The Silkscreen of my Altium PCB project only shows Reference Designators of components. I want to show component value or part number instead of the reference designator on the silkscreen. Is there a way to do that for all components on the PCB top layer instead of doing it individually for each component one by one?
It's not possible unless the value is stored in the component's
Comment section. So if you put the value as a
Parameter then you can't make them visible in the PCB design.
In the schematic design, put the values into the
Comment section for each component and update the PCB via Design -> Update PCB Document. After transferring the modifications to the PCB design, select all components and open PCB Inspector, then tick
Show Comment. That's the only way.
