Part Labels and Annotation

You should see that all the parts you have placed have both a unique reference and a value. A

unique and sequential annotation is assigned to components as you place them on the

schematic, although you can re-annotate manually if you need to.

You have full control over the position and visibility of part labels – you can change the values,

move the position or hide information that you feel is unnecessary. The discussion below

details how to manipulate part labels on a per component basis.

If you zoom in on any resistor you have placed you will see that Proteus has labelled it with a

unique Reference (e.g. ‘R1) and also with a Value (e.g. ‘10k’). You can edit both these fields

and their visibility via the Edit Component dialogue form. Launch this dialogue form now by

double clicking the left mouse button over the resistor (or using one of the alternative methods

discussed previously).

The Edit Component dialogue form

From the resulting dialogue form you can edit both the part name reference and, in this case,

the resistance. Of more interest to us however, is the visibility options (highlighted in the above

screenshot). It can be useful, particularly in densely populated schematics to hide some details

displayed beside the parts – the tradeoff being that you would then need to edit the part as

above to see its reference and value.

At this stage it is worthwhile familiarising yourself with editing components and hiding and

showing references and values.

Some caution is required when changing part references in this manner. If, for example, you

change ‘R1’ to be ‘R2’ then you will have two parts with the same reference on the schematic.
