Preferences Editor/hr

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, five sections appear in the Preferences editor: General, Display, Workbenches, Addon Manager 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.

This preferences section has 9 standard tabs: General, Document, Selection, Cache, Editor, Python console, Output window, Macro and Units. A 10th tab, Help, is added if the Help Addon is available. This addon can be installed via the Addon Manager.

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

Available 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.

In FreeCAD version 0.19 the tab has a different label: Unloaded Workbenches, and the 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.

In FreeCAD version 0.20 the Available Workbenches tab displays a list of all installed workbenches. To load a workbench press its button. If you check a workbench's checkbox it will autoload when FreeCAD starts up. Loading more workbenches will make the startup slower, but switching between workbenches that have already been loaded is faster.

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 section of the Preferences editor.
