A broken wire appears as a dashed black line with a red X in the middle. Broken wires occur for a variety of reasons, such as when you try to wire two objects with incompatible data types. Move the Wiring tool over a broken wire to display a tip strip that describes why the wire is broken. This information also appears in the Context Help window when you move the Wiring tool over a broken wire. Right-click the wire and select List Errors from the shortcut menu to display the Error list window. Click the Help button to display more information about why the wire is broken.

To correct the broken wire, you can delete it or you can right-click the wire and select from shortcut menu options such as Delete Wire Branch, Create Wire Branch, Remove Loose Ends, Clean Up Wire, Change to Control, Change to Indicator, Enable Indexing at Source, and Disable Indexing at Source. These options change depending on the reason for the broken wire.
