This value is also used as the minimum length required for dimension line segments.

Text is positioned inside the extension lines only if the resulting segments are at least as long as the text gap. Text above or below the dimension line is placed inside only if the arrowheads, dimension text and a margin leave enough room for the text gap.

Examples:

1. Offset from dim line: 0.625

2. Offset from dim line: 0

Horizontal:

Over dimension line, with leader:

If selected, dimension lines are not moved when text is moved. If text is moved away from the dimension line, a leader line is created connecting the text to the dimension line.

The leader line is omitted when text is too close to the dimension line.

Over dimension line, without leader:

If selected, dimension lines are not moved when text is moved.
