✅ – Generate editable tables and summaries for permit submissions or internal reviews.

✅ – Quickly calculate peak runoff using rainfall intensity, runoff coefficients, and time of concentration.

✅ – Compared to high-end suites like Civil 3D + StormCAD, RainCAD offers a lean, cost-effective alternative for small to mid-sized firms.

✅ – No need to export/import geometries to separate hydrology software. Work with catchments, gutters, and pipes right on your drawing.

✅ – Especially helpful for Canadian projects where both languages are required.

If you work in civil engineering, land development, or transportation design, you’ve likely faced the challenge of estimating stormwater runoff and designing drainage systems quickly. (a plugin for AutoCAD/BricsCAD) streamlines that process directly inside your CAD environment.

Here’s why RainCAD 2020 remains a useful choice for many designers:
