• When you right-click a dimension and click Flip Arrows, the witness lines get erased. • If you change the Configuration setting of a diameter dimension from  Leader to  Linear, witness lines associated with the Leader configuration are removed. If you again change the Configuration setting to Leader, you will have to recreate the witness lines. |
