Demonstration video: Stormwater network design and analysis in Civil 3D with iDAS

We've released a new demo video that showcases a complete workflow for designing, analysing, and reporting on stormwater pipe networks using Autodesk Civil 3D and Devotech iDAS on a typical urban project.

Starting with a project overview, the video demonstrates how to quickly convert existing polylines into a pipe network, refine the model by breaking pipes at structures, correcting pipe directions, swapping multiple pipes and structures, and splitting pipes at specified intervals.

The workflow then moves into design tasks, including creating longitudinal sections, adjusting pipe elevations, and automatically delineating catchments and flow paths. You'll also see how to configure catchment properties and prepare the network for hydraulic analysis.

Once the model is ready, the video covers network analysis, automatic pipe sizing, and a review of key hydraulic results, including graphs, the Energy Grade Line (EGL), and the Hydraulic Grade Line (HGL). The model is then updated in Civil 3D and reanalysed to demonstrate the dynamic connection between Civil 3D and the analytical engine.

Finally, the video shows how to generate reports, calculate quantities, and run the analysis of a network with a detention pond.
