Std Part/fr

Description
 'Part'  est un conteneur à usage général qui conserve ensemble un groupe d'objets afin qu'ils puissent être déplacés en tant qu'unité. La partie peut contenir la plupart des objets FreeCAD, par exemple des corps PartDesign, des objets de l'atelier Part, des objets de l'atelier Mesh, etc.

La Partie fournit un système de coordonnées local auquel des esquisses et d'autres objets peuvent être attachés.

La Partie se trouve dans la barre d'outils Structure affichée dans tous les ateliers.



Exemples d'utilisation

 * En tant que conteneur d'assemblage qui regroupe des objets à fabriquer séparément puis collés ou vissés, comme une table en bois.
 * Lors de l'importation d'un assemblage STEP dans FreeCAD, l'assemblage principal et ses sous-assemblages sont des conteneurs de pièces.
 * Une pièce composée de plusieurs composants non fusionnés, comme un roulement à billes.

Active Status
A FreeCAD document can contain multiple Parts. Only one Part can be active at a time. An active Part will be displayed in the tree with a light blue background color.

Origin
The Origin consists of the three standard axes (X, Y, Z) and three standard planes (XY, XZ and YZ). Sketches can be attached to these planes. All elements inside the Part are referenced to the Part's Origin; which means that the Part can be moved and rotated in reference to the global coordinate system without affecting the placement of elements inside it.

Visibility Management
The Part's visibility supersedes the visibility of any object it contains. If the Part is hidden, the objects it contains will be hidden as well, even if their visibility is set to true. Multiple objects inside a Part can be visible at a time.

How to use

 * Press the button in the toolbar. The Part automatically becomes active.
 * Double-click the Part in the Model tree to activate or deactivate it.
 * To add objects to a Part, drag & drop them over the Part in the Model tree.
 * To remove objects from a Part, drag & drop them out of the Part and on the document label at the top of the Model tree.

Properties

 * : ID (Part number) of the item. This field is optional.
 * : the license under which the part is released.
 * : the Web address where the terms license can be found.
 * : specifies the orientation and position of the Part in the 3D space. See Placement.
 * : the Label is the name given to the operation. This name can be changed at your convenience.
 * : lists the referenced objects.

Limitations

 * Even when a Part is active, newly created objects are not placed inside the Part, but at the bottom of the tree. Simply drag & drop them over the Part.
 * A Part has no shape. It is therefore not possible to apply most 3D operations on a Part, such as Part Booleans.
 * Redactor's note: at this time, it is unclear whether the Part's active status serves a purpose.
