Chapter 3 Viewing and Displaying Three-Dimensional Models 57 Setting Views with the Compass The compass allows you to dynamically rotate the model in the XY plane. To do so, pick and hold on one of the four labels (N, S, E, or W). Then, drag the mouse to rotate the view. The view pivots about the Z axis of the current UCS. Try this a few times and notice that you can completely rotate the model by continuously moving the cursor off the screen. For example, pick the letter W and move the pointer either right or left (or up or down). Notice as you continue to move the mouse in one direction, the model continues to rotate in that direction. You can use the compass to display the model in a view plan to the right, left, front, or back face of the cube. When the pointer is moved to one of the four compass directions, the letter is highlighted, Figure 3-10A. Simply single pick on the compass label that is next to the face you wish to view. See Figure 3-10B. X axis is perpendicular to the view X axis is inclined to view Receding surfaces are visible A B Figure 3-8. A—To properly view orthographic faces using the view cube, turn on Perspective with Ortho Faces in the shortcut menu. B—When an orthographic view is set current with perspective projection on, the view is not a true orthographic view. Notice how you can see the receding surfaces. Figure 3-9. A—The selected orthographic face is surrounded by triangles. Pick one of the triangles to display that orthographic face. B—The orthographic face corresponding to the picked triangle is displayed. Picking a roll arrow rotates the current view 90° in the selected direction. C—The rotated view. Pick A B C Pick
