Preferences Editor

Introduction
The preferences system of FreeCAD is located in the. On the Mac OS the menu option appears in the FreeCAD menu instead of the Edit menu (this is the default place for preferences on the Mac).

FreeCAD functionality is divided into different modules, each module being responsible for the working of a specific workbench. FreeCAD also uses a concept called "late loading", which means that components are loaded only when they are needed. You may have noticed that when you select a workbench on the FreeCAD toolbar, that workbench and all its components get loaded at that moment. This includes its preferences settings.

Without any module loaded, you will have access to two configuration sections, responsible for the general application settings and for the display settings. When you are in a certain workbench the preferences of this workbench will appear as new section and file formats supported by the workbench will appear as new tab in the section.

Clicking the button in the lower left corner of any preferences display will set all of the FreeCAD preferences to their default values.
