Preferences Editor/zh-tw

Introduction
To start the Preferences editor select the option from the menu. On the Mac OS the option appears in the  menu instead (this is the default place for preferences on the Mac).

FreeCAD uses a workbench concept, where each workbench is responsible for specific tasks and functions. A workbench can have its own preferences. These will only appear in the Preferences editor if the workbench has been loaded in the current FreeCAD session. See Workbenches below for more information.

If no workbench is loaded, four sections appear in the Preferences editor: General, Display, Workbenches, and Import-Export. Any workbenches that have been loaded, and have their own preferences, will appear below these.

Please note that pressing the button in the lower left corner of the Preferences dialog will reset all FreeCAD preferences to their default values.

Some advanced preferences can only be changed in the Parameter editor. The Fine-tuning page lists some of them.

On the 3D View tab you can specify the following:



導覽
On the Navigation tab you can specify the following:

Workbenches
This preferences section has a single tab: Unloaded Workbenches.

Unloaded Workbenches
To preserve resources, FreeCAD does not automatically load all available workbenches. And only if a workbench has been loaded will its preferences, if any, appear in the Preferences editor.

The Unloaded Workbenches tab displays a list of installed workbenches that have not yet been loaded. To load one or more workbenches select them in the list and then press the button. If a newly loaded workbench has dedicated preference they will appear in a new section in the Preferences editor. Some workbenches add support for additional import and export formats. If there are any related preferences they will appear on one or more new tabs in the Import-Export settings section of the Preferences editor.

For a list of workbench preferences see Workbench preferences



Import-Export settings
The Import-Export settings affect how files are imported and exported. They are described on the Import Export Preferences page.

Scripting
Preferences can be accessed from Python scripts using their corresponding path in the Parameter Editor. For example, the preference appears in  and has type. It can therefore be accessed in Python using the following code:

Finding which parameter is used to store which option from the Preferences editor can require searching a bit, but the Parameter Editor offers a search facility, which should help.

It is likely a bad idea to modify the preferences of other parts of FreeCAD unless doing so at the user's request. The setter can however be used to set parameters for your own workbench, and the getter can be used to obey existing parameters.
