Editor de Preferências
To start the Preferences editor select the Edit → Preferences... option from the menu. On the Mac OS the Preferences... option appears in the FreeCAD 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 thebutton in the lower left corner of the Preferences dialog will reset all FreeCAD preferences to their default values.
This preferences section has 7 tabs: General, Document, Selection, Editor, Output window, Macro, and Units.
On the General tab you can specify the following:
|Alterar idioma||Selection of the language of the FreeCAD user interface|
|Tamanho da lista de arquivos recentes||Specification how many files should be listed in the recent files list|
|Ativar fundo em mosaico||If checked, the background of FreeCAD's main window will by default consist of tiles of this image 64px
This option only has an effect if no Style sheet is selected.
The image can be changed by adding the folders Gui/Images in the folder:
%APPDATA%/FreeCAD (on Windows),
$HOME/.FreeCAD (on Linux) or
$HOME/Library/Preferences/FreeCAD (on MacOS).
Place a file named background.png in the Images folder, and uncheck/check this option to see the changed file.

Common sizes are the powers of two 128, 256, 512.|
|Adicionar o logotipo do programa à miniatura gerada||If checked, the FreeCAD program logo 24px will be added to the thumbnail.|
|Número máximo de arquivos de backup a manter quando salvar novamente o documento||If checked, backup files will be kept when saving the document. You can specify the number of backup files to keep. Backup files are previously saved versions of the document. The first backup file will have the file suffix .FCStd1, the second .FCStd2 and so on.|
|Usar a data e a extensão FCBak||If checked, backup files will get the extension .FCbak and their file names get a date suffix according to the specified date format. For a description of the date format see [https//devhints.io/datetime this site].

|Use OpenGL VBO (Vertex Buffer Object)||If checked, Vertex Buffer Objects (VBO) will be used. A VBO is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the graphics card. VBOs offer substantial performance gains because the data resides in the graphics memory rather than the system memory and so it can be rendered directly by the GPU. For more background info see this webpage.|
|Render Cache introduced in version 0.19||"Render Cache" or "Render Acceleration" is explained in more detail in FreeCAD_assembly3 render-caching. There are 3 options:
|Anti-Aliasing||Selection if and what kind of multisample anti-aliasing is used|
|Transparent objects introduced in version 0.19||Render type of transparent objects. The types are:
|Marker size||Selection of the size of vertices (points) in the Sketcher workbench. The clickable area of points can be additionally enlarged by increasing the Pick radius.|
|Pick radius (px)||Sets the area for picking elements in the 3D view. Larger value makes it easier to pick things, but can make some small features impossible to select.|
|Eye to eye distance for stereo modes||Specification of the eye-to-eye distance used for stereo projections. The specified value is a factor that will be multiplied with the bounding box size of the 3D object that is currently displayed.|
|Backlight color||If checked, backlight is enabled with the defined color. Backlight is used for rendering back sides of faces. Usually, you don't see them in solids, unless you slice one with a clipping plane, or if the faces aren't oriented correctly. It is only active for objects whose Lighting property (on the View tab) is set to One side. If disabled, back sides of faces of objects in One side lighting mode will be black.
The related Intensity setting specifies the intensity of the backlight.
|Camera type||Selection of the camera projection type.|
On the Navigation tab you can specify the following:
|Navigation cube||If checked, the Navigation cube will always be shown.
Steps by turn defines the number of steps required for a full rotation when using the Navigation cube rotation arrows.
Corner defines where the Navigation cube is displayed on the screen when creating or opening a document.
If Rotate to nearest is checked, the 3D view is rotated to the nearest most logical state when a cube face is clicked. When it is off, clicking to a cube face will and up always to the same position, no matter in what cube state you were when you clicked the face. introduced in version 0.20
Cube size defines the size of the cube. introduced in version 0.20
|3D Navigation||Selection of a navigation settings set. To see what each set defines, select it and then press the button.|
|Orbit style||Selection of the rotation orbit style. When viewing a part in the x-y plane and being in the rotation mode of the 3D navigation, the difference is: If Trackball is selected, moving the mouse horizontally will rotate the part around the y-axis, if Turntable is selected the part will be rotated around the z-axis.|
|Rotation mode||Defines the rotation center. Select Window center, Drag at cursor, or Object center.|
|Default camera orientation||Selection of the camera orientation for new documents. This setting is also used by the Std ViewHome command.|
|New document scale||Affects the initial camera zoom level for new documents. The value you set is the diameter of a sphere that fits in 3D view. Default is 100 mm. It also sets the initial size of origin features (base planes in new PartDesign Bodies).|
|Enable animation||If checked, rotations can be animated. If for example the 3D Navigation set CAD is used and the mouse is moved while the scroll wheel and the right mouse button are pressed, parts are rotated. If one keeps the mouse moving while releasing e.g. the right mouse button, the rotation will continue as animation. To end the animation left-click with the mouse.|
|Zoom at cursor||If checked, zoom operations will be performed at the position of the mouse pointer. Otherwise zoom operations will be performed at the center of the current view. The Zoom step defines how much will be zoomed. A zoom step of 1 means a factor of 7.5 for every zoom step.|
|Invert zoom||If checked, the direction of zoom operations will be inverted|
|Disable touchscreen tilt gesture||If checked, the tilting gesture will be disabled for pinch-zooming (two-finger zooming). This only affects the 3D Navigation set Gesture.|
On the Colors tab you can specify the following:
|Enable preselection highlighting||If checked, preselection is turned on and the specified color will be used for it. Preselection means that for example edges in parts will be highlighted while hovering over them with the mouse to indicate they can be selected.|
|Enable selection highlighting||If checked, selection highlighting is turned on and the specified color will be used for it|
|Simple color||If selected, the background of the 3D view will have the selected color|
|Color gradient||If selected, the background of the 3D view will have a vertical color gradient. The first color is the color at the top of the 3D view, the second the color at the bottom.|
|Middle color||Is only enabled if Color gradient is selected. If checked, the color gradient will get the selected color as the middle color.|
|Object being edited||Selection of the background color for objects in the tree view that are currently edited|
|Active container||Selection of the background color for active containers in the tree view. For example an active PartDesign Body will get the selected background color.|
Vista de malhas
This tab is only available if the Mesh Workbench has been loaded.
On the Mesh view tab you can specify the following:
|Default mesh color||Selection of the default shape color|
|Default line color||Selection of the default line color|
|Mesh transparency||Specification of the default mesh transparency|
|Line transparency||Specification of the default line transparency|
|Two-side rendering||If checked, the color of the interior side of faces will be the same as the exterior side. If not checked either the backlight color, if enabled, or black will be used instead.|
|Show bounding-box for highlighted or selected meshes||If checked, a yellow bounding box will be displayed for highlighted or selected meshes|
|Define normal per vertex||If checked, Phong shading is used, otherwise flat shading. Shading defines the appearance of surfaces. With flat shading the surface normals are not defined per vertex. This leads to an unrealistic appearance for curved surfaces. While Phong shading leads to a more realistic, smoother appearance.|
|Crease angle||The crease angle is a threshold angle between two faces. It can only be set if the option Define normal per vertex is used.
Bancadas de trabalho
This preferences section has a single tab: Available Workbenches.
Bancadas de trabalho descarregadas
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 thebutton.
In FreeCAD version 0.20 the Available Workbenches tab displays a list of all installed workbenches. To load a workbench press itsbutton. If you check a workbench's Autoload 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 settings section of the Preferences editor.
For a list of workbench preferences see Workbench preferences
The Import-Export settings affect how files are imported and exported. They are described on the Import Export Preferences page.
