Feature review · 30 September 2026
Sources & product scope
The comparison describes engineering workflows, not equal feature depth or licence entitlements. Row descriptions describe CivilGeniX; the other columns name documented equivalents or companion workflows. A named alternative does not imply every CGX subfeature is available. Check the vendor’s current edition, licensing and regional configuration.
Green identifies a documented capability. Gold identifies a module, extension or companion product. “Check availability” means the exact workflow was not established from the sources reviewed; it is not evidence of absence. “Not Available” is used only for the documented direct-IFC-export limitation in InfraWorks. Scripting APIs and AI-agent tools are assessed separately.
CivilGeniX scope
CGX remains in preview. This review uses the application’s 26.1.17 feature guides and release notes, plus the independently deployed Shared Viewer documentation through 30 September 2026. The new comparison includes point clouds, DEM imports, advanced grading, rail, superelevation, articulated vehicle studies, drawing data bands, attributes, review, linked projects and browser sharing.
- Grading includes simple concave and curved boundaries, internal features, level regions and vertical/battered steps. Terrain reduction and estimated point-cloud ground filtering require review against source quality and project tolerances. Direct point-cloud publication to the Shared Viewer is not included; derived TINs follow surface workflows.
- Road superelevation supports preliminary calculations and editable schedules. Verified agency criteria, alternate pivots and advanced rollover handling remain separate work. Rail and electrification tools provide geometric modelling and checks, not a certified operator, electrical or structural design package.
- Swept paths support forward low-speed rigid and passive articulated vehicles. Reversing, active rear steering and certified tracking envelopes are not claimed. Traffic, flood, culvert and sight-distance tools support engineering screening. SWMM and EPANET results depend on reviewed inputs and boundary conditions.
- Drawing Production includes reusable details/title blocks, dynamic attributes, data bands, tables, review actions, PDF/print and editable CAD/XREF packages. Linked-project masters coordinate source-specific sheets; they are not full streamed model editing across all linked sites.
- Worksharing exchanges checked-in changes between local copies over encrypted LAN/VPN connections. It does not stream live cursors or simultaneous keystrokes. Reviewed packages remain a separate transfer workflow.
- Shared Viewer is read-only and publishes selected model content, including available road/network profiles and construction schedules. Recipients use a link and phrase without a CGX installation or account. Shares currently expire after 14 days; the prepared package limit is 512 MiB. Fragments streaming, LOD and bounded caching help manage resources, but capacity depends on the model, browser and device. Drawings and desktop editing are not included.
- Regional references and source-derived vehicle profiles are configurable aids, not blanket standards compliance. Machine-control output comprises reviewed interchange and setting-out data, not every proprietary controller format.
Official product sources
The linked official documentation supports each table entry. Some pages describe an earlier release where the documented workflow remains relevant. Companion products are named explicitly; asterisks identify the qualifications below. Vendor claims and product terminology belong to their respective owners.
Autodesk ecosystem — 4D construction
Civil 3D — APIs and Dynamo
Scripting and APIs are compared separately from scoped AI-agent authoring; one does not imply the other.
Civil 3D / AutoCAD — drawing attributes
Civil 3D — profile data bands
Civil 3D — DEMs and point-cloud terrain
Civil 3D - collaboration
Civil 3D - context and GIS
Civil 3D - design and drawing production
Civil 3D - hydraulic analysis
Civil 3D - drive-through visualisation
Civil 3D - IFC
Civil 3D - networks, properties and reports
Civil 3D — point groups and object tables
Civil 3D / AutoCAD — sheet publishing
Civil 3D — rail geometry
Autodesk Docs — file review
Autodesk Docs is a companion review service. Its approval workflow differs from CGX live-sheet markup and action tracking.
Civil 3D — sight-distance checks
Civil 3D — superelevation
Civil 3D - terrain and grading
Civil 3D - swept paths
Civil 3D — browser sharing
Shared Views supports browser review without Civil 3D installed. This does not establish parity with CGX road driving, 4D playback or engineering profile controls. Viewing does not require an Autodesk account; commenting does.
Civil 3D / AutoCAD — multiple model views
Autodesk ecosystem — pressure hydraulics
InfoWater Pro is a separate Autodesk hydraulic application built on ArcGIS Pro. Its listing is an ecosystem alternative, not a built-in Civil 3D or InfraWorks solver or a claim of direct model transfer.
InfraWorks - analysis and simulation
InfraWorks — 3D asset libraries
InfraWorks — point clouds and terrain
InfraWorks - context and visualisation
InfraWorks - direct IFC export
InfraWorks - roads and connected workflows
InfraWorks — superelevation
InfraWorks — browser sharing
Shared Views and comments are documented. The table does not claim the same action-closeout, drive, construction or vertical-profile experience as CGX.
Bentley ecosystem — iTwin developer platform
The iTwin platform supports separate integration applications. The table does not imply native AI-agent command access inside OpenRoads.
OpenRoads Designer - published scope
* iTwin is a companion review platform. Browser sharing is documented; the CGX-specific combination of road driving, 4D and profile controls is not implied.
Bentley ecosystem — rail electrification
Bentley ecosystem — rail design
OpenRail Designer is a separate product, not a blanket claim for the OpenRoads Designer licence.
Bentley MicroStation platform — multiple views
Bentley ecosystem - pressure hydraulics
12d Model - road design
12d Model - base modelling
12d Model - BIM
* 12d states that IFC BIM is included for customers on subscription or annual maintenance. This is reflected as an included capability, rather than a separate paid BIM module.
12d ecosystem — collaboration and drawing management
12d Model — drainage and drawing outputs
12d Model — dynamic hydraulics
12d Model - modules and options
12d Model — rail design
12d — model viewing
12d documents a viewer for customers and non-customers. The reviewed page does not establish browser delivery or the same interactive profile and playback capabilities; browser equivalence is left unconfirmed.
12d Model — visualisation
Visuals and attribution
Product captures are supplied CivilGeniX demonstrations, with source/provider attribution retained in the images. The Shared Viewer preview is a screenshot, not a publicly accessible project link. The triangulated landscape and connected-model nucleus are illustrative graphics, not survey or analysis data.
