Parça , bir grup nesnenin, tek bir birim olarak beraber hareket ettirilebilen, bir çok nesneyi bir arada tutan genel amaçlı konteynerdir. Parça, en çok Parça tasarım gövdeleri, Parça tezgahı nesneleri, Kafes nesneleri, vb. gibi FreeCAD nesnelerini içerebilir.
Parça, eskizlerin ve diğer nesnelerin eklenebileceği yerel bir koordinat sistemi sağlar.
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 the App GeoFeature class.

The Std Part tool is not defined by a particular workbench, but by the base system, thus it is found in the structure toolbar that is available in all workbenches. To group objects arbitrarily without considering their position, use
Std Group; this object does not affect the placements 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.

The Std Part, internally called App Part (App::Part
class), is derived from the App GeoFeature (App::GeoFeature
class) and inherits all its properties. It also has several additional properties. Notably properties that help it manage information in the context of an assembly, for example, VeriType, VeriId, VeriLicense, VeriLicenseURL and VeriGroup.
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.

Bir FreeCAD belgesi birden fazla Parça içerebilir. Bir seferde sadece bir Parça aktif olabilir. Ağaç görünümünde açık mavi bir arka plan rengiyle etkin olan kısım görüntülenecektir.
An open document can contain multiple Parts. But only one Part can be active. The active Part is displayed in the tree view with the background color specified by the Active container value in the preferences editor (by default, light blue). It will also be shown with bold text.
To activate or de-activate a Part:
Document with two Std Parts, of which the second one is active.
Orijin, üç standart eksenden (X, Y, Z) ve üç standart düzlemden (XY, XZ ve YZ) oluşur. Eskizler bu düzlemlere eklenebilir. Parça içindeki tüm unsurlar Parça'nın orijini ile ilişkilendirilir; bu, Parçanın, içerisindeki öğelerin yerleşimini etkilemeden, küresel koordinat sistemine göre hareket ettirilebileceği ve döndürülebileceği anlamına gelir.
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.
Parçanın görünürlüğü, içerdiği herhangi bir nesnenin görünürlüğünün yerini alır. Parça gizlenirse, görünürlüğü true olarak ayarlanmış olsa bile içerdiği nesneler de gizlenir. Bir Parçanın içinde birden fazla nesne bir anda görülebilir.
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 GörünümVisibility property is set to true
. If the Part is visible, then each object's GörünümVisibility 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.

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.
import FreeCAD as App
doc = App.newDocument()
part = App.ActiveDocument.addObject("App::Part", "Part")
obj1 = App.ActiveDocument.addObject("PartDesign::Body", "Body")
obj2 = App.ActiveDocument.addObject("Part::Box", "Box")
part.addObjects([obj1, obj2])
App.ActiveDocument.recompute()
You cannot create a scripted App::Part
. However, you can add App::Part
behavior to a scripted Part::FeaturePython
object by using the following code:
class MyGroup(object):
def __init__(self, obj=None):
self.Object = obj
if obj:
self.attach(obj)
def dumps(self):
return
def loads(self, _state):
return
def attach(self, obj):
obj.addExtension("App::OriginGroupExtensionPython")
obj.Origin = FreeCAD.ActiveDocument.addObject("App::Origin", "Origin")
def onDocumentRestored(self, obj):
self.Object = obj
class ViewProviderMyGroup(object):
def __init__(self, vobj=None):
if vobj:
vobj.Proxy = self
self.attach(vobj)
else:
self.ViewObject = None
def attach(self, vobj):
vobj.addExtension("Gui::ViewProviderOriginGroupExtensionPython")
self.ViewObject = vobj
def dumps(self):
return None
def loads(self, _state):
return None
App.ActiveDocument.addObject("Part::FeaturePython",
"Group",
MyGroup(),
ViewProviderMyGroup(),
True)
