Although it is primarily intended for solid bodies, the Std Part can be used to manage any object that has a [[Placement|Placement]] property, so it can also contain [[Mesh_Feature|Mesh Features]], [[Sketch|sketches]], and other objects derived from [[App_GeoFeature|App GeoFeature]]. |

* As an assembly container that groups objects to be manufactured separately then glued or screwed together, like a wooden table. |
|||
* When importing a STEP assembly in FreeCAD, the main assembly and its sub-assemblies are Part containers. |
|||
* A part that is composed of multiple non-fused components, like a ball bearing. |
|||
===Status Active=== |
|||
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. |

[[File:Std Part-tree-active.png|none]] |
|||
===Origini=== |
|||
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. |

===Managementul Vizibilității=== |
|||
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. |

A [[Std_Part|Std Part]] is internally called [[App_Part|App Part]] ({{incode|App::Part}} class), and is derived from an [[App_GeoFeature|App GeoFeature]] ({{incode|App::GeoFeature}} class), therefore it shares most of the latter's properties. |
|||
In addition to the properties described in [[App_GeoFeature|App GeoFeature]], the App Part class has some properties that help it manage information in the context of an assembly, for example, {{PropertyData|Type}}, {{PropertyData|Id}}, {{PropertyData|License}}, {{PropertyData|LicenseURL}}, {{PropertyData|Color}}, and {{PropertyData|Group}}. |

These are the properties available in the [[property editor|property editor]]. Hidden properties can be shown by using the {{MenuCommand|Show all}} command in the context menu of the [[property editor|property editor]]. |

Descriere
Part(piesa) este un container de uz general care ține împreună un grup de obiecte astfel încât ele pot fi mișcate ca o unitate. Piesa poate conține majoritatea obiectelor FreeCAD, cum ar fi corpurile PartDesign, obiecte ale atelierului Part, obiecte Mesh etc.
Piesa oferă un sistem local de coordonate la care se pot atașa schițe și alte obiecte.
Although it is primarily intended for solid bodies, the Std Part can be used to manage any object that has a Placement property, so it can also contain Mesh Features, sketches, and other objects derived from App GeoFeature.
O Piesă se află în bara de instrumente Structure care este afișată în toate atelierele de lucru.
Left: elements inside a Std Part in the tree view. Right: objects positioned in space, referred to the Origin of the Std Part.
Cum se folosește
- Press the Create part 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.
Notes
- As of v0.19, a given object can only belong to a single Part.
- Double-click the Part in the tree view or open the context menu (right-click) and select Toggle active part to activate or deactivate the Part. If another Part is active, it will be deactivated. See active status for more information.
Proprietăți
A Std Part is internally called App Part (App::Part
class), and is derived from an App GeoFeature (App::GeoFeature
class), therefore it shares most of the latter's properties.
In addition to the properties described in App GeoFeature, the App Part class has some properties that help it manage information in the context of an assembly, for example, DateType, DateId, DateLicense, DateLicenseURL, DateColor, and DateGroup.
These are the properties available in the property editor. Hidden properties can be shown by using the Show all command in the context menu of the property editor.
Data
Base
- DateId: ID (Part number) of the item. This field is optional.
- DateLicense: the license under which the part is released.
- DateLicense URL: the Web address where the terms license can be found.
- DatePlacement: specifies the orientation and position of the Part in the 3D space. See Placement.
- DateLabel: the Label is the name given to the operation. This name can be changed at your convenience.
- DateGroup: lists the referenced objects.
Hidden properties Data
- DateMaterial (
Map
): map with material properties. By default, it is empty{}
. - DateMeta (
Map
): map with additional meta information. By default, it is empty{}
. - DateUid (

): the universally unique identifier (UUID) (128-bit number) of the object. This is assigned at creation time. - DateLabel2 (

Bool
): whether to display the object or not. - DateOrigin (

): the App Origin object that is the positional reference for all elements listed in DateGroup. - Date_ Group Touched (

): whether the group is touched or not.

The App Part only has five of the properties of the basic App GeoFeature, and it does not have hidden properties.

Status Active
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.

Managementul Vizibilității
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.

Limite
- Chiar și atunci când o Piesă este activă, obiectele nou create nu sunt lasate în interiorul Piesei/Part, dar vor fi plasate în partea de jos a arborescenței. Pur și simplu glisați și fixați-le peste Piesă.
- O piesă nu are formă. Nu este posibil să aplicați cele mai multe operații 3D asupra unei Piesei, ca operații Booleene.
- În acest moment, Draft Snaps nu funcționează pe unul sau mai multe containere Piesă selectate sau pe obiectele din interiorul unui container.
- Notă a Redactorului: în acest moment nu este clar statutul activ al piesei nu este clar.
Inheritance
A Std Part is formally an instance of the class App::Part
, whose parent is the basic App GeoFeature (App::GeoFeature
class).
Simplified diagram of the relationships between the core objects in the program. The App::Part
class is a simple container that has a position in 3D space, and has an Origin to control the placement of the objects grouped under it.
Scripting
See also: FreeCAD Scripting Basics, and scripted objects.
See Part Feature for the general information on adding objects to the program.
A Std Part (App Part) is created with the addObject()
method of the document. Once a Part exists, other objects can be added to it with the addObject()
or addObjects()
methods of this Part.

doc = App.newDocument()
