The '''Navigation Cube''' gives visual information about the camera orientation in the current [[3D_view|3D view]] and can be used to change it. By default it is visible and resides in the upper right corner of the view. |
||
The Navigation Cube was updated in FreeCAD version 0.20 and the rest of this page describes that version. In FreeCAD version 0.19 the main behavior is the same but some features are missing. |

The Navigation Cube consists of a number of parts: |
||
* The [[#Main_cube|main cube]] |
|||
*Directional Arrows |
|||
* Six [[#Directional_arrows|directional arrows]] |
|||
*Main Navigation Cube |
|||
* The [[#Reverse_view_button|reverse view button]] (top right) {{Version|0.20}} |
|||
*Mini-cube Menu |
|||
* The [[#Mini-cube_menu|mini-cube menu]] (bottom right) |
|||
* X, Y and Z Axis indicators |
|||
All parts, except the axis indicators, can be clicked. |

Hovering the mouse pointer over a feature of the navigational cube turns the feature light blue; clicking will reorient the 3D view as indicated by the feature. In the example below, the 3D view has been rotated by a [[Mouse_navigation|mouse gesture]] to a "non-standard" orientation. The pointer is over a corner (indicated by the blue color); clicking will reorient the 3D view to a standard axonometric view with that corner facing you. |

The main navigation cube ("nav cube" in the rest of this section), tracks the orientation of the actual object in the main part of the 3D view. Any operation which reorients the main 3D view will reorient the nav cube as well. |

The navigation cube is essentially a 3D view of a cube with its three main component types (faces, edges, and corners) enhanced so they may be easily clicked with the pointer. Clicking on a particular component will set the 3D view to have that component centered and facing you. The navigation cube is somewhat "squashed", as if the feature farthest from you were larger than the feature directly facing you. This allows the features adjacent to the feature facing you to be seen and consequently selected. |

Clicking the small cube in the bottom right corner of the Navigation Cube will bring up a menu with the following options: |

For example, in a "normal" view of a regular cube, when one face is facing you, you can also see the four edges of that face and the four corners of that face. In the "squashed" nav cube, you can also see features representing each of the adjacent faces, the four edges connecting the corners of the face facing you with the opposite face, and the corners of opposite face. This allows you to select any of the possible standard views except the opposite face and its edges (21 out of 26 possible views): |
|||
* {{MenuCommand|[[Std_OrthographicCamera|Orthographic]]}}: switches to an orthographic view. |
|||
* The face facing you (does nothing, since that is the current view) |
|||
* {{MenuCommand|[[Std_PerspectiveCamera|Perspective]]}}: switches to a perspective view. |
|||
* The four edges of the current face |
|||
* {{MenuCommand|[[Std_ViewIsometric|Isometric]]}}: switches to an isometric view. |
|||
* The four corners of the current face |
|||
* {{MenuCommand|[[Std_ViewFitAll|Zoom to fit]]}}: zooms and pans the camera so that all visible objects fit inside the view. |
|||
* The four adjacent faces |
|||
* The four edges leading to the opposite face |
|||
* The four corners of the opposite face |

Not possible: |

* The opposite face |

* The edges of the opposite face |

Note: As of this writing (v 0.18), there are some problems with the nav cube; not all features are currently selectable. In particular, edges are not selectable, nor are the four corners of the immediately facing face. |

Clicking on a face will orient the 3D view with that particular face facing you. From a face view, other selection points are available as noted above. There are four thin "bars" on each of the outside edges, representing the four adjacent faces; clicking them will select the view corresponding to the adjacent face. There are four round corners which may be used to set the corresponding axonometric view. There is also an interior set of edges and corners, which are currently non-functional. |

=== Edge Selection === <!--T:50--> |

Unfortunately, edge selection is currently broken. Attempting to select an edge will select the face which lies behind it. Clicking an edge should center that edge so it is facing you. |

Clicking one of the corners will give you an axonometric view as seen from that corner. As noted above, currently when a face is directly facing you, the corners of that face are not selectable. |

Introduction
The Navigation Cube gives visual information about the camera orientation in the current 3D view and can be used to change it. By default it is visible and resides in the upper right corner of the view.
The Navigation Cube was updated in FreeCAD version 0.20 and the rest of this page describes that version. In FreeCAD version 0.19 the main behavior is the same but some features are missing.
The Navigation Cube consists of a number of parts:
- The main cube
- Six directional arrows
- The reverse view button (top right) introduced in version 0.20
- The mini-cube menu (bottom right)
- X, Y and Z Axis indicators
All parts, except the axis indicators, can be clicked.
Usage
Main cube
The main cube has 26 faces: 6 square main faces, 12 rectangular edge faces (introduced in version 0.20), and 8 triangular corner faces. Clicking any of them will reorient the camera so that its direction is perpendicular to the selected face.
Directional arrows
There are six directional arrows: four triangular arrowheads and two curved arrows. Clicking one of the triangular arrows will rotate the 3D view around a line perpendicular to the direction of the arrow. Clicking a curved arrow will rotate the 3D view around the view direction.
Reverse view button
Clicking the round button in the top right corner of the Navigation Cube will rotate the 3D view 180 degrees around the vertical axis of the view.
Clicking the small cube in the bottom right corner of the Navigation Cube will bring up a menu with the following options:
- Orthographic: switches to an orthographic view.
- Perspective: switches to a perspective view.
- Isometric: switches to an isometric view.
- Zoom to fit: zooms and pans the camera so that all visible objects fit inside the view.
Customization
The entire Navigation Cube can be moved by pressing the mouse anywhere on the main cube and dragging. The structure will not begin to move until the cursor moves beyond one of the edges of the main cube.
Preferences
The Navigation Cube is controlled by several preferences: Edit → Preferences... → Display → Navigation → Navigation cube. See Preferences Editor.
Advanced options
The CubeMenu external workbench provides easier access to several more advanced customization options.
