Parent page: PCB Query Functions - Membership Checks

Summary

Returns all objects (parent and children) that are part of the specified union.

Syntax

InNamedUnion(UnionName : String) : Boolean/Boolean_String

Union names are automatically assigned, but can be renamed through using the PCB panel in Unions mode. As you define the Query expression, a pop-up list of all existing unions, by name, is presented.

Example Usage

InNamedUnion('Unions')
InNamedUnion('Unions') = True
InNamedUnion('Unions') = 'True'

Returns all objects (parent and children) that are part of the union whose name is Unions.

Not InNamedUnion('Unions 1')
InNamedUnion('Unions 1') = False
InNamedUnion('Unions 1') = 'False'

Returns all objects except objects (parent and children) that are part of the union whose name is Unions 1.

Tips

  1. The single quote characters (') at the start and end of the UnionName string are mandatory.
