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:


 * Mod/Part/ParametricRefine (boolean) : Set to so Part RefineShape creates an independent copy rather than a linked one.
 * Mod/PartDesign/SwitchToTask (boolean): Set to to prevent the PartDesign Workbench from switching to the Task panel when starting.
 * Mod/PartDesign/SwitchToWB (boolean): Set to to prevent the PartDesign Workbench to be automatically called when a PartDesign Body is activated.
 * Document/SaveThumbnailFix (boolean): Set to to fix a problem with Qt5 that prevents the generation of  file thumbnails.
 * TechDraw has several hidden switches documented in TechDraw Preferences.
 * View/SavePicture (string): Set to FramebufferObject, PixelBuffer or CoinOffscreenRenderer for different methods to produce images from the 3D view
 * 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
 * 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.
 * 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/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.
