Abstract

The steps for designing a complex object of design are centralized, and the setting for processing programs started with the steps is greatly simplified, so that the load on the designer is reduced, and errors in design are also reduced. To that end, in the event of designing an object of design by a plurality of steps, the plurality of steps are displayed on a CRT display, judgment is made whether execution thereof is possible, and based on that judgment, executable steps are displayed in green, and non-executable steps are displayed in red. Setting of the parts necessary for design, and the setting of CAD tools started in the steps is performed by keyboard or mouse, and the steps of which the state has change are identified, and the color thereof is changed.
