The Model Data > Model Tools > Renumber Model function is used to renumber the model. The following Model Renumbering box will appear:
•The direction in which the numbers will increase can be chosen.
•The Selection only tick box can be ticked if only a selection of the model should be renumbered.
•The Only renumber empty codes tick box can be ticked if only link numbers with empty Link_Codes should be renumbered. You can e.g. delete the Link_Codes of a certain part of the network and then renumber only that part of the network.
•The Renumber button can be clicked to start the renumbering process. All the data related to the model elements, such as roughness coefficients, user data, elevations, outputs, etc., are retained. Only the numbers of the model elements are changed.
