This command is available from an Assembly document only.
Named the rule.
With the Add button, provide a Function.
Possibility to use a Filter document.
Select a cell in the Substitution column to specify a family, code and/or drivers that will be used as substitution.
| 
 | Right click on an existing substitution rule from the entities tree give access to the following commands: 
 | 
| 
 | - Global substitution has priority over rules. You must remove a global substitution so that rule is taken into account. - A rule could be used only if the generic document references a function document. This allows to not to unnecessarily fill the list of possible families with families that could be candidates. | 
Available options:
Filter:
| 
 | Filter allows to apply a substitution only to a specific type of components that reference the same function document. For example, with component containing screws of different types, we can apply a substitution rule for countersinking head screws only. Without filter, all screws would be substituted.
