FreeCAD 的功能被分为了不同的模块,每个模块负责某个具体[[Workbenches/zh|工作台]]的相关工作。FreeCAD 还使用了一种称之为后加载的观念,意即相关组件只有在需要时才被加载进来。或许你已经注意到,当你在 FreeCAD 工具栏中选择一个工作台时,此工作台和它的所有组件都同时被加载进来。这其中包含了它的首选项设置。

==Import-Export settings==


===Mesh view===
The Import-Export settings affect how files are imported and exported to and from FreeCAD. Note that the Import-Export preferences dialog offers file type settings for most workbenches but not every workbench is able to import/export all file types.


This tab is only available if the [[Mesh_Workbench|Mesh Workbench]] has been loaded.
FreeCAD supports many file formats. For the following file formats it offers to apply special settings:


On the ''Mesh view'' tab you can specify the following:
===DAE===

The [http://en.wikipedia.org/wiki/COLLADA Collada] DAE (Digital Asset Exchange) format is a standard file format for exchange of Mesh data. The [[Arch Module|Arch workbench]] can import meshes from {{FileName|.dae}} files, and export Arch and other [[Part Module|Shape]]-based objects to the {{FileName|.dae}} format. The Collada import functionality in the Arch module depends on [http://pycollada.github.io/ pycollada]. If it is not installed on your system, Collada import/export will be disabled.

For the DAE format you can specify the following:

|-
| {{MenuCommand|Scaling factor}}
| {{MenuCommand|Default mesh color}}
| Specifies the default face color.
| All dimensions in the file will be scaled with the specified factor
|-
|-
| {{MenuCommand|Mesher}}
| {{MenuCommand|Default line color}}
| Specifies the default line color.
| Sets the meshing program that should be used. If using ''Netgen'', make sure that it is available. This can be checked by using the [[Mesh_Workbench|Mesh module]] and [[Mesh_MeshFromShape|creating a mesh]] using Netgen. If it is not available another version of FreeCAD, compiled with Netgen, must be installed.
|-
|-
| {{MenuCommand|Tessellation}}
| {{MenuCommand|Mesh transparency}}
| Specifies the default mesh transparency.
| The tessellation value to use with the ''Builtin'' and the ''Mefisto'' meshing program.
|-
|-
| {{MenuCommand|Grading}}
| {{MenuCommand|Line transparency}}
| Specifies the default line transparency.
| The grading value to use for meshing using ''Netgen''. This value describes how fast the mesh size decreases. The gradient of the local mesh size h(x) is bounded by &<nowiki />#124;Δh(x)&<nowiki />#124; ≤ 1/''value''.
|-
|-
| {{MenuCommand|Segments per edge}}
| {{MenuCommand|Two-side rendering}}
| If checked, the default value for the {{PropertyView|Lighting}} property is {{value|Two side}} instead of {{value|One side}}. {{value|Two side}} means the color of the interior side of faces is the same as the color of the exterior side. {{value|One side}} means their color is either the [[#3D_View|backlight color]], if enabled, or black.
| The maximum number of segments per edge
|-
|-
| {{MenuCommand|Segments per radius}}
| {{MenuCommand|Show bounding-box for highlighted or selected meshes}}
| If checked, the default value for the {{PropertyView|Selection Style}} property is {{value|BoundBox}} instead of {{value|Shape}}. {{value|BoundBox}} means a highlighted bounding box is displayed if meshes are highlighted or selected. {{value|Shape}} means the shape itself is then highlighted.
| The number of segments per radius
|-
|-
| {{MenuCommand|Second order}}
| {{MenuCommand|Define normal per vertex}}
| If checked, [https://en.wikipedia.org/wiki/Phong_shading 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.
| Allow a second order mesh
|-
|-
| {{MenuCommand|Optimize}}
| {{MenuCommand|Crease angle}}
| The crease angle is a threshold angle between two faces. It can only be set if the option {{MenuCommand|Define normal per vertex}} is used.

===DWG===


==Workbenches==
DWG (from drawing) is a proprietary binary file format used for storing two- and three- dimensional design data and metadata. Since it is a closed source file format it cannot be directly supported by FreeCAD. Therefore the external file converter [[FreeCAD and DWG Import|ODA is required]].


This preferences section has a single tab: Available Workbenches.
For the DWG format you can only specify the path to ODA. '''note:''' All settings for DXF file format also apply to DWG.

===Available Workbenches===

These preferences control workbench loading.

| If checked, the Python importer is used, otherwise the newer C++ one. The C++ importer is faster, but has not as many features yet.
|-
| {{MenuCommand|Allow FreeCAD to automatically download and update the DXF libraries}}
| By checking this, you will allow FreeCAD to download the [https://github.com/yorikvanhavre/Draft-dxf-importer Python converter] for DXF import and export. This converter cannot be bundled with FreeCAD because it has a different software license.
|-
| {{MenuCommand|Import}}
| Select what will be imported.<br/>If '''texts and dimensions''' is unchecked, texts and [https://www.autodesk.com/techpubs/autocad/acad2000/dxf/mtext_dxf_06.htm mtexts] won't be imported.<br/>If '''layouts''' is checked, paper space objects will be imported too.<br/>Check '''*blocks''' if you want the non-named blocks (beginning with a *) to be imported too.
|-
| {{MenuCommand|Create}}
| Select what will be created.<br/>If '''simple Part shapes''' is selected, only standard Part objects will be created. This is the fastest.<br/>If '''Draft objects''' is selected, parametric Draft objects will be created whenever possible.<br/>If '''Sketches''' is selected, sketches will be created whenever possible.
|-
| {{MenuCommand|Scale factor to apply to imported files}}
| Scale factor to apply to DXF files on import. The factor is the conversion between the unit of your DXF file and millimeters. Example: for files in millimeters: 1, in centimeters: 10, in meters: 1000, in inches: 25.4, in feet: 304.8
|-
| {{MenuCommand|Get original colors from the DXF file}}
| If checked, colors will be retrieved from the DXF objects whenever possible. Otherwise default colors will be applied.
|-
| {{MenuCommand|Join geometry}}
| If checked, FreeCAD will try to join coincident objects into wires. Note that this can take a while.
|-
| {{MenuCommand|Group layers into blocks}}
| If checked, objects from the same layers will be joined into Draft Blocks, turning the display faster, but making them less easily editable ??The Draft Wiki pages don't mention Draft blocks??
|-
| {{MenuCommand|Use standard font size for texts}}
| If checked, imported texts will get the standard [[Draft_Text|Draft Text]] size, instead of the size they have in the DXF document
|-
|-
| {{MenuCommand|Use VisGroups}}
| {{MenuCommand|Macro path}}
| Specifies the path for macro files.

|-
|-
| {{MenuCommand|Render polylines with width}}
| {{MenuCommand|Record as comment}}
| If checked, [[Std_DlgMacroRecord|recorded macros]] will also contain user interface commands, but as comments. This is useful if you don't want to execute these commands when running the macro, but do want to see what has been done while recording.
| If checked, when polylines have a width defined, they will be rendered as closed wires with the correct width
|-
|-
| {{MenuCommand|Treat ellipses and splines as polylines}}
| {{MenuCommand|Show script commands in python console}}
| If checked, the commands executed by macro scripts are shown in the Python console. This console can be opened using the {{MenuCommand|View → Panels → Python console}} menu option.
| The export of ellipses and splines is poorly supported. ??Still the case?? Use this option to export them as polylines instead.<br/>The setting '''Max Spline Segment''' is then the maximum length of each of the polyline segments. If it is set to '0' the whole spline is treated as a straight segment.
|-
|-
| {{MenuCommand|Export 3D objects as polyface meshes}}
| {{MenuCommand|Size of recent macro list}}
| Controls the number of recent macros to display in the menu.
| If checked, all objects containing faces will be exported as 3D polyfaces
|-
|-
| {{MenuCommand|Export Drawing Views as blocks}}
| {{MenuCommand|Shortcut count}}
| Controls the number of recent macros that get dynamically assigned shortcuts.
| If this is checked, Drawing Views will be exported as blocks. This might fail for post DXF R12 templates.
|-
|-
| {{MenuCommand|Project exported objects along current view direction}}
| {{MenuCommand|Keyboard Modifiers}}
| Controls which keyboard modifiers are used for the shortcuts, example '''Ctrl+Shift+''' creates shortcuts in the form of '''Ctrl+Shift+1''', '''Ctrl+Shift+2''', etc.

===IGES===


===Python console===
The [https://en.wikipedia.org/wiki/IGES Initial Graphics Exchange Specification] (IGES) file format is a file format that allows the digital exchange of information among CAD systems. Since the specification for the [[Preferences_Editor#STEP|STEP]] file format was published, the development of IGES was stopped in 1996. It is nevertheless still supported by many CAD programs.


These preferences control the behavior of the [[Python_console|Python console]]. This console can be opened using the {{MenuCommand|View → Panels → Python console}} menu option.
The tab ''IGES'' is only shown in the preferences if you are in the [[Part_Module|Part]] or [[PartDesign_Workbench|PartDesign]] workbench or if you have been in these workbenches before.<br/>For the IGES format you can specify the following:

Note that the color and font settings for the console are defined on the [[#Editor|Editor]] tab.

===IFC===


<span id="Editor"></span>
[http://en.wikipedia.org/wiki/Industry_Foundation_Classes Industry Foundation Classes] (IFC) is a wide spread format to interchange data between [http://en.wikipedia.org/wiki/Building_Information_Modeling BIM] applications, used in architecture and engineering.
===编辑器===

These preferences control the behavior of the [[Std_DlgMacroExecute#Edit|Macro editor]]. This editor can be opened using the {{MenuCommand|Macro → Macros... → Edit}} or {{menuCommand|Create}} menu option.

The color and font settings are also used by the [[#Python_console|Python console]].


For the IFC format you can specify the following:
On the ''Editor'' tab you can specify the following:

| If checked, all FreeCAD object properties will be stored inside the exported objects, allowing to recreate a full parametric model on reimport.
|-
| {{MenuCommand|Reuse similar entities}}
| If checked, similar entities will be used only once in the file if possible. This can reduce the file size a lot, but will make it less easily readable by humans.
|-
| {{MenuCommand|Disable IfcRectangleProfileDef}}
| When possible, IFC objects that are extruded rectangles are exported as [http://www.buildingsmart-tech.org/ifc/IFC4/Add1/html/schema/ifcprofileresource/lexical/ifcrectangleprofiledef.htm IfcRectangleProfileDef]. However, some other applications have problems importing that entity. If this is your case, you can disable this and then all profiles will be exported as [http://www.buildingsmart-tech.org/ifc/IFC4/Add1/html/schema/ifcprofileresource/lexical/ifcarbitraryclosedprofiledef.htm IfcArbitraryClosedProfileDef].

Introduction

FreeCAD 的首选项位于菜单栏中的 编辑 → 首选项。

FreeCAD 的功能被分为了不同的模块,每个模块负责某个具体工作台的相关工作。FreeCAD 还使用了一种称之为后加载的观念,意即相关组件只有在需要时才被加载进来。或许你已经注意到,当你在 FreeCAD 工具栏中选择一个工作台时,此工作台和它的所有组件都同时被加载进来。这其中包含了它的首选项设置。

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.

如果没有载入任何模块,将会有两项配置部分,一项是对一般的应用设置,另一项则对显示设置。

单击任何首选项显示左下角的重置 按钮,将freecad首选项的“全部”设置为其默认值。

Some advanced preferences can only be changed in the Parameter editor. The Fine-tuning page lists some of them.

一般的首选项设置

在刚启动 FreeCAD 时没有加载工作台,此时出现的是最小首选项窗口。随着其它模块的载入,最小首选项窗口中就会出现新的部分,此时可以对每个工作台的细节进行配置。

In version 0.21 and below the seventh tab, Help, is only available if the Help Addon has been installed.

通用

Name Description
Language Language of the application's user interface.
Default unit system Unit system for all parts of the application. introduced in version 1.0: Used as the default for the document unit system of new documents.
Number of decimals The number of decimals that should be shown for numbers and dimensions.
Ignore project unit system and use default introduced in version 1.0 If checked, project unit systems are ignored and do not override the default unit system.
Minimum fractional inch The minimum fractional inch that should be shown for numbers and dimensions. Only available for unit systems with fractional inches.
Number format introduced in version 0.20 Specifies the number format. The options are:
  • Operating system: The decimal separator defined by the operating system is used.
  • Selected language: The decimal separator of the selected FreeCAD interface language is used.
  • C/POSIX: A point is used as the decimal separator.
Substitute decimal separator introduced in version 0.20 If checked, the numerical keypad decimal separator will be substituted with the separator defined by the Number format setting. introduced in version 0.21: Notice that if this preference is enabled, using the numerical keypad decimal separator will always print a dot/period in the Python console and the Macro editor.
Theme Specifies a theme to customize the appearance of the user interface.
Size of toolbar icons Specifies the size of the toolbar icons. The options are:
  • Small (16px)
  • Medium (24px)
  • Large (32px)
  • Extra large (48px)
Tree view mode Defines how the tree view is shown in the user interface (restart required). The options are:
  • Combo View: Combines the tree view and the property view into one panel.
  • TreeView and PropertyView: Splits the tree view and the property view into separate panels.
  • Both: Shows all three panels. version 0.21 and below
Size of recent file list Specifies how many files should be listed in the recent files list.

Optionally, imported files can be excluded from this list, and exported files can be included. See Fine-tuning.

Enable tiled background If checked, the background of FreeCAD's main window will by default consist of tiles of this image:

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.

Enable splash screen at start up If checked, a splash screen is shown when starting FreeCAD.

The splash screen image can be changed by placing a file named splash_image.png in the Images folder already mentioned under Enable tiled background.

Enable cursor blinking If checked the text cursor in the Python console and the Macro editor will blink.
Activate overlay handling introduced in version 1.0 If checked, docked windows can be handled as transparent overlays.
Preference packs introduced in version 0.20 Lists the available preference packs and also allows you to import, save, manage and revert them.

文档

On the Document tab you can specify the following:

Name Description
Create new document at start up If checked, FreeCAD will create a new document when started.
Document save compression level Specifies the compression level for FCStd files. FCStd files are ZIP-compressed files. Therefore you can rename their suffix .FCStd to .zip and open them with a ZIP archive program.
Using Undo/Redo on documents If checked, all changes in documents are stored so that they can be undone/redone.
Maximum Undo/Redo steps Specifies how many Undo/Redo steps should be recorded.
Allow aborting recomputation If checked, recomputations can be aborted by pressing Esc. This may slightly increase the recomputation time.
Run AutoRecovery at startup If there is a recovery file available FreeCAD will automatically run a file recovery when it is started. This way files can be restored if a crash occurred.
Save AutoRecovery information every Specifies how often a recovery file is written.
Save thumbnail into project file when saving document If checked, a thumbnail will be stored when the document is saved. The thumbnail will for example be shown in the list of recent files in the Start Workbench. It is possible to select a Size between 128×128 and 512×512 pixels for the thumbnail. Common sizes are powers of two: 128, 256, 512.
Add the program logo to the generated thumbnail If checked, the FreeCAD program logo will be added to the thumbnail.
Maximum number of backup files to keep when resaving document 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.
Use date and FCBak extension 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 Date & time formats cheatsheet.

With the default settings a backup file will for example get this name TD-Cube.20200315-215654.FCBak (original filename is TD-Cube.FCStd).

Allow duplicate object labels in one document If checked, objects can have the same label.
Disable partial loading of external linked objects If partial loading of external linked objects is enabled, only the referenced objects and their dependencies will be loaded when the linked document is auto opened together with the main document. Such a partially loaded document cannot be edited. Double click the document icon in the tree view to reload it in full. A more detailed explanation of this feature can be found on the Assembly3 documentation page.
Author name All created documents will get the specified author name. Keep the author field blank if you do not want to include this information. If the option Set on save is checked, the field Last modified by will be set to the specified author when saving the file. This field can be viewed using the File → Project information menu option.
Company All created documents will get the specified company name.
Default license Specifies the license for new documents. For predefined licenses the License URL will automatically be set accordingly. Select Other for a custom license.
License URL Specifies an URL describing the license selected in Default license.

Selection

On the Selection tab you can specify the following:

反转缩放=

反转缩放操作的方向。

On the 3D View tab 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 (introduced in version 0.20) defines the size of the representation as a percentage of the view size (the minimum of its height and width).

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 software OpenGL If checked, OpenGL will use the CPU instead of the GPU. This option is useful for troubleshooting graphics card and driver problems. Changing this option requires a restart of the application.
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:
  • Auto: Let Coin3D decide where to cache (default).
  • Distributed: Manually turn on cache for all view provider root nodes.
  • Centralized: Manually turn off cache in all nodes of all view providers, and only cache at the scene graph root node. This offers the fastest rendering speed, but slower response to any scene changes.
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:
  • One pass: Rendering is done in one pass (default). This can lead to triangular artifacts. If these occur the type Backface pass can be used to avoid them.
  • Backface pass: Rendering is done in two passes. Back-facing polygons are rendered in the first pass and front-facing polygons in the second pass.
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.
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 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:

Navigation

On the Navigation tab you can specify the following:

Name Description
Navigation cube If checked, the Navigation cube will be 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. introduced in version 0.20

Cube size defines the size of the cube. introduced in version 0.20

Color sets the base color for all elements. introduced in version 0.21

Corner defines where the Navigation cube is displayed in the 3D view. The options are:

  • Bottom left
  • Bottom right

Font name specifies the font used for the cube's texts. introduced in version 0.21

Font size sets the size of the font used for the cube's texts. introduced in version 0.21

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:
  • Turntable: Moving the mouse will divide the rotation in steps, rotations around the different axes are performed sequentially.
  • Trackball: Rotations around the different axes are performed simultaneously.
  • Free Turntable: Like Trackball, but if possible the rotation axis is kept collinear with the global 3D view axis. introduced in version 0.21
Rotation mode Defines the rotation center. The options are:
  • Window center
  • Drag at cursor
  • Object center
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 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).
Enable animation If checked, and 3D Navigation is set to CAD, rotations can be animated. 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.
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 rotation center indication If checked, the rotation center of the view is shown when dragging. introduced in version 1.0

颜色

On the Colors tab you can specify the following:

Name Description
Enable preselection highlighting If checked, preselection is turned on and the specified color will be used for it. Preselection means that for example edges of objects 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 specified color.
Linear gradient If selected, the background of the 3D view will have a vertical color gradient defined by the specified Top and Bottom colors. if enabled, a Middle color can also be specified. Press the button (introduced in version 0.21) to switch the top and bottom colors.
Radial gradient introduced in version 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 button to switch the central and end colors.
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.

Mesh view

This tab is only available if the Mesh Workbench has been loaded.

On the Mesh view tab 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 ViewLighting 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 ViewSelection 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.
If face angle ≥ crease angle, facet shading is used.
If face angle < crease angle, smooth shading is used.
