Expression Builder Dialog

This dialog is launched from the Wire Diagram Settings page of the Options dialog. It enables the user to build expressions to define the connection information symbols.

Note: The user can specify the column width for each variable that is included in the expression. This will allow the text to be output in what appears to be columns, so that the variable values in the wiring diagram output lines up better. To continue to output a single text string expression as in previous versions, make sure the width value for each variable is 0.
SettingDescription

Use single column expression Enable this check box to automatically set the column widths to 0 and output the text as a single string expression. Disable this check box to specify the column widths in order to output the text in multiple columns.
