a C.B.Z. is put upon 3 dimensional grids and inner partition planes which are put upon each grid plane are not allowed to intersect crosswise one another. As the C.B.Z. is only utilized to the space allocation, generality is not miss on account of this rule. When a number of partition is given, each number of unit of X, Y and Z direction of a grid which includes a C.B.Z. is able to be decided. Surplus partition planes which form the grid are pulled out under the rule of partition plane joints and the grid becomes a C.B.Z. Mirror image and rotation are utilized to eliminate similar patterns. A program which is encoded of this procedure with FORTRAN IV is showed in Figure-6. This is available as a foundation of a total system which is able to generate reasonable outline plans of a building automatically through a digital computer.
