Chapter 3 Viewing and Displaying Three-Dimensional Models 73 Display Features The Display area of the Steering Wheels Settings dialog box controls two features of the wheel display. These settings determine whether messages and tooltips are displayed. When a tool is selected, its name is displayed below the cursor. In addition, some tools have features or restrictions that can be indicated in a tool message. To see these messages, the Show tool messages check box must be checked. Otherwise, the messages are not displayed, but the restrictions remain in effect. A tooltip is a short message that appears below the wheel when the cursor is hovered over the wheel. When the Show tooltips check box is checked, you can hold the cursor stationary over a tool for approximately three seconds and the tooltip will appear. Then, as you move the cursor over tools in the wheel, the appropriate tooltip is immediately displayed. Walk Tool By default, when the Walk tool is used, you move parallel to the ground plane. This is because the Constrain movement angle to the ground plane check box is checked. Test this by selecting the Walk tool and then move the cursor toward the top of the screen. You appear to be “walking” over the top of the model. Now, open the Steering Wheels Settings dialog box and uncheck the Constrain movement angle to the ground plane check box. This allows you to “fl y” in the direction the cursor is moved when using the Walk tool. Exit the dialog box and again select the Walk tool. Move the cursor toward the top of the screen. This time it appears that you are fl ying directly toward or into the model. A B C Figure 3-29. The opacity of a steering wheel can be changed. A—Opacity of 25%. B—Opacity of 50%. C—Opacity of 90%.
