Общ преглед

Методите са избиране във FreeCAD позволяват избиране на обекти в интерфейса на FreeCAD: като 3D Изглед, Дарвовидния изглед, selection view и други диалогови прозорци. Някои методи за подбор са специфични за работната маса и са документирани в конкретната документация на работната маса.

3D Изглед

В 3D изглед има различни начини за избор на обекти.

Просто избиране

Прост избор с мишката (по подразбиране с ляво щракване) и предварителен избор (при задържане на курсора) са описани в страница Навигация с мишката.

Повтарящи се кликвания

Първото щракване избира под-елемент (връх, ръб или лице) на обекта под курсора на мишката. Второто щракване избира целия обект.

Третото щракване разширява селекцията до своя контейнерен обект (PartDesign Body, Std Part и други). Допълнителни кликвания разширяват селекцията нагоре по веригата контейнери.

Команди за избиране

Selection view

The selection view shows the names of the objects being selected, including their full name within an object, for example, Unnamed#Body.Box001.Face17.

It also allows to perform some actions like Std ViewFitSelection, and sending the object to the Python console.

Object export

This should be in the selection view page.

Select any complex object, for example, a PartDesign Body or Std Part, then in the selection view select again the object, and then press Ctrl + C in the keyboard to open the Object selection dialog. This allows copying the selected object together with all or only some of that object's dependency objects. For example, for a Std Part the possible objects to select include the Std Part itself, but also its Origin, its three base axes (XYZ), and its three base planes (XY, YZ, XZ).

After pressing OK, the selected objects are copied into memory, and then can be pasted in the document to duplicate these objects only.

Object selection dialog that is launched from the selection view.

Tree view

In the tree view items can be selected, or deselected, one at a time, by holding the Ctrl key and clicking with the mouse.

A range of items can be selected by clicking on the first item, holding Shift, and clicking on the last item.

Selecting a single item will also show its properties in the property editor.

Double clicking will open any associated task panel containing actions. Make sure to close this task panel before executing another command or switching to any other workbench.

More methods are available by opening the context menu (right-click), depending on the object selected or the active workbench; see the information in tree view.

Scripting

Selecting objects is inherently a graphical task and therefore it is only available when the graphical user interface is loaded.

These methods can be used in macros or from the Python console: 

import FreeCADGui as Gui

Gui.Selection.addSelection
Gui.Selection.addSelectionGate
Gui.Selection.Filter

The addSelectionGate method prevents the user from selecting objects not specified in the selection string. A symbol appears when the pointer is over an item not in the specified group. 

Gui.Selection.addSelectionGate("SELECT Part::Feature SUBELEMENT Edge")

#### or
Gui.Selection.addSelectionGate("SELECT Part::Feature SUBELEMENT Face")

#### or
Gui.Selection.addSelectionGate("SELECT Part::Feature SUBELEMENT Vertex")

To remove SelectionGate(): 

Gui.Selection.removeSelectionGate()

See the Source documentation and Std PythonHelp for more help on using these tools.
