Threshold for moving text to the side of a linear dimension - where is it set?

Thanks, but I can’t assess the gumball-related issue further. I am working with dimensions in VisualArq at the moment and there are anomalies relating to that which may be interfering with or causing this issue. (Dimension Shift With Detail Window Activation/Deactivation) (Those issues with History/Associativity and VIsualArq might benefit from your thoughts.)

However:

1) Setting Text side-placement threshold I’d like to be able to set the threshold for when the text shifts over to the side of a dimension rather than displaying in the middle, so I don’t have to move the text around when it doesn’t fit, or after Rhino has moved it over.
