«Alternative dimension» section
Show. This parameter determines the presence or absence of an alternative
dimension in the drawing. When the parameter is set to “Default”, then its
setting is defined on the “Alternative dimensions” tab of the “ST: Set
Model Status” (“Service/Status…”) command dialog.
Separator. This parameter sets the appearance of separators that are used in
the drawing to separate the alternative and the main dimension values:
Default. In this case, the separator assumes the type defined in the command
“Customize|Status…”.
None. The alternative dimension text will not be separated.
[Brackets]. The alternative dimension text will appear in brackets.
{Braces}. The alternative dimension text will appear in braces.
Position. This parameter defines the mode of displaying the alternative
dimension value in the drawing at a relative location of the main dimension
value. According to the choice made, the alternative dimension value will
appear in the drawing “After”, “Before”, “Under” or “Above” the main
dimension value string. If the parameter is defined as “Default”, then its
value is assumed from the “Alternative dimensions” setting of the
command “Customize|Status…”.
Scale. this parameter defines the scale factor of an alternative dimension (which is fully analogous to the
scale factor of the main dimension value).
Why are «Alternative scale» and «Scale factor», respectively? Suppose, dimension values need to be
created in two measurement systems at the same time, inches and metric. For this purpose, a special
expression is introduced in the system - #DIM#. If this expression is used in any of the dimension lines
(strings), then a dimension value will appear instead of it in the drawing, which will be multiplied by the
alternative scale factor.
To follow the example on the right, set the «Alternative scale» to «Millimeters/Inches»
and enter the following text in the «Text|After» field: [#DIM#%%119].
The “Text” group of parameters allows defining the text that will be displayed before or after the dimension
value of an alternative dimension. Such strings can be entered manually or substituted by numerical or
text variables. You can familiarize yourself with this capability in detail by reading the description of the
counterpart parameter in the “String” section. If no parameter values are set in this group, then those are
taken from the “Alternative dimensions” tab of the “Customize|Status…” command.
The “Tolerance” group of parameters allows defining tolerance zones (ranges) and value deviation limits of
alternative dimensions:
Text. This parameter defines the included members of the dimension value string of an alternative
dimension (the dimension value only, the dimension value with tolerance, etc.). A value can be selected
from the list. The “Default” setting means the appearance of an alternative dimension will be determined
by the “Text” parameter setting in the “Tolerance” section.
The tolerance zone is defined by the same-name parameter. The value deviation limits can be either defined
manually (in the respective input fields) or calculated automatically. The method of defining deviations is
controlled by the “Set Tolerance” parameter:
