Os estilos de navegação do FreeCAD consistem nos comandos usados para navegar visualmente no espaço 3D e interagir com os objetos mostrados. O FreeCAD suporta multiplos estilos de navegação. O predefinido é o chamado "Navegação CAD", e é muito simples e prático, mas o FreeCAD também disponibiliza estilos de navegação alternativos, que pode escolher de acordo com as suas preferências.

Navegação

O manuseamento dos objetos é comum a todas as bancadas de trabalho. As combinações de comandos seguintes podem ser utilizadas para controlar a posição dos objetos e as vistas de acordo com o estilo de Navegação selecionado.

Existem duas maneiras de mudar o estilo de navegação:

  • No Editor de Preferências, Secção Visualização, separador Vista 3D;
  • Clicando com o botão direito do rato numa área vazia na vista 3D, e selecionando Estilo de Navegação no menu de contexto.


Navegação CAD (predefinido)

Este é o estilo de navegação predefinido e permite ao utilizador um controlo simples da visualização, e não requer o uso do teclado excepto para fazer múltiplas seleções.

{{{Select_name}}} {{{Pan_name}}} {{{Zoom_name}}} {{{Rotate_view_name}}} {{{Rotate_view_alt_name}}}
{{{Select_text}}} {{{Pan_text}}} {{{Zoom_text}}} {{{Rotate_view_text}}} {{{Rotate_view_alt_text}}}
{{{Ctrl}}}+ {{{Ctrl}}}+{{{Shift}}}+ {{{Shift}}}+
{{{Pan_mode_text}}} {{{Zoom_mode_text}}} {{{Rotate_view_mode_text}}}


Navegação Inventor

Na Navegação Inventor, criada a partir do Open Inventor (não confundir com Autodesk Inventor), não existe seleção apenas com o rato. Para poder selecionar objetos, é necessário pressionar a tecla CTRL. Template:Inventor Navigation


Blender Navigation

In Blender Navigation, modeled after Blender, there is no mouse-only panning. In order to pan the view, you must hold down the SHIFT key.

{{{Select_name}}} {{{Pan_name}}} {{{Zoom_name}}} {{{Rotate_view_name}}}
{{{Shift}}}+
{{{Select_text}}} {{{Pan_text}}} {{{Zoom_text}}} {{{Rotate_view_text}}}


Touchpad Navigation

In Touchpad Navigation, neither panning, nor zooming, nor rotating the view, are mouse-only (or touchpad-only) operations.

{{{Select_name}}} {{{Pan_name}}} {{{Zoom_name}}} {{{Rotate_view_name}}}
{{{Shift}}}+ {{{PageUp}}}, {{{PageDown}}} {{{Alt}}}+
{{{Select_text}}} {{{Pan_text}}} {{{Zoom_text}}} {{{Rotate_view_text}}}
{{{Ctrl}}}+{{{Shift}}}+ {{{Shift}}}+
{{{Zoom_alt_text}}} {{{Rotate_view_alt_text}}}

Gesture Navigation (v0.16)

This navigation style was tailored for usability with touchscreen and pen, but is very usable with mouse too.

{{{Select_name}}} {{{Pan_name}}} {{{Zoom_name}}} {{{Rotate_view_name}}} {{{Tilt_view_name}}}
{{{Select_text}}} {{{Pan_text}}} {{{Zoom_text}}} {{{Rotate_view_text}}} {{{Tilt_view_text}}}
{{{Select_gesture_text}}} {{{Pan_gesture_text}}} {{{Zoom_gesture_text}}} {{{Rotate_view_gesture_text}}} {{{Tilt_view_gesture_text}}}

Selecting objects

Simple selection

Objects can be selected by a click with the left mouse button either by clicking on the object in the 3D-view or by selecting it in the tree view.

Preselection

There is also a Preselection mechanism that highlights objects and displays information before selection by just hovering the mouse over the objects. If you don't like this behaviour or you have a slow machine, you can switch preselection off in the preferences.


Manipulating Objects

FreeCAD offers manipulators that are handles that can be used to modify an object's appearance, shape, or other parameters.

Obsolete

The clipping plane is a good example of an object with manipulators. A clipping plane can be activated with the View→Clipping Plane menu. After activation the clipping plane object appears and shows seven obvious manipulators as little boxes: One on each end of its three coordinate axes and one on the center of the plane normal axis. There are four more that are not as obvious: The plane itself and the thin part of the three axis objects.

Scaling
To scale the object click with the left mouse button on the box manipulators at the end of the axes and pull them back and forth. Depending on the object the manipulators work independently or synchronously.
Out of plane shifting
To shift the object along its normal vector, pull the long box on the center of an axis with the left mouse button. For the clipping plane there is only one manipulator along the normal vector.
In plane shifting
To move the center of the clipping plane, click on the plane object and pull it to the desired location.
Rotation
Clicking on the thin part of the axes puts the manipulator in rotation mode.


Hardware support

FreeCAD also supports some 3D input devices.

Mac OS X Issues

Recently we got reports on the forum from Mac users that those mouse button and key combination do not work as expected. Unfortunately, none of the developers owns a Mac, neither do the other regular contributors. We need your help to determine which mouse buttons and key combination work so we can update this wiki.
