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.
