==Description==
==Descripción==


<div class="mw-translate-fuzzy">
'''Part''' is a general purpose container that keeps together a group of objects so that they can be moved as a unit. Part can contain most if not any FreeCAD object such as PartDesign Bodies, Part workbench objects, Mesh objects, etc.
'''Parte''' es un contenedor de propósito general que mantiene juntos un grupo de objetos para que puedan moverse como una unidad. La parte puede contener la mayoría de los objetos de FreeCAD, como conjuntos de PartDesign, objetos del ambiente de trabajo de Pieza, objetos de malla, etc.
</div>


<div class="mw-translate-fuzzy">
Part provides a local coordinate system to which sketches and other objects can be attached.
Part proporciona un sistema de coordenadas local al que se pueden adjuntar sketches y otros objetos.
</div>


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]].
Part is found in the Structure toolbar that is displayed in all workbenches.


<div class="mw-translate-fuzzy">
{{Version|0.17}}
Part se encuentra en la barra de herramientas Estructura que se muestra en todos los ambientes de trabajo.

</div>
===Example uses===
* 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.


To group objects in general use [[Std_Group|Std Group]]. This object does not affect the positions of the elements that it contains; it is essentially just a folder that is used to keep the [[tree_view|tree view]] organized.
===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.
[[File:Std Part-tree-active.png|none]]
===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.
[[File:PartDesign_Body_tree-02.png|none]]
===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.


[[File:Std Part-tree.png]][[File:Std Part example.png]]
==How to use==


{{Caption|Left: elements inside a Std Part in the [[tree_view|tree view]]. Right: objects positioned in space, referred to the Origin of the Std Part.}}
* Press the {{KEY|[[Image:Std Part.png|24px]] '''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.


<div class="mw-translate-fuzzy">

==Propiedades==

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]].

The Std Part is intended to be the basic building block to create assemblies. Unlike a [[PartDesign_Body|PartDesign Body]], an assembly is meant to be a collection of separate, distinguishable elements which are connected in some way in the physical world, for example, through pressure, screws, or glue.

Examples that could be Parts:
* A wooden table that consists of individual wooden pieces (legs, top), which are put together by glue or metal screws.
* A ball bearing that is composed of multiple steel balls, an inner ring, a retainer, a seal, and an outer ring.
* An assembly of a screw with a washer, and a matching nut.

An open document can contain multiple Parts. An active Part will be displayed in the [[tree view|tree view]] with the background color specified by the {{MenuCommand|Active container}} value in the [[Preferences_Editor#Colors|preferences editor]] (by default, light blue). An active part will also be shown in bold text.

Descripción

Parte es un contenedor de propósito general que mantiene juntos un grupo de objetos para que puedan moverse como una unidad. La parte puede contener la mayoría de los objetos de FreeCAD, como conjuntos de PartDesign, objetos del ambiente de trabajo de Pieza, objetos de malla, etc.

Part proporciona un sistema de coordenadas local al que se pueden adjuntar sketches y otros objetos.

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.

Part se encuentra en la barra de herramientas Estructura que se muestra en todos los ambientes de trabajo.

To group objects in general use Std Group. This object does not affect the positions of the elements that it contains; it is essentially just a folder that is used to keep the tree view organized.

Left: elements inside a Std Part in the tree view. Right: objects positioned in space, referred to the Origin of the Std Part.

Como utilizar

  • Presione el botón Create part en la barra de herramientas. La Part se activa automáticamente.
  • Haga doble clic en la Part en el árbol del Modelo para activarlo o desactivarlo.
  • Para agregar objetos a una Part, arrástrelos y suéltelos sobre la Part en el árbol del Modelo.
  • Para eliminar objetos de una Part, arrástrelos y suéltelos de la Part y en la etiqueta del documento en la parte superior del árbol del modelo.

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.

Limitaciones

  • Incluso cuando una Part está activa, los objetos recién creados no se colocan dentro de la Part, sino en la parte inferior del árbol. Simplemente arrástrelos y suéltelos sobre la Part.
  • Una part no tiene forma. Por lo tanto, no es posible aplicar la mayoría de las operaciones 3D en una Part, como Part Booleans.
  • En este momento, Draft Snap no funciona en contenedores de Part seleccionados o en objetos dentro de un contenedor de Part.
  • Nota del Redactor: en este momento, no está claro si el estado activo de la Part cumple un propósito .

Propiedades

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, DatosType, DatosId, DatosLicense, DatosLicenseURL, DatosColor, and DatosGroup.

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

  • Datos Id: ID (Número de pieza) del artículo. Este campo es opcional.
  • Datos License: la licencia bajo la cual se lanza la Part.
  • Datos License URL: la dirección web donde se pueden encontrar los términos de licencia.
  • Datos Placement: especifica la orientación y la posición de la Part en el espacio 3D. Ver Placement.
  • Datos Label: la label/etiqueta es el nombre dado a la operación. Este nombre se puede cambiar a su conveniencia.
  • Datos Group: enumera los objetos a los que se hace referencia.

Hidden properties Data

  • DatosMaterial (Map): map with material properties. By default, it is empty {}.
  • DatosMeta (Map): map with additional meta information. By default, it is empty {}.
  • DatosUid (UUID): the universally unique identifier (UUID) (128-bit number) of the object. This is assigned at creation time.
  • DatosLabel2 (String): a longer, user editable description of this object, it is an arbitrary UTF8 string that may include newlines. By default, it is an empty string "".
  • DatosExpression Engine (ExpressionEngine): a list of expressions. By default, it is empty [].
  • DatosVisibility (Bool): whether to display the object or not.
  • DatosOrigin (Link): the App Origin object that is the positional reference for all elements listed in DatosGroup.
  • Datos_ Group Touched (Bool): whether the group is touched or not.

View

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

Base

  • VistaDisplay Mode (Enumeration): Group.
  • VistaOn Top When Selected (Enumeration): Disabled (default), Enabled, Object, Element.
  • VistaSelection Style (Enumeration): Shape (default), BoundBox. If the option is Shape, the entire shape (vertices, edges, and faces) will be highlighted in the 3D view; if it is BoundBox only the bounding box will be highlighted.
  • VistaShow In Tree (Bool): if it is true, the object appears in the tree view. Otherwise, it is set as invisible.
  • VistaVisibility (Bool): if it is true, the object appears in the 3D view; otherwise it is invisible. By default this property can be toggled on and off by pressing the Space bar in the keyboard.

Ejemplos de uso

  • Como un contenedor de ensamblaje que agrupa los objetos que se fabricarán por separado, luego se pegarán o atornillarán, como una mesa de madera.
  • Al importar un STEP ensamblado en FreeCAD, el ensamblaje principal y sus subconjuntos son contenedores Part.
  • Una Part que se compone de múltiples componentes no fusionados, como un cojinete de bolas.

The Std Part is intended to be the basic building block to create assemblies. Unlike a PartDesign Body, an assembly is meant to be a collection of separate, distinguishable elements which are connected in some way in the physical world, for example, through pressure, screws, or glue.

Examples that could be Parts:

  • A wooden table that consists of individual wooden pieces (legs, top), which are put together by glue or metal screws.
  • A ball bearing that is composed of multiple steel balls, an inner ring, a retainer, a seal, and an outer ring.
  • An assembly of a screw with a washer, and a matching nut.

Left: three individual contiguous solids, each of them modelled by a PartDesign Body. Right: the individual Bodies put together inside a Std Part to create an assembly.

In general terms, when importing a STEP file into the program, the main assembly and its sub-assemblies will be imported as Part containers, each of them containing a simple Part Feature.

Detailed explanation

Estado activo

Un documento de FreeCAD puede contener varias Part. Solo una Part puede estar activa a la vez. Una Part activa se mostrará en el árbol con un color de fondo azul claro.

An open document can contain multiple Parts. An active Part will be displayed in the tree view with the background color specified by the Active container value in the preferences editor (by default, light blue). An active part will also be shown in bold text.

To activate or de-activate a Part:

  • Double click on it on the tree view, or
  • Open the context menu (right click) and select Toggle active part.

Notes:

  • The active status of Parts was developed in v0.17 in parallel with the active status of PartDesign Bodies; however, as of v0.19 this status does not serve a real purpose for Parts.
  • Even when a Part is active, newly created objects are not placed inside of it automatically. In this case, simply drag these new objects, and drop them onto the desired Part.
  • Only a single Part can be active at a time.

Document with two Std Parts, of which the second one is active.

Origen

The Origin consta de los tres ejes estándar (X, Y, Z) y tres planos estándar (XY, XZ y YZ). Sketches se pueden unir a estos planos. Todos los elementos dentro de la Part están referenciados al Origen de la Part; lo que significa que la Part se puede mover y rotar en referencia al sistema de coordenadas global sin afectar la ubicación de los elementos en su interior.

The Origin consists of the three standard axes (X, Y, Z) and three standard planes (XY, XZ and YZ). Sketches and other objects can be attached to these elements when creating them.

Left: Part Origin in the tree view. Right: representation of the Origin elements in the 3D view.

Note: the Origin is an App Origin object (App::Origin class), while the axes and planes are objects of type App::Line and App::Plane respectively. Each of these elements can be hidden and unhidden individually with the Space bar; this is useful to choose the correct reference when creating other objects.

Note 2: 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 the elements inside.

Gestión de visibilidad

La visibilidad de la Part reemplaza la visibilidad de cualquier objeto que contenga. Si la Part está oculta, los objetos que contiene también estarán ocultos, incluso si su visibilidad está establecida en verdadero. Múltiples objetos dentro de una Part pueden ser visibles a la vez.

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 individual VistaVisibility property is set to true. If the Part is visible, then each object's VistaVisibility determines whether the object is shown or not.

The visibility of the Std Part determines whether the objects grouped under it are shown in the 3D view or not. Left: the Part is hidden, so none of the objects will be shown in the 3D view. Right: the Part is visible, so each object controls its own visibility.

Inheritance

A Std Part is formally an instance of the class App::Part, whose parent is the basic App GeoFeature (App::GeoFeature class), and is augmented with an Origin extension.

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 document.

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.

import FreeCAD as App

doc = App.newDocument()
obj = App.ActiveDocument.addObject("App::Part", "Part")

bod1 = App.ActiveDocument.addObject("PartDesign::Body", "Body")
bod2 = App.ActiveDocument.addObject("Part::Box", "Box")

obj.addObjects([bod1, bod2])
App.ActiveDocument.recompute()
