Using Inward Dimension
Inwards Dimension will cause the arrows to be positioned outside the outer edges of the dimension, pointing inwards.
If Inwards Dimension is deselected then the arrows will be positioned within the dimension, pointing outwards. This is the normal mode of operation, but the arrows will flip the other way if the text does not also fit within the dimension.
This dimension parameter can also be changed using Dimension Properties.
