How to reproduce: Tools - Options - Language Settings - Language: User Interface: English (USA) Locale Setting: English (USA) Default Language of Documents: Western: English (USA) Asian: Chinese (Traditional) Set Draw-General-Unit of Measurement to "Centimeter", close, re-open Draw. Unit of Mesaurement reset to "Inch" automatically. Writer, though have similar Unit of Measurement settings, does not have the above problem. Tested Platform: Windows 7 64bit Home Edition (US English) Affected Libreoffice versions: 3.6.4.3 (tested) 4.00 beta 2 (tested) Reference - Similar Problem: bug 57915
Note: If I directly edit and save the default template using Centimeter, Draw opens a new drawing in Centimeter, but if I check Options-Draw-View-Display-Rulers Visible to "Off" (uncheck the box), click "OK" button, and then check Rulers Visible to "On" again (check the box). Draw resets all units to "Inch" again.
