its frustrating when interrogating and amending the pipe network, when the pipes and chambers are not in the same order, the way it was presented in MicroDrainage gave a clear path with the final outfall pipe being at the bottom, not randomly placed somewhere based on what order you drew it, as you often chop and change the network through design progress. this worked for 20+ years.

Thank you for the suggestion and thanks to those who voted/commented.
The dendritic numbering system in MicroDrainage was limiting as it would prevent users from modelling bifurcation - it was also causing issues when renumbering the drainage system.
InfoDrianage has a flexible numbering system that defines the pipe by the upstream and downstream junctions - we believe that this enables a more sophisticated simulation and more complex arrangements to be implemented and we totally understand that users who have been used to dedritic numbering for years might find this frustrating but hopefully you will be able to get used to the flexible numbering system.
Would you please elaborate on what is it that you cannot achieve in InfoDrainage. You can still use a dedritic numbering system but manually - we might consider enabling users to automatically name their pipe systems using the dedritic numbering, if that solves the issue, please let us know. I will move this to Under Consideration.
