## Changing Trihedron Colors

The Edit | Graphics Display Window | Trihedron Colors... menu item displays the Trihedron tab of the CAD and Graphic Setup dialog box.

CAD and Graphic Setup dialog box - Trihedron tab

This lets you change the colors of the different components of the part alignment trihedron that appears inside the Graphics Display window. You may find this useful when the background color or other items on the Graphics Display window have similar colors, making it difficult to see the trihedron; or perhaps you just want to give each axis a different color to easily differentiate between the axes.

The original colors for the trihedron symbol are red and green like this:

You can easily change these colors by clicking on the colored boxes in the Colors area and choosing a new color from the resulting Color dialog box:

As soon as you click OK, the Color dialog box closes, and PC-DMIS instantly updates the color of the trihedron accordingly in the Graphics Display window. When you click OK on the CAD and Graphic Setup dialog box, PC-DMIS will store the color information in the registry, so that all part programs will use these colors for the part alignment trihedron.

Colors area

The Colors area contains a grid of colored boxes representing the different components for each of the three axes of the trihedron.

Colors area

- Text - This sets the colors of the "X", "Y", or "Z" letters (or text) displayed on the trihedron (1 in image at right).

- Cylinder - This sets the color of the X, Y, or Z axis line (or cylinder) on the trihedron (2 in image at right).

- Cone - This represents the color of the Z, Y, or Z arrow head (or cone) on the trihedron (3 in image at right).

For example, changing the Text colors to blue, the Cylinder colors to pink, and the Cone colors to orange would result in a trihedron like this:
