#### Symbols Tab

The Symbols tab of the CAD and Graphic Setup dialog box (Edit | Setup | Cad and Graphic Setup) lets you change how different symbols are displayed in the Graphics Display window.

Hint: You can also display this by clicking the Display Symbols icon from the Graphics Modes toolbar.

CAD and Graphic Setup dialog box—Symbols tab

The initial values for the settings on the Symbols tab come from the registry or hard-coded defaults.

Available symbols you can modify include Wireframe and Surface objects, the Point Symbol, the Arrow Symbol, and Path Lines. Corresponding areas exist on the Symbols tab. Whenever you make a change to one of the check boxes or option buttons, Planner will apply that change automatically so you can see what effect it will have. Planner will only save your changes once you click the OK button. To see changes to the symbols' sizes click the appropriate Apply button.

Dialog Box Item | Description
Draw for speed option | This option turns off anti-aliasing for wireframe and surface objects, optimizing the drawing speed of CAD objects in the Graphics Display window.
Draw for quality option | This option turns on anti-aliasing for wireframe and surface objects. This optimizes the drawing quality of CAD objects in the Graphics Display window.
Point Symbol drop-down list | This list defines the type of Point to modify. You can choose either CAD Point or Feature Point. The default item is Feature Point.
Diameter / Width in Pixels box | This box defines the size of the point symbol. Square Dot and Round Dot symbols use Width in pixels; 3 Lines and Sphere use Diameter in plan units. Note that the maximum size for Round Dot is based on the computer's physical video card. If the size exceeds the limits of the current computer's video card, it will simply display the symbol at the largest size available to the current system's video card.
Square Dot option button | This option displays the point symbol as a square dot. This is the quickest symbol for Planner to draw. Example Square Dot symbol
Round Dot option button | This option displays the point symbol as a round dot. Example Round Dot symbol Note: Square Dot and Round Dot symbols are drawn flat on the screen and may be clipped by the CAD model.
Three Lines option button | This option displays the point symbol as a three-lined cross hair. Example Three Lines symbol
Sphere option button | This option displays the point symbols as a sphere. This is the slowest symbol for Planner to draw, especially if you have all the attributes selected. These check boxes become available if you select the Sphere symbol. They provide you with additional attributes to further control the display of a sphere symbol in the Graphics Display window.

- Shaded - This check box produces a shaded (opaque) sphere symbol.

- Lighting - This check box adds OpenGL lighting to the sphere symbol.

- High Quality - This check box produces a smoother looking sphere symbol.

While these check boxes improve the image quality of the sphere symbol, they will also cause a slight increase in the time it takes to draw the sphere symbols whenever the screen gets refreshed.

Some Examples:

| - Shaded, High Quality
| - Lighting, High Quality
| - Shaded, Lighting, High quality

Arrow Symbol box | This box controls the diameter size (in plan units) of the arrows displayed in the Graphics Display window. The size of the actual arrow in the display will change only if the Shaded check box is selected. Shaded - This check box shades arrow symbols, in essence drawing arrows as cylinder tubes with a set diameter. If not selected, arrows are drawn as simple lines without size.

Some Examples:

| - Not Shaded
| - Shaded
| - Increased Diameter
