Introduction

O controle do cubo de navegação, ou 'cubo de navegação, é uma ajuda gráfica de interface com o usuário para reorientar a visualização 3D. Por padrão, ele é visível e reside no canto superior direito da tela 3D. Se você estiver olhando para a vista 3D padrão, ela se parece com o seguinte:

O cubo de navegação é composto de várias partes:

  • Setas direcionais
  • Cubo de navegação principal
  • Menu mini-cubo

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.

Setas direcionais

Há seis setas direcionais: quatro setas triangulares, na parte superior, inferior, esquerda e direita; e duas setas curvas, uma de cada lado da seta superior.

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.

Menu mini-cubo

No canto inferior direito do cubo de navegação está um pequeno cubo. Clicando neste cubo, aparecerá um menu que você pode usar para mudar o tipo de vista (Ortográfica, Perspectiva, Isométrica) e para "Zoom to Fit".

Customization

Preferences

O cubo de navegação é configurável, incluindo o ajuste de seu tamanho: Editar → Preferências... → Tela → Navegação → Cubo de Navegação introduced in version 0.19.

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.
