     \title Adding 3D Views
 
-    You can use a wizard to create a Qt Quick 3D UI project that imports
-    the \l{Qt Quick 3D} QML types to the \uicontrol {QML Types} tab in
-    \uicontrol Library and contains a 3D view, scene light, camera, and
-    model. A default material is attached to the model. You can attach
-    textures to materials. For more information about creating projects,
-    see \l{Creating Projects}.
+    To create a Qt Quick 3D UI project, we recommend using a \uicontrol
+    {Qt Quick 3D Application Template} wizard template that imports the
+    \l{Qt Quick 3D} QML types to the \uicontrol {QML Types} tab in
+    \uicontrol Library and contains a 3D view. A 3D view type includes a
+    \l {Setting Scene Environment}{scene environment} as well as a scene
+    \l {Using Lights}{light}, \l {Using Scene Camera}{camera}, and \l {Adding
+    Models}{model}. A default \l {Using Materials and Shaders}{material} is
+    attached to the model. You can attach \l {Attaching Textures to Materials}
+    {textures} to materials. For more information about creating projects, see
+    \l{Creating Projects}.
 
     To add a 3D view to some other kind of project and to display the Qt Quick
     3D QML types in \uicontrol Library, select \uicontrol Library >
     \uicontrol {QML Imports} > \uicontrol {Add Import} > \uicontrol QtQuick3D.

-    To add components to the scene, drag and drop them to \uicontrol Navigator
-    or \uicontrol {Form Editor}.
+    After importing the Qt Quick 3D QML types, drag and drop a \uicontrol
+    View3D type to \uicontrol Navigator or to \uicontrol {Form Editor}.

-    By default, a directional light and a perspective camera are used.
-    To use other light and camera types, change the type of the component
-    in the \uicontrol Type field in \uicontrol Properties. For example,
-    to use a point light, enter \e {PointLight}.
+    By default, a directional light and a perspective camera are used in a 3D
+    scene created by using the wizard template mentioned above. To use other
+    light and camera types, select the component in \uicontrol {3D Editor} or
+    \uicontrol Navigator and change the type of the component in the \uicontrol
+    Type field in \uicontrol Properties. For example, to use a point light,
+    enter \e {PointLight}.

-    To edit component properties, select the component in
-    \uicontrol {Form Editor} or \uicontrol Navigator and
-    modify the property values in \uicontrol Properties.
+    Similarly to other components, you can select a 3D view in \uicontrol
+    Navigator or \uicontrol {3D Editor} and modify its property values in the
+    \uicontrol Properties view. Use the properties in the \uicontrol View3D
+    tab to set some properties specific to a 3D view component.

-    For more information about the available components and their properties,
-    see \l{Using 3D Components}.
+    The \uicontrol Camera property defines which camera is used to render the
+    scene to \uicontrol {Form Editor}. If this property is not defined, the
+    first enabled camera in the scene will be used.
+
+    The \uicontrol Environment property specifies the \uicontrol
+    {Scene Environment} used to render the scene. By default, the first
+    \uicontrol {Scene Environment} in the scene is set as the property value.
+
+    The \uicontrol {Import Scene} property defines the ID of the component to
+    render to \uicontrol {Form Editor}. The component does not have to be a
+    child of a 3D view type. This referenced component becomes a sibling to
+    child items of a 3D view, if there are any. You can use this property, for
+    example, to create a split screen view showing your scene from multiple
+    cameras. For more information on how to to use a 3D view to show a scene
+    from multiple cameras, see \l {Qt Quick 3D - View3D Example}.
+
+    \note The \uicontrol {Import Scene} property can only be set once.
+    Subsequent changes will have no effect.
