When selected, the field for setting the witness line length is enabled on the top part of the dialog box. To change the length of a particular witness line, use the Override option in the Object Info palette.
Dimensions Always Inside	When selected, the dimension value is always centered between the witness lines. When deselected, the dimension value is automatically positioned outside the witness lines if it is too large to fit between them.
