InfraGrid3D

InfraGrid 3D is a browser-based civil engineering design platform for roads and utilities. It lets teams model carriageways, kerbs, drainage, duct banks and public lighting to construction detail without a Civil 3D install, and export the same model to Revit, IFC or DXF.

Key facts

What is InfraGrid3D?

Design roads, drainage and underground services in the browser and push the same coordinated model into Revit, IFC or DXF.

Who is InfraGrid3D best for?

Civil engineering teams, infrastructure and highways designers, utilities/drainage engineers, Revit and BIM coordinators working on data centres, industrial sites, housing, public realm and highways

What are its main limitations?

Listed as a public beta
Pricing page returns a 404, so no published pricing
Revit workflow requires downloading and installing a Windows Revit add-in (Revit 2024–2027)

Limitations are based on product materials or editorial synthesis; confirm on the official site.

Key features

✓Browser-based modelling of carriageways, kerbs, junctions, drainage, duct banks and public lighting
✓Duct bank routing with configurable number of ducts, depth, cover and bend radii, routed by clicking points
✓Live long sections and cross-sections generated from the model, including imported IFC and survey lines
✓Live clash detection against imported IFC (foundations, structures and other services)
✓Export to IFC, Revit, DXF and PDF, including plans, sections and long sections
✓Revit add-in: export JSON from the browser and import as native pipes, walls, floors and typed DirectShapes with re-import replacement
✓Point cloud / survey import (LAS, LAZ) and 2D GPR line import as 3D
✓InfraGrid AI Assistant that executes changes through the same tools, with multi-step runs and undo/checkpoints

Use cases

→Set out road corridors, junctions, radii and kerb build-up before construction
→Route storm and foul drainage, watermain and HV/LV banks with chambers at bends
→Check new routes against existing foundations, structures and services via IFC clash checks
→Produce long sections and cross-sections that update as the model is edited
→Export road, service and chamber geometry into Revit for coordination with architectural and structural models
→Place public lighting columns with laterals connected to the lighting conduit

Pros

+Runs in the browser with no Civil 3D seat required
+Single model drives roads, services, sections and exports
+Exports to IFC, Revit, DXF and PDF for coordination
+AI Assistant performs real modelling actions rather than producing text, with reversible multi-step runs
+Supports point cloud (LAS/LAZ), survey and GPR survey import

Cons

−Listed as a public beta
−Pricing page returns a 404, so no published pricing
−Revit workflow requires downloading and installing a Windows Revit add-in (Revit 2024–2027)

Frequently asked questions

What is InfraGrid 3D?

A browser-based civil engineering design platform for roads and utilities. You model carriageways, kerbs, drainage, duct banks and public lighting to construction detail and export the same model to Revit, IFC or DXF.

Do I need Civil 3D to use InfraGrid?

No. The site states you can work in the browser without a Civil 3D install, and the design can continue in Revit, Civil 3D or AutoCAD after export.

Can I export to Revit?

Yes. Download the InfraGrid Revit add-in (Revit 2024–2027, ZIP, run Setup.exe, no administrator rights), then Export → Export to Revit… in the browser studio and use InfraGrid → Import in Revit. Geometry lands as native pipes, walls, floors and typed DirectShapes.

What does the InfraGrid AI Assistant do?

It executes modelling commands through the same InfraGrid tools as the ribbon — for example placing staggered street lights, running storm and foul pipes with chambers at bends, adding a bus lay-by, or cutting a cross-section. Actions are reversible with undo and checkpoints.

What file formats does InfraGrid support?

Export to IFC, Revit, DXF and PDF, plus JSON for the Revit workflow. Import includes IFC, LAS/LAZ point clouds and 2D GPR survey lines.

How much does InfraGrid 3D cost?

No pricing is published on the site — the pricing page currently returns a 404 error, so pricing details are not available.
