You can render 3D views only.
Tip: To render a 2D view, create a 3D view that is oriented to a 2D view (such as a section view or elevation view). Right-click the
ViewCube, and click Orient To View or Orient to a Direction. For details, see
Specify the camera position in a 3D view.
If the Rendering dialog was open when the 3D view was last open in the current session, the dialog redisplays.
