Animating Navigation As you navigate in Autodesk Navisworks, you can record viewpoint animations, and then play them back. For more information, see "Record and Play Animations" on page 251. Orientation in 3D Space Although Autodesk Navisworks uses the X, Y, Z coordinate system, there is no hard-and-fast rule as to which way each of these particular axes actually 'points'. Autodesk Navisworks reads the data necessary to map which way is 'up' and which way is 'north' directly from the files loaded into your scene. If this is not possible, by default, Z is treated as 'up' and Y is treated as 'north'. It is possible to change the 'up' and 'north' directions for the entire model (world orientation), and the 'up' direction for the current viewpoint (viewpoint up vector). NOTE Changing the viewpoint up vector affects navigation in modes that rely on the 'up' direction of the current viewpoint, such as walk, turntable, and orbit. It also has an impact on section views. To align the viewpoint up vector to the current view ➤ Click Viewpoint ➤ Set Viewpoint Up ➤ Set Up. To align the viewpoint up vector to one of the preset axes 1 Click Viewpoint ➤ Set Viewpoint Up. 2 Click one of the preset axis. Choose from: ■ Set Up + X ■ Set Up - X ■ Set Up + Y ■ Set Up - Y ■ Set Up + Z ■ Set Up -Z To change the world orientation 1 Click Tools ➤ File Options. 2 In the File Options dialog box, Orientation tab, enter the required values to adjust the model orientation. 126 | Chapter 6 Explore Your Model
