BASELN allows you 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 for baseline
dimensions.

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.

Select the axis for the baseline dimensions by choosing 
from the following options:

HORIZTL - to display baseline dimensions horizontally
          between the selected points.

VERTICL - to display baseline dimensions vertically 
          between the selected points.

PARALEL - to display baseline dimensioning parallel to the
          general direction of the selected points, 
          according to the indicated axis position. 
          Indicate the axis you want as your dimension
          axis by selecting two positions. 

Indicate the base position of the dimension by choosing a
Position Menu option. This position is the common 
reference point for the baseline dimensions.

Select, in any order, the positions (up to a maximum
of 50) you wish to dimension to from the indicated base 
position.

Press <Enter> when you have finished selecting the
positions.

Select a position to indicate the witness line height. 
This position is used to calculate the witness and leader
lines for the first dimension. The witness lines for 
subsequent dimensions are raised by twice the dimension
text height of the first dimension.

Two temporary lines are displayed on the screen to 
indicate the boundaries of the dimension to be processed.

Indicate the dimension text position. This position
determines the run, not the rise (or height) of the
placement of the dimension text. It is projected to the
current witness height line. When you place the text, the
dimensioning is calculated from the base point to the
indicated positions, in sequential order, starting with 
the positions closest to the base point.

The dimension is displayed, along with its leader lines.

Indicate whether or not you want to accept the dimensions.
If you choose NO, the dimension and its leader lines are
deleted and the temporary witness lines remain highlighted
until a new dimension text position is indicated. If you
choose YES, the dimension is accepted and is displayed 
along with its witness lines.

As each dimension is processed, temporary witness lines
indicating the next dimension to be processed are 
displayed at the new height (i.e., the old height plus two
times the dimension text height).

Continue until all of the dimensions are processed.
