SERIAL allows you to create a series of dimensions.

Indicate the type of serial dimension you want to use by
choosing from the following options:

CHAIN - to create chain dimensioning. You can select a
maximum of 50 reference points for chain dimensions.

BASELN - to create a series of dimensions that have one
reference point (the baseline point) in common. The
dimensions are stacked so that dimensions of lesser value
are displayed below dimensions of larger value. You can
select a maximum of 50 reference points.

Please be aware of the following notes:

* Baseline dimensions are only displayed in the view in
  which they are created.
* You must select all points of a baseline dimension 
  before you create the actual dimension.
* To automatically center dimension text, use DETAIL, SET,
  TEXT, DIM PLC, AUTO CEN.

RUNNING - to create a superimposed running dimension; a
chainlike series of dimensions that have one reference 
point (the baseline point) in common. Unlike baseline and
chain dimensions, the text is placed at the top of the
witness line and the text's angle is the same as the 
witness line. The dimensions are all displayed at the
witness line height indicated. You can select a maximum
of 50 reference points.
