PROBLEM TO BE SOLVED: To create parts library data by providing a hierarchical structure of selected and sorted features on the shapes of electronic parts and simply selecting the optimum format among plural formats. SOLUTION: When first 'part with lead' is selected in the first hierarchy, subsequently 'IC' is selected in the second hierarchy, and '90-degree arc direction lead' is selected in the third hierarchy, and 'one-direction lead' is selected in the fourth hierarchy, a CPU 20 displays the data input format for IC with a lead in one-direction on a monitor 36. Accordingly, at the end of inputting first 'the part dimensions' in the X and Y directions of the electronic part by a keyboard 34, and then 'lead direction', 'lead width', 'lead length', 'number of leads', 'lead pitch' and 'lead shape' by an operator, the parts library data on the part with the lead is created and stored in a RAM 22. |
