Enable and Use Section Box
You can use a section box to focus your review on specific and limited areas of the model. The section box can
be moved, rotated, and scaled with the sectioning gizmos, available from the Sectioning Tools tab ➤ Transform
panel. You can also manipulate the section box numerically.
By default, when a section box is enabled, the move gizmo is used, unless you have already selected a different
gizmo before activating the section box. All gizmos share the same location/rotation. This means that moving
one gizmo affects the position of others.
When the section box is first created, the default size of the box is based upon the bounds of the current viewpoint.
The box is created to fill the view such that no part of the box is drawn off-screen. Afterwards, enabling a section
box restores the saved position, rotation, and scale information used if it is available for the current viewpoint.
NOTE To save section box settings (position, rotation, size), you need to save the current viewpoint with sectioning
enabled and in box mode.
Quick Reference
The following table illustrates how the sectioning gizmos work with the section box.
BehaviorGizmo
You can use arms and faces to move both
the box and the gizmo itself in the relevant
axis.
Move
The position of the gizmo signifies the
center of rotation. Arcs rotate the box.
Arms move the gizmo only.
Rotate
You cannot move the transform center.
Pulling on any of the scale points scales
the box.
Scale
To use a box to cross-section a 3D model for the first time
1 Click Viewpoint tab ➤ Sectioning panel ➤ Enable Sectioning
.
Autodesk Navisworks opens the Sectioning Tools tab on the ribbon, and draws a section plane through the
model in the Scene View.
2 Click Sectioning Tools tab ➤ Mode panel ➤ Box
.
The box is now visually present on the screen, with the move gizmo enabled by default.
3 Drag the gizmo to box-section your model along the axes.
