arc length dimension placements

Hi,

I am dimensioning a radial plate to show stiffener positions around the inside / outside radius.

The dimensions look fine until I get past half way then they flip over and do not look correct.

How can I flip them so they all look the same.

Please see attached word doc for an example.

Thanks
