Change subcatchment slope field to calculate correctly if non-numeric value used in Link Suffix.

When using InfoWorks ICM, if a network has a non-numeric link suffix in a conduit, the associated subcatchment slope field will not calculate. This results in a flat slope field and will affect run-off in simulations. Its not mentioned in the guidance/support (or could be anticipated by users) that using non numeric link suffix would result in this output. Please can ICM be amended to use a slope from conduit whatever the suffix?

This tends to affect users if they import networks direct from InfoAsset which uses a non-numeric suffix by default. Surely sister applications from same vendor should work seamlessly without users having to be aware of this issue?

    Thank you for the suggestion and thanks to those who voted.

    I agree with the importance of this suggestion and I will move this to 'Under Consideration' given that it is easy to implement.

    Will keep you updated here once we start making progress with it.
