Thanks again to all those who voted, I am pleased to announce that the composite runoff coefficient calculations are now possible using land use polygons in InfoDrainage.

Please try the new land use and soil type objects in InfoDrainage and let us know how you get on. For details on how to utilise them for composite runoff coefficient, please see the following link (What's New in 2025.4):

How much of this feature request does this new update cover? https://www.autodesk.com/blogs/water/2024/11/15/land-use-and-soil-type-incorporated-into-sub-catchments-in-infodrainage-2025-4/

We use HydroCAD instead of InfoDrainage because it automates this.

Automating this process by allowing users to clip layers from Civil 3D (Soils, landuse, catchment areas) to create a composite curve number quickly would also be helpful

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

This is now under consideration for future development.
