Method of presentation null of each data in order to form the wiring path of the print patchboard

摘要

PURPOSE:To easily perform the design of a printed circuit board by displaying a conductor circuit or a through hole superimposed at each layer on the same screen by shifting a little. CONSTITUTION:An offset item is newly provided at wiring data to perform picture display so as not to hide data in each layer, and display is performed by applying offset on superimposed data. When the conductor circuit and the through hole are displayed comprehensively on the same screen based on, for example, the data in figure, the data of one layer is displayed on the screen in such a state where the offset is applied on the data inputted later. Thereby, it is possible to perform the design of the printed circuit board easily and with high efficiency by using simplified facility in the unconnected wiring processing of automatic wiring CAD or design CAD performed with direct input by using a picture.
