Utilities Menu:

The Utilities menu provides various advanced editing tools and operating tools such as the Locate command to locate your elements graphically on your Map. Use the Merge Node and Switch Node commands to move and modify your data elements graphically. Manage the InfoWater Database. Additionally verify Connectivity issues and Recall deleted elements. Another very useful command available from the Utilities menu is the Change ID command that allows you to change InfoWater element IDs.

Click on any section for more information.

Locate - The Locate command is used to find a node/pipe/element by ID within an InfoWater project. This function is also available from the Model Explorer - Attribute Tab toolbar                         . See: Locate

Merge nodes - This command is used to combine two separate nodes into a single node.  The user is first asked to select a node to be deleted, then to select the node to represent the merged node.  Pipes connected to the two nodes will be reconfigured to the merged node location.  If the Auto Length Calculation is turned on, then the lengths for connecting pipes will be adjusted according to the new node location.

Switch Node - The Switch Node command is used to reassign a pipe(s) from one node to another.  For example, if pipes 45 and 75 are connected to node "A", but you want those pipes to be connected to node "B", use the switch node command to relocate the downstream node for those pipes from node "A" to node "B".  This command greatly facilitates having to redraw the geometry of pipes just because a downstream node of a pipe is desired at a different node.

Change ID - The Change ID command allows the user to change the InfoWater database identification for any element from one value to another (as long as the new value for that element is unique).  Merely select the Desired Element Type to change, type in the Old ID then the New ID.  Clicking Apply will change the ID for that element.  Click here to learn more.

Connectivity - The connectivity feature has many elements that assist the user in ensuring that connectivity is established prior to a model being run.  It is important to note that connectivity is required for InfoWater to run a hydraulic simulation.  Click here to learn more.

Network Review/Fix - The Network Review/Fix Tool is a comprehensive network drawing examination and correction application for use in constructing reliable, credible working models ready for analysis. It offers users functionality to quickly identify and correct network topology problems and data flaws that may arise from digitizing a model or building it using pre-existing GIS and CAD datasets. See: Network Review/Fix Tool

Database - The database feature allows the user to utilize database management from within InfoWater to find and correct database flaws or problems.  Click here to learn more.

Recall - The recall command (or Undelete) allows the user to recall a deleted pipe or node from the project database.  It is important to note that when a record is deleted from a database, it is only "marked" for deletion (unless the user has turned on the Auto Database Packing feature in the Project Preferences).  Click here to learn more.

Update DB from Map - This feature allows the user to recreate some or all of the project databases from the graphics in the InfoWater project from the project databases.  Click here to learn more.

Update Map from DB - This feature allows the user to regenerate the map graphics from the project database to ensure that the map view and the database contain the same data.  Click here to learn more.

Update Spatial Indexes - The Update Spatial Index command will help to speed up the map refresh in ArcMap. When there are tables joined to an InfoWater layer, ArcMap will not update the spatial indexes when those tables have been modified. The Update Spatial Indexes command will update the joined tables for an improved map refresh rate.
