HAMMER CONNECT internally keeps track of elements using a read-only ID property. In addition to this, users can and should identify elements using labels. The labels are purely for display and not used for data base management or hydraulic calculations. For the past several versions of the program, the models ran even if they contained duplicate or blank labels. On some occasions, however, duplicate labels could cause confusion (e.g. picking the wrong instance of an element in setting up a control). The Duplicate Labels query is a tool to find duplicate or blank labels.

The Duplicate Labels query is accessed through View > Network Navigator > Queries - Predefined > Input > Duplicate Labels.

This opens a dialog where the user can control the behavior of the query.

The element type parameter enables the user to search for duplicate queries across all elements or within a specific type of element.

Spot elevations are not included as a choice because duplicate spot elevations are not usually problematic.

The second choice in the dialog enables the user to control whether blank labels should be considered as duplicates.

The defaults for these parameters are to consider all elements and blank labels should be considered.

The query returns a list of elements with duplicate labels with their ID and Type. The user can highlight those elements in the drawing, zoom to individual elements and modify them as desired.
