Use control codes and Unicode character strings to enter special characters or symbols. Mtext Displays the In-Place Text Editor, which you can use to edit the dimension text. Dimension Line Location Uses the point you specify to locate the dimension line. This value is stored in the DIMEXO system variable. 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. If you select a line or an arc, the line or arc endpoints are used as the origins of the extension lines. If you select a circle, the location of the origins for the extension lines is calculated based on the center and diameter of the circle, and the angle of the rotated dimension line. You can also select a segment of a polyline or object in a uniformly scaled block. Select Object Automatically determines the origin points of the first and second extension lines after you select the object to be dimensioned. First Extension Line Origin Specifies the two points to determine the origin points of the extension lines. Specify Angle of Dimension Line Specifies a rotation angle for the dimension line relative to the X axis of the UCS.
