    You could look at the Route - unsupported Prototypes - resize/respace diff pairs command, pick the diff pairs you are interested in and change the values.

    the info below is from another forum posting:

    The Resize/Respace Diff Pairs command ignores 45-degree traces when tolerances are set to 0. From Setup > Constraints > Physical > Differential Pair >  (+)Tolerance, set it to an appropriate small value, but non-zero. This will apply the modified spacing to the angled traces.

    I change the value of  (+)Tolerance to 0.1. but it still isn't work. Display some error messages as show in the picture. "canot respace diff-pair segment at or near".

    Note that, the diff-pair contains arc.
