FreeCAD的首选项系统位于Edit menu → Preferences。
FreeCAD中的功能被分为不同的模块,每个模块负责实现一种特定workbench的具体工作。 FreeCAD采用的是延迟加载方式,意即只有当需要使用特定组件时才会进行加载。您在FreeCAD的工具栏中选择工作台时可能会注意到这一点,因为在加载工作台及其所有组件时需要花费一点儿时间。在进行首选项设置时也是如此。
To preserve resources, FreeCAD does not automatically load all available workbenches. See Workbenches for more information. For a list of workbench related preferences see Workbench related preferences.
在没有加载任何模块时,您可以访问两个配置部分,分别用于应用通用设置(general)与显示设置(display)。当您使用特定的工作台时,便会在新选项卡中显示对应工作台的首选项设置,并在Import-Export新加部分显示该工作台所支持的文件格式。
点击首选项左下角的Reset按钮,即可将FreeCAD中的所有首选项设置还原为其默认值。
Some advanced preferences can only be changed in the Parameter editor. The Fine-tuning page lists some of them.
This page has been updated for version 1.0.
本首选项部分包含6个选项卡:

This preferences group has six standard pages: 3D View, Light Sources, UI, Navigation, Colors and Advanced. A seventh page, Mesh view, is added if the Mesh Workbench has been loaded.
On this page you can specify the following:
Name | Description |
---|---|
Show coordinate system in the corner | If checked, the main coordinate system will be shown in the lower right corner of the 3D view.
The Relative size defines the size of the representation as a percentage of the view size (the minimum of its height and width). The Letter color defines the color of the axis letters. introduced in 1.1: The X-axis color, Y-axis color and Z-axis color define the colors of the axes. |
Show axis cross by default | If checked, the axis cross will be shown by default in the 3D view. |
Show counter of frames per second | If checked, the time needed for the last operation and the resulting frame rate will be shown in the lower left corner of the 3D view. |

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 Understanding OpenGL Objects. |
Render Cache | "Render Cache" or "Render Acceleration" is explained in more detail in FreeCAD assembly3 render-caching. The options are:
|
Anti-Aliasing | Specifies if and what type of multisample anti-aliasing is used |
Transparent objects | Specifies the render type of transparent objects. The options are:
|
Marker size | Specifies the size of vertices (points) in the Sketcher Workbench. The clickable area of points can be additionally enlarged by increasing the Pick radius. |
Eye to eye distance for stereo modes | Specifies 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 the 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 used for objects whose Lighting property (on the View tab) is set to One side. If disabled, the back side of the faces of those objects will be black.
The related Intensity setting specifies the intensity of the backlight. |
Camera type | Specifies the camera projection type. The options are:
|
On this page you can specify the following:
Name | Description |
---|---|
Light source | If checked, the objects in the 3D view are lit by a directional light source and the specified color will be used for it. Without this all objects appear as solid black. |
Intensity | Move the slider to change the intensity of the light. |
Direction | The preview shows the XY plane and a sphere, indicating the light source, connected by a line to a cone, indicating the direction. All elements in the preview, the sphere, the small cone directly attached to it, the line and the large cone, can be dragged to change the direction of the light. For more precision the direction vector can be set by specifying the x, y and z values or the q0 - q3 quaternion values. You can zoom the preview in and out with the buttons in the lower left corner. |
On this page you can specify the following:
Name | Description |
---|---|
Navigation cube | If checked, the Navigation cube is shown in the 3D view.
Steps by turn defines the number of steps required for a full rotation when using the Navigation cube rotation arrows. If Rotate to nearest is checked, the 3D view is rotated to the nearest most logical position, based on the current orientation of the cube, when a cube face is clicked. Else clicking a face will always result in the same rotation. Cube size defines the size of the cube. Color sets the base color for all elements. introduced in 0.21 Corner defines where the Navigation cube is displayed in the 3D view. The options are:
Font name specifies the font used for the cube's texts. introduced in 0.21 Opacity when inactive Opacity of the Navigation cube when not hovered by the mouse. introduced in 1.0 |
Rotation center indicator introduced in 1.0 | If checked, the rotation center of the view is shown when dragging.
The Sphere size and the Color and transparency of the indicator can be specified. |
3D Navigation | Specifies a mouse navigation style. To see the details of each style, select it and then press the Mouse... button. |
Orbit style | Specifies the rotation orbit style used when in rotation mode. The options are:
|
Rotation mode | Defines the rotation center. The options are:
|
Default camera orientation | Specifies the camera orientation for new documents. This setting is also used by the Std ViewHome command. |
Camera zoom | Affects the initial camera zoom level for new documents. The value you set is the diameter of a sphere that fits in the 3D view. The default is 100 mm. It also sets the initial size of origin features (base planes in new PartDesign Bodies and Std Parts). |
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, and 3D Navigation is set to Gesture, the tilting gesture will be disabled for pinch-zooming (two-finger zooming). |
Enable support of legacy space mouse devices introduced in 1.1 | If checked, legacy space mouse devices can be used. May be backported to version 1.0.1. |
Animations | If checked, view rotations and zooms, except those invoked by mouse actions, are animated. The Animation duration can be specified.
Enable spinning animations if checked, and if 3D Navigation is set to CAD, rotations invoked by the mouse can be animated as well. If the mouse is moved while the scroll wheel and the right mouse button are pressed, the view is rotated. If one keeps the mouse moving while releasing the right mouse button, the rotation will continue. To end this animation left-click with the mouse. |
On this page you can specify the following:
Name | Description |
---|---|
Simple color | If selected, the background of the 3D view will have the specified color. |

Radial gradient introduced in 0.21 | If selected, the background of the 3D view will have a radial color gradient defined by the specified Central and End colors. if enabled, a Midway color can also be specified. Press the |
Object being edited | Specifies the background color for objects in the tree view that are currently edited. |
Active container | Specifies the background color for active containers in the tree view. For example an active PartDesign Body will get this color. |
Label text color | The color used for the labels of the color bar. The color bar is used in the Mesh Workbench and FEM Workbench. |
Label text size | The size of those labels. |
This page is only available if the Mesh Workbench has been loaded.
On this page you can specify the following:
Name | Description |
---|---|
Default mesh color | Specifies the default face color. |
Default line color | Specifies the default line color. |
Mesh transparency | Specifies the default mesh transparency. |
Line transparency | Specifies the default line transparency. |
Two-side rendering | If checked, the default value for the 视图Lighting property is Two side instead of One side . Two side means the color of the interior side of faces is the same as the color of the exterior side. One side means their color is either the backlight color, if enabled, or black.
|
Show bounding-box for highlighted or selected meshes | If checked, the default value for the 视图Selection Style property is BoundBox instead of Shape . BoundBox means a highlighted bounding box is displayed if meshes are highlighted or selected. Shape means the shape itself is then highlighted.
|
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.
