Any feature marked with an asterisk (*) requires a database update to database version 2026.1 in order to access the feature. It is advisable to always update to the latest version of the database as it is easier for you to keep track of the various versions and ensures that any software patches are only applied to the applicable database versions.
Cloud capabilities
This release of InfoWorks ICM builds upon the cloud integration that started in version 2024.0. Learn more here.
Autodesk InfoWorks ICM Flood
InfoWorks ICM Flood is a new Autodesk product that uses ICM's hydrological and hydraulic modelling to provide event-based forecasting and risk assessment for networks that consist of up to 1000 nodes. InfoWorks ICM Flood can only be used with a Flood licence; you cannot use a Standard or Ultimate licence to access it. See Autodesk Licences for further information about Flood licences, and the ICM features and functions that are available with this type of licence.
If you are new to ICM, you may find it useful to view our on-demand training or use our Tutorials to help get you started.
Autodesk ICMLive Operator Client for InfoWorks ICM Flood
Autodesk ICMLive Operator Client is installed with Autodesk InfoWorks ICM Flood as part of the ICMLive system.
ICM Flood users with access to a manifest deployment deployed by an ICM Ultimate user, can use the Operator Client for example, to view areas of interest defined in the manifests, see a visual summary of any alerts, and analyse the results of live runs.
See ICMLive and ICMLive Design Workflow for details about an ICMLive system.
See the ICMLive Operator Client help for details about using the software.
Autodesk InfoWorks ICM Standard rebranded as InfoWorks ICM Sewer
The Autodesk product InfoWorks ICM Standard is rebranded as InfoWorks ICM Sewer.
The Sewer product still uses a Standard licence and all functionality that was available in ICM Standard is still available in ICM Sewer. See Autodesk Licences for details.
The Autodesk ICMLive Operator Client is also installed with ICM Sewer as part of the ICMLive system. You do not need an Autodesk licence to use it, but you will need an Autodesk account. See the ICMLive Operator Client help for further information.
Ruby scripts as database items
Previously, you could only use a Ruby script file in InfoWorks ICM that was created externally, and run either using the Run Ruby script option in the Network menu or by including the file in a customs action.
These options are still available but now you can also add a Ruby script as a
database item (
), and use the new
Ruby script editor to add Ruby script code, view or edit an existing Ruby script, validate its syntax and run the script in the current network in the
GeoPlan. You can also import an external Ruby script (RB) file as a Ruby script database item, and export the item if required. See
Ruby Script for details about this new item, and the various methods that can be used to run it.
The following video provides an example of using a Ruby script and highlights the benefits of using it as a database item rather than as an external file:
Including a Ruby script as a database item in a Custom action
As a Ruby Script is now available as a database item, it can be included in the Select object to apply for this dropbox in the Custom actions dialog. The alternative method of browsing for an external Ruby script in the or select a Ruby script to be run field is still available, as is the restriction that you can either specify a database item or an external Ruby script but not both. See Customs Actions for further information.
Additional network objects for Subgrid Sampling
As Subgrid Sampling - a Technical Preview feature in version 2026.0 - is still being developed, we have expanded the supported items that can be used with it to include the following network objects:
- River Reach - Bank Flows, when the river bank is connected to a 2D zone.
- Inline banks, when acting as a 1D-2D link.
See Using Subgrid Sampling for further information.
If you try our Subgrid Sampling Tech Preview feature, we would really appreciate your feedback before it's officially released.

Display improvement for flow in SWMM nodes
To improve the display of flow in a SWMM network, the precision for a node's Baseline inflow, Base flow, and Base flow for Additional DWF properties has increased from 3 to 5 when using metric (native) units. See Units Key for details of the precision adjustment for Flow (Q) when using other units.
Importing InfoSWMM Stage-Flow outfalls to SWMM networks
Previously, the import of outfalls of type Stage-Flow, from an InfoSWMM network to an ICM SWMM network, would fail as these type of outfalls are not supported by EPA-SWMM. Now they can now be imported to InfoWorks ICM as SWMM nodes with a Free type of output. A message is included in the import log that indicates which imported objects this conversion applies to. See the description of [OUTFALLS] in SWMM5 Conversion - Nodes (SWMM) for further information.
Importing InfoSWMM rating curve outlets to SWMM networks
Previously, the import of outlets with a Tabular Inflow-Outflow type of rating curve, from an InfoSWMM network to an ICM SWMM network, would fail as these type of outlets are not supported by EPA-SWMM. Now they can now be imported to InfoWorks ICM as Outlet types of links with Functional/Depth types of Rating curves. A message is included in the import log that indicates which imported objects this conversion applies to. See the description of [OUTLETS] in SWMM5 Conversion - Links (SWMM) for further information.
