<p>From a component model library 16 having stored therein a three-dimensional component model created for each type of component, a component model to be implemented is created. The component model is incorporated in a three-dimensional printed-board model created based on printed-board information, thereby creating an implemented-printed-board model. A low-component-shape deleting unit (30) deletes a low-component shape having a height up to a specified height from the component models stored in the component model library (16) to reflect the deletion results onto the implemented-printed-board model. A low-component-replacement model creating unit (32) creates and incorporates, based on a component implementation area of a printed board and the specified height, a single low-component-replacement model that replaces a deleted portion of the low-component shape, thereby creating a printed-board simplified model.</p> |
