## Applying Lighting and Materials to the CAD Display

CAD Lighting icon from the View | Toolbars | Graphics Modes toolbar | Selecting the CAD Lighting icon or the Edit | Graphics Display Window | Lighting, Materials menu option displays the CAD and Graphic Setup dialog box.

CAD and Graphic Setup dialog box

The CAD and Graphic Setup dialog box gives you a set of tools that allow you to further manipulate the display of CAD models—including your part model, probe model, machine model, and other fixture models—inside PC-DMIS's Graphics Display window. You can also use it to change other properties that affect how things are drawn on the screen.

This dialog box contains these tabs:

Archive: This tab lets you save and recall these CAD configurations for later use.

Lighting: This tab lets you define and enable light sources, their colors, their directions, light models, and CAD transparency.

Material: This tab lets you apply texture mapping to the surfaces of your CAD models, you can also change the colors and brightness of the materials making up the textures.

Clip Planes: This tab lets you define up to four Clipping Planes that hide your part model in the clipped area. You can use this to cut your part model to show cross sections and cutaway views.

Trihedron: This tab lets you modify the colors of each axis and component of the trihedron symbol.

Symbols: This tab lets you set properties for the display of wireframe and surface objects, point symbols and path lines.

Colors: This tab lets you define the screen's background color, the highlight color, the mouse-over highlight color, the 3d grid color, and Vision's Field of View (FOV) color.

OpenGL: This tab lets you define OpenGL options that affect the display of the model in solid view mode.

There are four buttons at the bottom of the dialog box:

OK – Accepts your changes and closes the dialog box.

Cancel – Rejects your changes and closes the dialog box.

Save System Defaults – Saves your changes as the new default lighting and material settings. This overwrites the default settings that came with PC-DMIS.

Restore System Defaults – This brings back the original lighting and material settings that came with PC-DMIS.

Note: Any modifications you make to the CAD and Graphic Setup dialog box take place in real time in the Graphics Display window. This lets you immediately see the effects of your selected changes. Until you click OK, however, the changes you make are only temporary.
