Product 01
InfraFlow
Gravity Engine
A production engine for gravity sewer networks inside Autodesk Civil 3D.
Move from unstructured drawing annotations to buildable, reviewable Civil 3D networks through one deliberate workflow. Extract, clean, build, connect and validate—without leaving your local environment.
Windows x64Offline licensingCSV + DWG workflows
InfraFlowBuild complete networks
Create Civil 3D structures, pipes, alignments and profiles from a reviewed CSV—or build directly from the source drawing.
Validate before delivery
Run read-only slope and cover checks, review build summaries, and catch missing parts or invalid rows without changing the model.
One connected workflow
From source drawing
to a checked network.
Gravity Engine keeps the decisions visible. Each stage gives your team a review point before the next production step begins.
Try the workflowPrepare
Confirm labels, layers, geometry and Civil 3D styles.
Extract
Center labels, read the drawing and export structured data.
Review
Check names, rims, inverts, diameters and connections.
Build
Generate the main network, alignments and profiles.
Connect
Add lateral structures and connected pipes.
Validate
Review slope, cover and delivery-readiness.
Download & test
Start with a real workflow.
Install Gravity Engine, activate the automatic seven-day trial, and use the prepared drawings to run your first extraction and network build.
