Interface

Introduction
The FreeCAD interface is based on Qt, a well known graphical user interface toolkit, particularly used in Linux, but also available in Windows and MacOS.



Components of the interface
Like many pieces of software, FreeCAD includes a standard menu bar, and then a series of toolbars and panels where the user tools are found.

The standard menus are:, , , , , ,.

Toolbars
The standard toolbars that appear in the interface are:
 * File toolbar: tools to work with files, open documents, copy, paste, undo and redo actions.
 * Workbench toolbar: tool to select the active workbench.
 * Macro toolbar: tools to record, edit, and execute macros.
 * View toolbar: tools to control how objects appear in the 3D view.
 * Structure toolbar: tools to organize objects in the document, and create links to additional documents.

These can be turned on and off by right clicking on an empty space on one of the toolbars and choosing the desired element, or from the menu,.

Panels
The main panels that allow working with objects are:
 * 3D view: the area where 2D and 3D geometry is drawn.
 * Combo view: the panel that contains the tree view, the task panel, and the property editor.
 * Tree view: the element that shows all objects in the document and their parametric history.
 * Task panel: the panel that shows different actions and options depending on the drawing tool selected.
 * Property editor: the place where object properties are modified.
 * Selection view: the panel that shows elements that are currently selected.
 * Report view: the text box that shows different messages from the application and its tools.
 * Python console: the editor that allows running Python code interactively to see results in the 3D view.
 * Status bar: the bar that shows certain messages from the application, and that has the mouse navigation selector.
 * DAG view: an alternative to the tree view, which shows the relationships between different objects through a graph.

With the exception of the 3D view, all can be turned on and off by right clicking on an empty space on one of the top toolbars and choosing the desired element, or from the menu,.

To activate and deactivate the status bar use the menu,.

Customization
Toolbars can have more or fewer buttons, and custom toolbars can be created with a mix of different tools, and to store developed macros.

These options are in the menu,. See interface customization.
