5 Click Sectioning Tools tab ➤ Transform panel and click the sectioning gizmo you want to use (move
, rotate , or scale ). By default, the move gizmo is used.
Drag the gizmo to adjust the initial position of the section box in the Scene View.
6 Click Capture Keyframe
on the Animator toolbar to create a keyframe with the initial position of the
section box.
7 In the timeline view, move the black time slider to the right to set the desired time.
8 Use the gizmo again to adjust the depth of your cross-section cut.
9 To capture the current section box changes in a keyframe, click Capture Keyframe
on the Animator
toolbar.
Work with Keyframes
Keyframes are used to define position and properties of the changes made to the model.

Capture Keyframes
New keyframes are created by clicking Capture Keyframe
on the Animator toolbar. Every time you click this
button, Autodesk Navisworks adds a keyframe of the currently selected animation set, camera, or section plane
set at the current position of the black time slider.
Conceptually, keyframes represent relative translations, rotations and scaling operations from the previous
keyframe or, in the case of the first keyframe, the model’s starting position.
Keyframes are relative to each other and to the model’s starting position. This means that if an object is moved
in the scene (when, for example, a new version of the model is opened, or if movement tools are used in
Navisworks), the animation is done relative to the new starting location rather the animation’s original start
position.
The translation, scaling and rotation operations are cumulative. This means if a particular object is in two
animation sets at the same time, both sets of operations are carried out. So if both are translating across the X
axis, for example, the object will move twice as far.
If there is no keyframe at the start of the timeline for an animation set, camera, or section plane set, then the
very start of the timeline acts like a hidden keyframe. So, for example, if you have a keyframe a few seconds in,
and the frame has the Interpolate option enabled, then over those first few seconds objects would interpolate
between their default starting position and those defined in the first keyframe.
Edit Keyframes
You can edit captured keyframes for animation sets, cameras, and section plane sets.
To edit a keyframe
1 If the Animator window is not already open, click Animation tab ➤ Create panel ➤ Animator
.
2 Right-click the desired keyframe in the timeline view, and select Edit on the shortcut menu.
3 Use the Edit Key Frame dialog box to adjust the animation.
4 Click OK to save your changes or Cancel to exit the dialog box.
