Fine-tuning

This page holds different settings and parameters that you can use to fine-tune your FreeCAD installation or overcome problems.

Option parameters
The FreeCAD Preferences Editor under menu is commonly used to set and manipulate the FreeCAD parameters table.

However, it is also possible to access, modify and create parameters manually, using the Parameter Editor found under menu.

The list below shows parameters that are not accessible via the preferences editor, but that you can set manually (located in BaseApp/Preferences)


 * Bitmaps/Theme/ThemeSearchPaths (boolean) : Set to so FreeCAD uses it's included icons instead of the system icon theme on Linux.
 * DockWindows/DAGView/Enabled (boolean): Set to to enable a beta DAG view dockable widget. After changing the parameter value, a FreeCAD restart is needed so the widget is available in the View/Panels list.
 * DockWindows/PropertyView/Enabled (boolean): Set to to enable a Property View dockable widget independent from the Combo View. After changing the parameter value, a FreeCAD restart is needed so the widget is available in the View/Panels list.
 * DockWindows/TreeView/Enabled (boolean): Set to to enable a Tree View dockable widget independent from the Combo View. After changing the parameter value, a FreeCAD restart is needed so the widget is available in the View/Panels list.
 * Document/ChangeViewProviderTouchDocument (boolean) : Set to so items visibility changes won't mark the document as changed.
 * Document/SaveThumbnailFix (boolean): Set to to fix a problem with Qt5 that prevents the generation of  file thumbnails.
 * General/RecentIncludesExported (boolean): Set to to include exported files in the Recent Files list. Defaults to.
 * General/RecentIncludesImported (boolean): Set to to exclude imported files from the Recent Files list. Defaults to.
 * Mod/Draft/defaultCameraHeight (int) : Sets the height of the camera when Draft starts in an empty document. 0 disables, FreeCAD default is 5, good when working in millimeters, a good height for arch work is 4500.
 * Mod/Part/ParametricRefine (boolean) : Set to so Part RefineShape creates an independent copy rather than a linked one. Defaults to.
 * Mod/PartDesign/AdditiveHelixPreview (boolean): Set to to ensure an additive helix that does not intersect the body is visible in the preview. Defaults to.
 * Mod/PartDesign/SubtractiveHelixPreview (boolean): Set to to ensure a subtractive helix that does not intersect the body is visible in the preview. Defaults to.
 * Mod/PartDesign/SwitchToTask (boolean): Set to to prevent the PartDesign Workbench from switching to the Task panel when starting. Defaults to.
 * Mod/PartDesign/SwitchToWB (boolean): Set to to prevent the PartDesign Workbench to be automatically called when a PartDesign Body is activated. Defaults to.
 * PropertyView/AutoTransactionView (boolean) : Set to so changes of View tab properties are added to the undo stack (hence are undoable). Defaults to.
 * View/NavigationDebug (boolean) : enables debug output of navigation styles (as of v0.19, only Gesture navigation style has something to say).
 * View/SavePicture (string): Set to FramebufferObject, PixelBuffer or CoinOffscreenRenderer for different methods to produce images from the 3D view.

Export Default Filename

 * General/ExportDefaultFilenameMultiple (string): Set the default filename to use when exporting multiple objects. Defaults to "%F".
 * General/ExportDefaultFilenameSingle (string): Set the default filename to use when exporting a single object. Defaults to "%F-%P-".

Both of these options support the automatic insertion of various pieces of information into the filename, using the following format characters: Any other characters are treated literally. If the resulting filename is illegal it will be changed on saving, with illegal characters replaced by the underscore (_).
 * %F - the name of the .FCStd file (or the label, if it is not saved yet)
 * %Lx - the label of the selected object(s), separated by character 'x'
 * %Px - the label of the selected object(s) and their first parent, separated by character 'x'
 * %U - the date and time, in UTC, ISO 8601
 * %D - the date and time, in local timezone, ISO 8601

Mouse related

 * General/ComboBoxWheelEventFilter (boolean) : Set to so widgets do not catch mouse wheel event and prevent scrollable areas to be scrolled.
 * View/GestureMoveThreshold (integer) : the distance (px) mouse cursor has to move to enter rotation or pan modes of Gesture navigation style. Default is 5.
 * View/GestureRollFwdCommand, View/GestureRollBackCommand (string) : commands to be executed by mouse button roll gestures of Gesture navigation style.
 * View/GestureTapHoldTimeout (integer) : sets for how long to wait (in milliseconds) to enter pan mode in Gesture navigation style. It can be helpful to increase it if dragging geometry in sketcher is difficult. Default is 700.

Escape Key

 * General/TasksKeyEsc (boolean) : Create and set to to disable the  key exiting the Task panel in all workbenches (that is if the task panel has focus). Note: Superceded by Sketcher Preferences.
 * Mod/Sketcher/ViewKeyEsc (boolean) : Create and set to to disable  key issues with pressing one to many times, when escaping sketcher geometry/constraints creation continue mode (see forum thread)

Specific Workbenches

 * [[Image:Workbench_TechDraw.svg|16px|link=TechDraw_Workbench]] TechDraw Workbench has several hidden switches documented in TechDraw Preferences.
 * [[Image:Workbench_Path.svg|16px|link=Path_Workbench]] Path Workbench has a switch to enable experimental features documented in Path experimental.
 * [[Image:Workbench_BIM.svg|16px|link=BIM_Workbench]] BIM Workbench:
 * Mod/BIM/DefaultPageScale (float): Default scaling for new TechDraw pages created from the BIM Workbench, in case the template doesn't contain any "Scale" or "Scaling" (text insensitive) editable text field.
