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.
 * 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
