<p>PURPOSE:To arrange a body in an optimum state by the easy and instinctive specification of restriction conditions by specifying an elastic force between individual bodies and/or a body and a point in a space and moving the body according to the elastic force. CONSTITUTION:When a body in a rectangular shapes is handled, there are two modes and in a 1st mode, an operator can freely vary the attributes of the bodies. In and mode, the body is put in free motion according to the physical rule and the attributes change as the body moves. Namely, a room RM1 wherein the body is laid out is prepared and the body BX1 is placed in this room. Then a corner A of the room RM1 and a corner of the body BX1 are restrained with a segment KJ1 and in the 2nd mode, the body BX1 is so moved as to satisfy the restriction conditions. Thus, the restriction conditions connecting two points are a virtual spring whose length is 0 in its natural state and this spring has the elastic force for putting two separate points into one point.</p> |
