The Entity Modification tab of the Drawing Settings dialog box controls the way entities are edited, such as how text is mirrored, how corners are filleted, and how lines are trimmed. From the Change Settings For list, choose Chamfer/Fillet, Spline/Fit, or Trim/Extend to set Entity Modification defaults.
