CADWorx Plant I tab: Setup Size/Spec > Change Spec 
Command Line: CHANGESPEC
Changes the specification of the selected components. The software determines the change specification based on the size and type of the selected component. The Change Spec command has two modes either Automatic or Manual.
Automatic
Changes all the components on the selected line to the chosen specification automatically, depending on the following conditions.
The Automatic option only changes the specification assigned to the system until it reaches another
specification.
If Show optional components or Show all components in the Settings tab of the Spec View palette is turned on, then the following rules apply:
-
When the specification contains only one matching default component, then the software selects the default component.
-
When the specification contains no default and only one optional, then the software selects the optional component.
-
When multiple components match the component in the chosen specification, the component list displays both the matching non-optional and matching optional components.
Manual
Changes only the selected components to the chosen specification.
If Show optional components or Show all components in the Settings tab of the Spec View palette is turned on, then the following rules apply:
-
When the specification contains only one matching component in the chosen specification, then the software selects the default.
-
When the specification contains only one optional component in the chosen specification and no default component, then the software selects the optional component.
-
When the specification contains more than one matching component in the chosen specification, then the software provides you a list of the components.
If Show optional components or Show all components in the Settings tab of the Spec View palette is turned off, then the following rules apply:
-
When the specification contains only one matching component in the chosen specification, then the software selects the default.
-
When the specification contains one or more optional components in the chosen specification and no default component, CADWorx does not change the specification and displays an error message.
