A reference designator uniquely identifies a component instance
in a PCB assembly. It typically consists of a letter and a number, where the
letter identifies the component type and the number identifies the instance. For
example, “R944” is Resistor 944.
CircuitWorks uses the reference designators from the ECAD system
if present. Otherwise,
CircuitWorks
assigns a temporary reference designator (Ref. Des.) to each instance of a
mechanical component. In either case, you can specify a
different reference designator.
When you open an IDX 3 file in CircuitWorks,
the software assigns the Ref. Des. that is also available in SOLIDWORKS when you
build the model. The Ref. Des. appears in the CircuitWorks tree with the instance
name. The same Ref. Des. appears in the SOLIDWORKS FeatureManager design tree
after you model the mechanical components in SOLIDWORKS.
You can also edit reference designators by clicking
a component instance in the CircuitWorks tree twice (slow double-click), typing a
new designator, and pressing Enter.
