A CAD apparatus, and a computer readable recording medium recording a CAD program are provided to skip the same editing tasks at every page and to prevent an editor from forgetting edition tasks of partial pages. A CAD apparatus includes a layer information storage unit(141), a layer-state management unit(151) and a layer displaying unit(152). The layer information storage unit stores therein information that defines a superposing order, availability of display, and availability of edit of layers that form graphic data subjected to processing. When displaying a layer that is defined as available to be displayed, if the layer is an individual page layer that includes elements different per page, the layer displaying unit displays only elements associated with a page determined to be displayed from among elements included in the layer. If the layer is an all page common layer that includes elements common to all pages, the layer displaying unit displays all elements included in the layer. The layer-state management unit manages superposing orders, availability of display, and availability of edit of each of layers that form graphic data. When a certain operation is performed at an input unit(120), the layer-state management unit displays a layer control screen onto a display unit(110), and renews contents of a layer management table in accordance with an operation performed onto the screen. |
