+# 3D View
 
-## Introduction
-
-
-
-The [3D view](3D_view.md) of FreeCAD is an instance of a Coin3D [scenegraph](Scenegraph.md) that forms the most important window in the [interface](interface.md). Coin3D is a library that implements the OpenInventor 2.1 scene description standard.
-
-Certain properties of the view, like background color, [mouse navigation](Mouse_navigation.md) style, and zooming steps, can be configured in the [preferences editor](Preferences_Editor.md).

-
-
-*The [Draft Workbench](3D_view]]_is_a_component_of_the_FreeCAD_[[interface]]. By default it shows a small widget with coordinate axes, and the navigation cube also with coordinate axes; the grid can be displayed and configured by loading the [[Draft Workbench.md).*
-
-## Actions
-
-
-**Note:**
-
-link actions <small>(v0.19)</small> .
-
-Since the [tree view](tree_view.md) lists most objects that are visible in the 3D view, many of the actions are the same to those that can be executed from the [tree view](tree_view.md).
-
-When the default [Start Workbench](Start_Workbench.md) is active, right clicking on the 3D view shows only one command:
-
--    **[Navigation styles](Mouse_navigation.md)**: different button styles to use with a 3-button mouse or laptop trackpad.
-
-However, once a [Workbench](Workbenches.md) is loaded, there are additional commands:
-
--    **Link actions**: [Make Link](Std_LinkMake.md).
-
-    -   
-        **Make Link group**
-        
-        : [Simple group](Std_LinkMakeGroup.md), [Group with links](Std_LinkMakeGroup.md), [Group with transform links](Std_LinkMakeGroup.md).
-
--    **[Fit all](Std_ViewFitAll.md)**: pans and zooms the view to fit all objects in the document on the screen.
-
--    **[Fit selection](Std_ViewFitSelection.md)**: pans and zooms the view to tightly fit the currently selected object on the screen.
-
--    **[Draw style](Std_DrawStyle.md)**: as is, flat lines, shaded, wireframe, points, hidden line, no shading.
-
--    **[Standard views](Std_View_Menu.md)**: [isometric](Std_ViewIsometric.md), [front](Std_ViewFront.md), [top](Std_ViewTop.md), [right](Std_ViewRight.md), [rear](Std_ViewRear.md), [bottom](Std_ViewBottom.md), [left](Std_ViewLeft.md), [rotate left](Std_ViewRotateLeft.md), [rotate right](Std_ViewRotateRight.md).
-
--    **Measure**: [toggle measurement](View_Measure_Toggle_All.md), [clear measurement](View_Measure_Clear_All.md).
-
--    **Document window**: [docked](Std_ViewDockUndockFullscreen.md), [undocked](Std_ViewDockUndockFullscreen.md), and [fullscreen](Std_ViewDockUndockFullscreen.md).
-
-Additionally, depending on the workbench and object that is active, other contextual commands may become available.
-
-For example, with the [Part Workbench](Part_Workbench.md) and one object selected:
-
--    **[Appearance](Std_SetAppearance.md)**: launches the dialog to change color and sizes of lines and vertices, and color of faces.
-
--    **[Toggle visibility](Std_ToggleVisibility.md)**: makes the object visible or invisible in the 3D view.
-
--    **[Toggle selectability](Std_ToggleSelectability.md)**: makes the object no longer selectable in the 3D view; use again this command to cancel its effect. It sets the object\'s `Selectable` attribute to `True` or `False`. Change the property by toggling **Selectable** in the [property editor](property_editor.md).
-
--    **[Go to selection](Std_TreeSelection.md)**: expand the [tree view](tree_view.md) to show the selected object in the hierarchy.
-
--    **[Random color](Std_RandomColor.md)**: assigns a random color to the object. It sets the object\'s `ShapeColor` attribute to a tuple `(r,g,b)` with tree random floats between 0 and 1. Change the property by modifying **Shape Color** in the [property editor](property_editor.md).
-
--    **[Delete](Std_Delete.md)**: removes the object from the document, and from the 3D view, by calling the document\'s `removeObject()` method.
-
-Another example, with the [Draft Workbench](Draft_Workbench.md) and one object selected, it shows the same commands as with the [Part Workbench](Part_Workbench.md), but also:
-
--    **Draft**: object creation and modification commands from the [Draft Workbench](Draft_Workbench.md).
-
--    **Utilities**: additional contextual commands provided by the [Draft Workbench](Draft_Workbench.md).
-
-## Details
-
-FreeCAD uses the Quarter library to use Coin3D in a Qt environment.
-
-It is possible to interact directly with the 3D view scenegraph from the [Python console](Python_console.md) by using the Python library Pivy.
-
-For more information see the power user documentation:
-
--   [Scenegraph](Scenegraph.md), description of Coin3D.
--   [Pivy](Pivy.md), usage of Coin3D from the Python console.
