Selection methods/ru

Overview
Selection methods in FreeCAD allow picking objects in the FreeCAD Interface: such as 3D view, tree view, selection view, and other dialogs. Some selection methods are workbench specific and are documented in the particular workbench documentation.

Трёхмерный вид
In the 3D view there are various ways of selecting objects using the mouse pointer.

Простое выделение
Simple selection with the mouse (by default left-click) and pre-selection (hover) are described in the mouse navigation page.

Повторные клики
The first click selects a sub-element (vertex, edge or face) of the object under the mouse. A second click selects the whole object.

The third click extends the selection to its container object (PartDesign Body, Std Part, and others). Further clicks expand the selection up the container chain.

Команды выделения
Mouse drag selection to select multiple objects or sub-elements (vertices or faces) is available using Std SelectAll, Std BoxSelection, Part BoxSelection, and Std BoxElementSelection.

The Box selection modes revert to the default Std SelectAll, after any selection. (What does this mean??)

Панель выделения
The selection view shows the names of the objects being selected, including their full name within an object, for example,.

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

Экспорт объектов
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 +  in the keyboard to open the  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, the selected objects are copied into memory, and then can be pasted in the document to duplicate these objects only.



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

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

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

These commands can be used in macros or from the Python console.

The command restricts 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.

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