CAD APPARATUS, METHOD OF EDITING GRAPHIC DATA, AND COMPUTER PRODUCT

摘要

A CAD apparatus and a computer readable recording medium recording a CAD program are provided to manage concrete history of design change and design information and to enable a designer or a third party to perform editing tasks efficiently while checking content of past design change. A CAD apparatus includes a layer displaying unit(152), a graphic element converting unit(158a), an element restoring unit(158b), and an element searching unit(156). The layer displaying unit displays elements included in each of layers that form graphic data onto a display unit in a superposed manner. The graphic element converting unit converts an element included in the first layer that forms the graphic data into a graphic element, and moves converted graphic element to the second layer that forms the graphic data. The element restoring unit restores a converted graphic element into a state before graphic element conversion. The element searching unit searches for an element that satisfies a certain condition from among elements included in the graphic data subjected to the processing. When a certain operation is performed at an input unit(120), the element searching unit displays an element search screen onto a display unit(110), searches for an element based on an input search condition received on the screen, and displays an element satisfying the search condition in a highlighted manner by changing a color of the element or flashing the element.
