The Delete a Structure option allows you to delete a structure and merge the connecting pipes. Then all data associated with that structure and those pipes will be updated accordingly.
Upon selecting this option, the following window will appear:
Enter the structure number you wish to delete in the "Structure Number" field. You can manually enter the structure number or use the drop-down list.
Select the pipes to be merged from the upstream and downstream pipe drop-down menus.
Mark the "Delete Structure from Structure Inventory after Merge" box if you want the structure permanently deleted from the Structure Inventory module.
Note: This box will not be enabled if the structure connects other pipes.
