About Drainage Design and Analysis Tools for Civil 3D
Drainage design and analysis tools for Civil 3D provides drainage network design tools in Civil 3D, with an cloud-based analysis solution that is powered by InfoDrainage. These workflows do not require excessive use of external tools which allows for a smoother iteration between design and drainage analysis in a project. Sketch stormwater basins such as ponds along with your existing gravity network and run a thorough analysis on custom or historical rainfall data. Issues in the network are highlighted so they can be corrected before an analysis can be run.
