Solution Details

Special Strings Display

While string objects can be used to place user-defined text on the current PCB layer, it is not only user-defined text that can be placed. To assist in producing documentation, the concept of special strings is used. These act as placeholders for design, system or project information that is to be displayed on the PCB at the time of output generation.

The .Designator special string allows a secondary designator to be placed within a Footprint which can display the actual designator when the value is converted.

 

If you are seeing .Designator overlaid on your additional designators, this special string is in use, but the option to display the special string overlay values on screen is enabled, to enable or disable this setting do the following:

 

Within your PCB Editor access the View Configuration panel, if it is not visible you can access it from the menu command View ► Panels ► View Configuration or from the Panels button in the lower right of your workspace Panels ► View Configuration

From the View Configuration panel, click on the View Options tab

Scroll down on the View Options tab to the Additional Options section, and review the option for Special Strings and click to disable.  Once disabled the option will lose its highlight indicating it is disabled, you should then be able to see that the .Designator strings no longer have the .Designator text overlaid on the converted value
