The Civil Infrastructure Technology Exchange (CITE) is a community where AECO professionals connect to exchange ideas, explore industry trends, and influence the future of civil design. Together, we foster a culture of curiosity, innovation, collaboration, and collective progress across the industry.
This CITE User Group panel features a head-to-head comparison between Civil 3D and Autodesk Water (InfoDrainage), highlighting how both toolsets handle storm network design, hydraulic analysis, and green infrastructure workflows.
Key Highlights & Insights
Civil 3D vs. InfoDrainage Synergy: While Civil 3D natively handles pipe layouts, profile creation, and drafting, InfoDrainage serves as an advanced design and analysis engine for dynamic SWMM-based hydraulic modeling. The tools work together in a complementary BIM workflow.
Green Stormwater Infrastructure (GSI): InfoDrainage simplifies modeling for complex sustainable systems—such as rain gardens, sand filters, infiltration trenches, and underground storage structures—connected directly to conveyance networks.
Poll & Community Feedback:
The vast majority of attendees rely on Civil 3D for daily drainage design, alongside widespread continued use of legacy/supplemental tools like SSA, HydroFlow, and custom spreadsheets.
Most users surveyed reported being early in their InfoDrainage journey ("bone dry" or "light drizzle"), signaling a strong opportunity for deeper workflow integration.
Comprehensive Water Ecosystem: Covers Autodesk’s broader water portfolio across planning, heavy civil design, build, and operations—spanning Civil 3D, InfoDrainage, ICM, Info360, and Tandem.

This session covers the next generation of drainage design and analysis tools integrated directly into Civil 3D, leveraging the InfoDrainage calculation engine for in-product hydraulic workflows.
Key Features & Drainage Objects
Analyze Drainage System: A native Civil 3D analysis command powered by the InfoDrainage engine. Runs SWIM-based dynamic wave calculations without requiring external software like SSA.
New Drainage Objects:
Ponds: Create simple ponds with custom side slopes and shelves, or generate detailed pond objects directly from surface contours. Extract feature lines for full grading control.
Underground Storage: Define chamber footprints, depth, and volume, with support for importing vendor storage tables (depth-vs-volume data).
Channels: Build channels using feature lines or alignments/profiles. Customize cross-sections via standard geometric shapes or directly attach Civil 3D assembly link codes.
Catchment & Runoff Updates: Added support for SCS, CPA SWMM, Santa Barbara, and Rational/Modified Rational runoff methods alongside updated Time of Concentration calculations.
Rainfall Management: Configure IDF curves, distribution-based rainfall, or custom time-increment rainfall data directly inside Civil 3D.
Outflow & Infiltration Controls: Define complex outlet structures including orifices, hydro-brakes, weirs, and bottom/side infiltration rates.
