### Parameters of Dimensioning

Hereafter, you will find an overview of a few parameters that help you change the look of your dimensioning.
You can obtain detailed explanations in the online help system.

- Location of the dimension line
  The location of the dimension line is determined by the point for dimension line ( PDL ) you enter.

- Contents of the Nominal Dimension
  In the most simple case, the nominal dimension holds the value of the distance or the angle between the referenced elements. You can multiply this number by a user-supplied factor ( NSF ), or you can highlight it as e.g. a test dimension using a dimension identifier ( DID ).
  You can set the nominal dimension to an arbitrary text ( NS ), or you can pre- ( NSPRE ) or postfix ( NSPOST ) the value with a text.
  The nominal value representation ( NSR ) is used mainly for parametric dimensions, to control the representation of the name, the formula or the dimension value in the nominal dimension.

- Contents of the complete Dimension Text
  The nominal dimension described above is a part of the dimension text. To design your dimension text, you can use the following parameters:

  > DEVH (DEViation High), DEVL (DEViation Low),
  > RIDX (Revision InDeX), NSTA (Nominal Size Text After)
  > and NSTB (Nominal Size Text Before).

  > RIDX (Revision InDeX), DEVH (DEViation High), DEVL (DEViation Low), NSTA (Nominal Size Text After) and NSTB (Nominal Size Text Before).

- Location of the dimension text
  If you do not choose to position the dimension text freely, it will be positioned along the dimension line.
  The location SISCAD-P chooses for the dimension text may not always agree with your preferences. To position the text according to your taste, you can use the parameter for dimension text position PDT (resp. NPDT when changing), or else work with the parameter leader line ( LLIN ).

Most dimensioning parameters can be set in the configuration defaults, so that you can achieve a standard look in your dimensioning.
