The apparatus has an evaluated value calculating meansfor calculating the complexity of the object shape and the complexity of the modeling structure of the object CAD data input by the CAD data inputting means; a searching meansfor searching the reference CAD data in the reference CAD data basein accordance with the condition of said complexity; an evaluated value calculating meansfor calculating the complexity of the object shape and the complexity of the modeling structure based on the searched reference CAD data; and a displaying meansfor evaluated values obtained by the meansand the meanson the graphic representation defining its horizontal axis for the complexity of the object shape and its vertical axis for the complexity of the modeling structure. It will be appreciated that the man-hour for evaluating large amount of various models can be reduced by means of not using a CAD system.
