Framerate Threshold Sets the minimum framerate, either by dragging the slider or entering a number in the value
box. If the framerate drops below that number of frames per second, the Optimization Scheme For Low Framerate
option goes into effect.
Comment on 3D designs
Comments added to a 3D object are associated with specific views that are defined when the comments are added.
If the view is changed—for example, if the 3D object is rotated or moved—the comments are no longer visible.
Note: Adding comments to 3D model views requires version 7.0.7 or later of Acrobat or Reader.
When the view of a 3D object is changed, any comment associated with that object disappears (right).
If you don’t want a comment to be associated with a 3D view, add the comment to another part of the page, outside
the 3D object area.

Add comments to a 3D object
Note: Adobe Reader users can add comments to a PDF if the document author enables commenting for that PDF.
1 Select a tool from the Comment & Markup toolbar. (The Text Edit tools have no effect on 3D objects.)
2 Click inside the 3D object area to create a new comment and also a new view definition in the Model Tree with a
default name such as “CommentView1.”
3 To add more comments, do one of the following:
• To create an additional comment in a view, make sure that the commenting view you want is selected in the Model
Tree, and click inside the 3D object area.
• To create an additional comment in a new commenting view, make sure that no commenting view is selected in
the Model Tree, and click inside the 3D object area.
