Draft Preferences

The preferences for the Draft Workbench are found in the Preferences Editor, in the menu.

There are four tabs: General settings, Grid and snapping, Visual settings, and Texts and dimensions.

General settings
It has General settings, where you can specify the color of the snap symbols, the default width and color for new objects. By checking the "Save current color and linewidth across sessions" checkbox, any change you make on the draft command bar will be saved here, so you will start your next FreeCAD session with the color and width you were using on quit.
