底图工作台的首选项可以在首选项编辑器中找到,它位于Edit → Preferences → Draft菜单。

此处有4个选项卡:通用设置、网格与捕捉、可视化设置,以及文本与标注。

通用设置

On the General settings tab you can specify the following:

Name Description
Default working plane The initial working plane when the Draft Workbench is first loaded in a FreeCAD session. The options are:
  • None: this is equivalent to the Automatic option of the Draft SelectPlane command.
  • XY (Top)
  • XZ (Front)
  • YZ (Side)
Internal precision level The number of decimals used in internal coordinate operations (for example 3 = 0.001). Values between 6 and 8 are usually considered the best trade-off.

After changing this preference you must restart FreeCAD.

Tolerance Some internal operations use a tolerance. Values with differences below this value will be treated as the same. This preference will be obsoleted soon, the Internal precision level mentioned above will then be used for the tolerance as well.

After changing this preference you must restart FreeCAD.

Show groups in layers list drop-down button If checked, the layers drop-down list will also show groups, allowing you to automatically add objects to groups as well. See Draft AutoGroup.
Set focus on Length instead of X coordinate Set the focus on the Length input box, if available, instead of the X coordinate input box. This allows to specify a direction and a distance to define the next point.
Select base objects after copying If checked, the base objects are reselected after copying objects.
Set the Support property when possible If checked, when creating a Draft object on top of the selected face of an existing object, the 数据Support property of the Draft object will be set to that base object. This was standard behavior before FreeCAD version 0.19.
Fill objects with faces whenever possible If checked, commands will start with filled mode switched on. If filled mode is on, the created objects will have 数据Make Face set to true. Changing the filled mode in a task panel will override this preference for the current FreeCAD session.

After changing this preference you must restart FreeCAD.

Global copy mode If checked, copy mode will be kept across commands. Otherwise commands will always start with copy mode switched off.
Use Part Primitives when available If checked, Draft commands create Part primitives instead of Draft objects when possible. Note that not all Part primitives are fully editable with the Draft modifier commands.
Prefix labels of Clones with The default prefix added to the labels of Draft clones.
Construction group name The default name (FreeCAD version 0.19) or the default label (FreeCAD version 0.20) for the Draft construction group.
Construction geometry color The default color for objects drawn while in construction mode.

User interface settings

On the User interface settings tab you can specify the following:

Name Description
In-Command Shortcuts These shortcuts only work when a Draft or Arch command is active. Note that not all commands support all shortcuts.

After changing on or more of these shortcuts you must restart FreeCAD.

Relative Shortcut to toggle relative mode. If relative mode is on, coordinates are relative to the last point, if available, else they are relative to the coordinate system origin.
Continue Shortcut to toggle continue mode. If continue mode is on, commands will restart after finishing.
Close Shortcut to press the Close button.
Copy Shortcut to toggle copy mode. If copy mode is on, the command will create modified copies instead of modifying the original objects.
Subelement Mode Shortcut to toggle subelement mode. If subelement mode is on, the command will use the selected subelements instead of the whole objects.
Fill Shortcut to toggle filled mode. If filled mode is on, the created object will have 数据Make Face set to true.
Exit Shortcut to press the Finish button.
Select Edge Shortcut to press the Select edge button. See Draft Dimension.
Add Hold Shortcut to insert a "hold point" at the current location of the cursor. See Draft Snap.
Length Shortcut to change the focus from the X coordinate input box to the Length input box and vice versa.
Wipe Shortcut to press the Wipe button.
Set WP Shortcut to press the Set WP button.
Cycle Snap Shortcut to change snap priority to an object that is obscured by other geometry. See Draft Snap.
Global Shortcut to toggle global mode. If global mode is on, coordinates are relative to the global coordinate system, else they are relative to the working plane coordinate system. introduced in version 0.20
Snap Shortcut to toggle Draft snapping.
Increase Radius Shortcut to increase the maximum distance at which Draft Snap Grid detects the intersections of grid lines. See Draft SelectPlane.
Decrease Radius Shortcut to decrease the maximum distance at which Draft Snap Grid detects the intersections of grid lines.
Restrict X Shortcut to constrain the movement of the cursor to the X axis. See Draft Constrain.
Restrict Y Shortcut to constrain the movement of the cursor to the Y axis.
Restrict Z Shortcut to constrain the movement of the cursor to the Z axis.
Draft Statusbar This option does not work properly, it should always be checked.
Draft snap widget If checked, the Draft snap widget is enabled.

After changing this preference you must restart FreeCAD.

Annotation scale widget If checked, the Draft annotation scale widget is enabled.

After changing this preference you must restart FreeCAD.

网格与捕捉

Note that several grid preferences can also be changed with the Draft SelectPlane command. This command will update the grid in the current 3D view in real-time.

On the Grid and snapping tab you can specify the following:

Name Description
Always snap (disable snap mod) If checked, snapping is activated without the need to press the Snap mod key.
Constrain mod The Constraining modifier key.

After changing this preference you must restart FreeCAD.

Snap mod The Snap modifier key.

After changing this preference you must restart FreeCAD.

Alt mod The Alt modifier key. The function of this key depends on the command.

After changing this preference you must restart FreeCAD.

Show Draft Snap toolbar If checked, the Snap toolbar will be shown whenever a command is active. This option and the next option should both be checked or unchecked. Other combinations do not make sense.
Hide Draft snap toolbar after use If checked, the Snap toolbar will be hidden after use. This option and the previous option should both be checked or unchecked. Other combinations do not make sense.
Use grid If checked, a grid will appear when drawing.

After changing this preference you must restart FreeCAD.

Always show the grid If checked, the Draft grid will always be visible when the Draft Workbench or Arch Workbench is active. Otherwise only when using a command.
Show grid border If checked, an additional border is displayed around the grid, showing the main square size in the bottom left corner.

After changing this preference you must open a new 3D view or restart FreeCAD.

Show human figure If checked, the outline of a human figure is displayed at the bottom left corner of the grid, provided Show grid border mentioned above is also checked, and the BIM Workbench is installed. introduced in version 0.20

After changing this preference you must use Draft ToggleGrid twice or restart FreeCAD.

Use colored axes If checked, the two main axes of the grid will be colored red, green or blue if they match the X, Y or Z axis of the global coordinate system.

After changing this preference you must use Draft ToggleGrid twice or restart FreeCAD.

Main lines every The number of squares between main grid lines. These lines are thicker than normal grid lines.

After changing this preference you must use Draft ToggleGrid twice or restart FreeCAD.

Grid spacing The distance between grid lines.

  • text inside (3D): the dimension text always faces the camera.
Number of decimals The number of decimal places to display for the dimension text.
Extension lines size The length of the extension lines below the dimension line.
