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.
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 cen-
ter 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.
