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:

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

Usage

Main cube

The main cube has 26 faces: 6 main faces, 12 rectangular edge faces (introduced in version 0.20), and 8 corner faces. Clicking any of them reorients 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 rotates the 3D view around a line perpendicular to the direction of the arrow. Clicking a curved arrow rotates the 3D view around the view direction.

Reverse view button

Clicking the round button in the top right corner of the Navigation Cube rotates 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 brings up a menu with the following options:

  • Orthographic view: switches to an orthographic view.
  • Perspective view: switches to a perspective view.
  • Isometric: switches to an isometric view.
  • Fit all: zooms and pans the camera so that all visible objects fit inside the view.
  • Movable navigation cube: if this checkbox (introduced in version 0.21) is checked the entire Navigation Cube can be moved by holding down the left mouse button anywhere on the main cube and dragging. This is intended to temporarily move the cube out of the way. The advanced parameters OffsetX and OffsetY can be used to permanently reposition the cube, see below.

Customization

Preferences

The Navigation Cube is controlled by several preferences: Edit → Preferences... → Display → Navigation → Navigation cube. 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.

To manually set colors:

  1. Start the Parameter editor.
  2. In the panel on the left browse to BaseApp → Preferences → NaviCube.
  3. Right-click the panel on the right and select New unsigned item from the context menu.
  4. Enter the name of one of these colors:
    • BaseColor: the base color of all elements, the default is 3806916544 (hex: e2e8efc0). This color can be also set in the Preferences Editor. introduced in version 0.21
    • EmphaseColor: the color of the texts and lines, the default depends on the BaseColor. It is either black: 255 (hex: 000000ff), or white: 4294967295 (hex: ffffffff). introduced in version 0.21
    • HiliteColor: the color used to highlight the faces and buttons, the default is 2867003391 (hex: aae2ffff).
  5. The color value must be entered as a 32-bit unsigned integer. Translated to the hexadecimal format this integer has the form RRGGBBAA. Where AA 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 int("323232ff", 16).
  6. Optionally set more parameters.
  7. Press the Close button.

The table below lists the other advanced Navigation Cube parameters that can be set in a similar manner. Use the information from the Type column to create a correct new item in step 3.

Name Description Type Default
BorderWidth The width of the edges of the cube and the borders around the buttons in pixels. Float 1.1
ChamferSize The size of the edges and corners as a factor of the cube size. Values should be in the 0.05 - 0.18 range.

introduced in version 0.21

Float 0.12
FontStretch The font width as a percentage of the default width. Use 0 or 100 for the default font width. Integer 0
FontWeight The font weight. Higher values make the font more bold. The effect may depend on the font. Use 0 for the default font weight. Integer 0
FontZoom The size of the labels:
  • FontZoom = 1.0: Make the labels as big as possible individually.
  • 0.0 < FontZoom < 1.0: Idem but limit the maximum font size.
  • FontZoom = 0.0: Idem but use the same font size for all.
  • FontZoom < 0.0: Use the same font size for all, but scaled down.

introduced in version 0.21

Float 0.3
OffsetX The offset of the cube in the X direction relative to its corner position in pixels. Integer 0
OffsetY The offset of the cube in the Y direction relative to its corner position in pixels. Integer 0
ShowCS Toggles the display of the coordinate system (the X, Y and Z axis indicators). Boolean true
TextBottom The text on the bottom face of the cube. The default value should be translated. String BOTTOM
TextFront The text on the front face of the cube. Idem. String FRONT
TextLeft The text on the left face of the cube. Idem. String LEFT
TextRear The text on the rear face of the cube. Idem. String REAR
TextRight The text on the right face of the cube. Idem. String RIGHT
TextTop The text on the top face of the cube. Idem String TOP
