Abstract

A wiring-model creating apparatus creates a three-dimensional model of a wiring pattern on a printed board based on printed-board information created by an electrical computer-aided design, as a wiring model for a mechanical computer-aided design. A three-dimensional-model creating unit creates the three-dimensional model including holes on the printed board in addition to the wiring pattern, based on the printed-board information.
