The default spacing between baseline dimensions can be set from the Dimension Style
Manager, Lines tab, Baseline Spacing (DIMDLI system variable).

If no dimension was created in the current session, you are prompted to select a linear,
ordinate, or angular dimension to use as the base for the baseline dimension. To end
the command, press Enter twice, or press Esc. The current dimension style determines
the appearance of the text.

By default, the dimension style of the baseline dimension is inherited from the previous
or selected dimension. You can use DIMCONTINUEMODE to change the default to use the
current dimension style.

The following prompts are displayed.

Select Base Dimension

Specifies a linear, ordinate, or angular dimension. Otherwise, the program skips this
prompt and uses the dimension object that was last created in the current session.

Second Extension Line Origin

If the base dimension is linear or angular, this prompt is displayed. By default,
the first extension line of the base dimension is used as the extension line origin
for the baseline dimension. To override this default behavior, explicitly select the
base dimension; the extension line origin becomes the extension line of the base dimension
closest to the pick point of the selection. When you select a second point, the baseline
dimension is drawn and the Specify a Second Extension Line Origin prompt is redisplayed.
To end the command, press Esc. To select another linear, ordinate, or angular dimension
to use as the basis for the baseline dimension, press Enter.

Feature Location

If the base dimension is ordinate, this prompt is displayed. Uses the endpoint of
the base dimension as the endpoint for the baseline dimension; you are prompted for
the next feature location. When you select a feature location, the baseline dimension
is drawn and the Specify Feature Location prompt is redisplayed. To select another
linear, ordinate, or angular dimension to use as the basis for the baseline dimension,
press Enter.

Undo

Undoes the last baseline dimension entered during this command session.

Select

Prompts you to select a linear, ordinate, or angular dimension to use as the base
for the baseline dimension.
