Introducción

La vista 3D de FreeCAD es una instancia de una Coin3D escenografía que forma la ventana más importante de la interfaz. Coin3D es una biblioteca que implementa el estándar de descripción de escenas OpenInventor 2.1.

Certain properties of the view, like background color, mouse navigation style, and zooming steps, can be configured in the preferences editor.

The 3D view is a component of the FreeCAD interface. By default it shows a small widget with coordinate axes, and the navigation cube also with coordinate axes; the grid can be displayed and configured by loading the Draft Workbench.

Acciones

Note: link actions introduced in version 0.19.

Since the tree view lists most objects that are visible in the 3D view, many of the actions are the same to those that can be executed from the tree view.

When the default Start Workbench is active, right clicking on the 3D view shows only one command:

  • Navigation styles: different button styles to use with a 3-button mouse or laptop trackpad.

However, once a Workbench is loaded, there are additional commands:

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:

  • Appearance: launches the dialog to change color and sizes of lines and vertices, and color of faces.
  • Toggle visibility: makes the object visible or invisible in the 3D view.
  • Toggle selectability: makes the object no longer selectable in the 3D view; use again this command to cancel its effect. It sets the object's Selectable attribute to true or false. Change the property by toggling VistaSelectable in the property editor.
  • Go to selection: expand the tree view to show the selected object in the hierarchy.
  • Random color: assigns a random color to the object. It sets the object's ShapeColor attribute to a tuple (r,g,b) with tree random floats between 0 and 1. Change the property by modifying VistaShape Color in the property editor.
  • Delete: removes the object from the document, and from the 3D view, by calling the document's removeObject() method.

Another example, with the Draft Workbench and one object selected, it shows the same commands as with the Part Workbench, but also:

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.
