Abstract:
1. A computer-implemented method for creating shape data by using three-dimensional CAD, comprising the steps of: storing, in a database in advance, information of means which can used in operation of working or assembling and attributes of at least accuracy and cost of said operations of working assembling; selecting information of said means stored in said database in accordance with a shape of an object to be created based on shape data created from said means; determining attributes of accuracy and cost of the selected means if used by consulting said database; and calculating at least one of workability, cost and assembling efficiency of creating the shape of the object based the consulted attributes, wherein a procedure formed by operations is stored, at least one of addition or deletion of an operation and a change of an order of the operations in the stored procedure is executed and an evaluation value of an operation of a succeeding part of the order is determined in accordance with a value assigned to an operation at a preceding part of the order, and at least one of workability, cost and assembling efficiency is corrected and calculated from the evaluation value thus determined.
