3D view/pt-br

Introdução
A vista 3D,que constitui a janela mais importante da  interface do FreeCAD, é uma instância da Coin3D, biblioteca para implementação de área de modelagem que segue o padrão OpenInventor 2.1  scenegraph

Certas propriedades da visualização, como cor de fundo, estilo de navegação do mouse, e tarefas como fazer um zoom, podem ser configuradas no  editor de preferências.



Ações
links para as ações da.

Uma vez que a vista hierárquica de objetos lista a maioria dos objetos que estão visíveis na área de modelagem 3D, é possível realizar, direto nesta área, muitas ações que normalmente são executadas pela  vista hierárquica de objetos.

When the default Start Workbench is active, right clicking on the 3D view shows only one command:
 * : different button styles to use with a 3-button mouse or laptop trackpad.

However, once a Workbench is loaded, there are additional commands:
 * : Make Link.
 * : Simple group, Group with links, Group with transform links.
 * : pans and zooms the view to fit all objects in the document on the screen.
 * : pans and zooms the view to tightly fit the currently selected object on the screen.
 * : as is, flat lines, shaded, wireframe, points, hidden line, no shading.
 * : isometric, front, top, right, rear, bottom, left, rotate left, rotate right.
 * : toggle measurement, clear measurement.
 * : docked, undocked, and fullscreen.

Additionally, depending on the workbench and object that is active, other contextual commands may become available.

For example, with the Part Workbench and one object selected:
 * : launches the dialog to change color and sizes of lines and vertices, and color of faces.
 * : makes the object visible or invisible in the 3D view.
 * : makes the object no longer selectable in the 3D view; use again this command to cancel its effect. It sets the object's attribute to  or . Change the property by toggling  in the property editor.
 * : expand the tree view to show the selected object in the hierarchy.
 * : assigns a random color to the object. It sets the object's attribute to a tuple  with tree random floats between 0 and 1. Change the property by modifying  in the property editor.
 * : removes the object from the document, and from the 3D view, by calling the document's method.

Another example, with the Draft Workbench and one object selected, it shows the same commands as with the Part Workbench, but also:
 * : object creation and modification commands from the Draft Workbench.
 * : additional contextual commands provided by the Draft Workbench.

Detalhes
FreeCAD uses the Quarter library to use Coin3D in a Qt environment.

It is possible to interact directly with the 3D view scenegraph from the Python console by using the Python library Pivy.

 * Pivy, usage of Coin3D from the Python console.
 * Third party libraries used by FreeCAD.
