Planes mode allows you to make up to six sectional cuts in any plane while still being able to navigate around
the scene, enabling you to see inside models without hiding any item. By default section planes are created
through the center of the visible area of the model.
Section planes are stored inside viewpoints and so can also be used within viewpoint animations and object
animations to show a dynamically sectioned model. See “
Saved Viewpoints Window” on page 280 for more
information on viewpoints, and “
Record and Play Animations” on page 299 for more information on animations.
Box
mode enables you to focus your review on specific and limited areas of the model. As you move the
box around, only the geometry within the defined section box is displayed in the Scene View.
To turn sectioning on or off for the current viewpoint
■ Click Viewpoint tab ➤ Sectioning panel ➤ Enable Sectioning

Enable and Use Section Planes
To view cross-sectional cuts of your model, you can enable up to six section planes. When a plane is ‘enabled’
it means that it affects (cuts through) the scene. The current plane is the one that is rendered visibly in the Scene
View. Selecting a plane as current automatically enables that plane if it was not already enabled.
When a section plane is first enabled, it is created with the default alignment and position. Afterwards, enabling
a section plane restores the saved alignment, position, and rotation if it is available for the current viewpoint.
NOTE To save the settings for enabled section planes (alignment, position, rotation), you need to save the current
viewpoint with sectioning enabled and in sectioning mode.
