Object Selection Automatically determines the origin points of the first and
second extension lines after you select an object.
For polylines and other explodable objects, only the individual line and arc
segments are dimensioned. You cannot select objects in a nonuniformly scaled
block reference.
If you select a line or an arc, its endpoints are used as the origins of the
extension lines. The extension lines are offset from the endpoints by the
distance specified in Offset from Origin on the Lines and Arrows tab of the
New, Modify, and Override Dimension Style dialog boxes (see DIMSTYLE
(page 314)). This value is stored in the DIMEXO (page 1231) system variable.
If you select a circle, the endpoints of its diameter are used as the origins of
the extension line. The point used to select the circle defines the origin of the
first extension line.
Dimension Line Location Specifies the placement of the dimension line and
determines the direction to draw the extension lines. After you specify the
location, the DIMALIGNED command ends.
Mtext Displays the
In-Place Text Editor (page 675), which you can use to edit
the dimension text. The generated measurement is represented with angle
brackets (< >). To add a prefix or a suffix to the generated measurement, enter
the prefix or suffix before or after the angle brackets. Use control codes and
Unicode character strings to enter special characters or symbols. See
Control
Codes and Special Characters
(page 1049).
To edit or replace the generated measurement, delete the angle brackets, enter
the new dimension text, and then click OK. If alternate units are not turned
on in the dimension style, you can display them by entering square brackets
([ ]). For more information, see Select and Modify Objects.
The current dimension style determines the appearance of the generated
measurements.
