When having determined that the input event from a client unit is the selection of an object, a server unit requests the client unit to transmit display area information that sets a display screen area on the drawing data. The server unit acquires the display area information transmitted from the client unit in response to the request. The server unit determines whether the area of the object selected on the drawing data fits in the display screen area corresponding to the acquired display area information. If having determined that the area of the object does not fit in the display screen area, the server unit changes the display area information so that the area of the object may fit in the display screen area and transmits the changed display area information to the client unit. The client unit displays the drawing data received from the server unit.
