Dimordinate - Autodesk AUTOCAD 2006 Command Reference Manual

If you select a line or an arc, the line or arc endpoints are used as the origins
of the extension lines. The extension lines are offset from the endpoints by
the distance you specify in Offset from Origin in the Lines and Arrows tab of
the New, Modify, and Override Dimension Style dialog boxes. See DIMSTYLE.
This value is stored in the DIMEXO system variable.

used to select the circle is close to the east or west quadrant point, a vertical
dimension is drawn.
