Navigation Cube/en

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 consists of a number of parts:
 * The main cube
 * Six directional arrows
 * The reverse view button (top right)
 * The mini-cube menu (bottom right)
 * X, Y and Z Axis indicators

All parts, except the axis indicators, can be clicked.

Main cube
The main cube has 26 faces: 6 main faces, 12 rectangular edge faces, and 8 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.

Mini-cube menu
Clicking the small cube in the bottom right corner of the Navigation Cube will bring up a menu with the following options:
 * : switches to an orthographic view.
 * : switches to a perspective view.
 * : switches to an isometric view.
 * : zooms and pans the camera so that all visible objects fit inside the view.

Move the Navigation Cube
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:. See Preferences Editor.

Advanced parameters
Some advanced Navigation Cube parameters cannot be changed in the Preferences Editor. These parameters can be set manually in the Parameter editor or via the CubeMenu external workbench. Changes will become visible when a new 3D view is created (with Std New, Std Open or Std ViewCreate).

To manually set colors:


 * 1) Start the [[Image:Std_DlgParameter.svg|16px]] Parameter editor.
 * 2) In the panel on the left browse to.
 * 3) Right-click the panel on the right and select  from the context menu.
 * 4) Enter the name of one of these colors:
 * : the lines separating the cube faces, default is (hex: ).
 * : all elements around the cube, default is (hex: ).
 * : all cube faces, default is (hex: ).
 * : the cube or arrow face that is currently highlighted, default is (hex: ).
 * : the text on the cube faces, default is (hex: ).
 * 1) The color value must be entered as a 32-bit unsigned integer. Translated to the hexadecimal format this integer has the form . Where  stands for the alpha channel (a measure for the transparency), and the other three digit pairs stand for red, green and blue. To convert a hexadecimal value to an unsigned integer you can use the Python console, enter for example, or an online service such as this one.
 * 2) Optionally set more colors.
 * 3) Press the  button.

To manually set the border width:


 * 1) Start the [[Image:Std_DlgParameter.svg|16px]] Parameter editor.
 * 2) In the panel on the left browse to.
 * 3) Right-click the panel on the right and select  from the context menu.
 * 4) Enter the name,.
 * 5) Enter the width.
 * 6) Press the  button.
