Isolate Displays only the selected part, hiding all others.
Zoom To Part Changes the center focus from the entire 3D model to an individual part. This is especially useful
when rotating the part, allowing it to rotate around its own center focus rather than that of the entire model.
Transparent Displays a see-through version of the selected part.
Export As XML Creates a separate file of either Whole Tree or Current Node of the 3D model.
Set 3D views
The default view of a 3D model lets you quickly revert to a starting point at any time as you interact with the model.
A default view is different from a preview, which determines what the 3D model looks like when it’s not activated.

Open Model Tree On 3D Activation Determines whether the Model Tree is displayed when the 3D model is
activated. Choose Use Annotation’s Setting to use whichever setting the author used when adding the 3D model to
the PDF document.

Enable Double-Sided Rendering Some model parts have two sides. To save time and space, you can deselect this
option to render only the side facing the user. If the user looks inside a part rendered with only one side, the back
side would be invisible.
Enable Camera Animations Some 3D models include animations enabled by JavaScript. Deselect this option to
prevent 3D animation.
