An information processing apparatus displays a shape of an object on a display device by using numerical values on a coordinate axis. The apparatus includes a calculating unit that calculates a minimum rectangular parallelepiped including the component by using numerical values indicative of a shape of the component; an outer-shape calculating unit that replaces every component constituting the object and calculates numerical values indicative of an outer shape of an object formed by collecting every replaced component into one; a determining unit that determines whether the component makes contact with the outer shape by using the numerical values indicative of the outer shape and the numerical values indicative of the shape of the component; and a displaying unit that displays on the display device an object composed of only components as making contact.
