The Show Line Connections tool shows the selected circuit colored by connection type, i.e. grounded vs. ungrounded connections. See illustration below.
This utility, initialized from the Circuit Tools dialog, launches the selection procedure (i.e. mouse pointer-finger) for user to select a circuit of interest.
For selected circuit, the connection indicators dialog is displayed and connection types are indicated by illustration. Note: Lines and cables in other circuits remain depicted in the normal view (i.e. Color by Part).
Grounded circuit connections are shown by Pink lines, with X marks showing at higher zoom levels (i.e. see inset).
Ungrounded circuit connections are shown by Green Lines, with rectangular boxes showing at higher zoom levels (i.e. see inset).
The user may then select [OK] to continue running utility and select another circuit, or select [Cancel] to exit the application and return to Circuit Tools dialog.
