To run this script
Select Script → Schematic → TurnON_Element_Display from the Menus.
Or in Version 13 or higher you can run the utility directly from this page using this button.
This is a simple script to turn on schematic element display for model names and IDs. You would use this if you had turned these off.
Below is an example with the mode names and IDs not displayed:
Below is the display after the script is run.
Note: you will have to redraw the schematic (zoom in our out) to redraw to see the change.
There are two accompanying scripts, one will turn the display off and the other will toggle the display (turn on if they are off or turn off if they are on).
