This topic lists any bugs that have been fixed between versions 2025.3 and 2025.4 of InfoWorks ICM.
See Known Limitation and Issues for a list of limitations and any issues that we are aware of.
The fixes listed below are those that are viewed as likely to impact on users in an unexpected way, mainly changed simulation results, or differences in behaviour that might not be obvious.
Saving layer settings
A crash when attempting to save GeoPlan layer settings has been fixed.
Selection lists with SWMM networks
When dragging a selection list onto a GeoPlan for a SWMM network, there is no longer a dialog saying "Set link(s) branch ID to this selection list?". Branch IDs are not set.
Import of rainfall volume/depth from InfoSWMM
Rainfall volumes and depths are now converted correctly to intensity when importing from InfoSWMM to SWMM networks.
Effective rainfall
The effective rainfall (EFFRAIN) summary result is no longer reported as double what it should be in networks containing subcatchments that use ReFH runoff.
Download of results of cloud simulations
If the option not to accept local jobs is set in the local agent, the download of results from cloud simulations was silently failing. The agent event log incorrectly reported that the job had been refused because remote jobs are not accepted. The "Do not allow simulation on 'This computer'" setting now applies only to locally run simulations.
InfoSWMM import with missing DAT file
When a DAT file is missing in a model being imported from InfoSWMM, the missing file is now skipped instead of causing an internal error.
Additional symbols in GeoPlan themes
Additional symbols included in themes are now applied correctly to GeoPlans.
Working with runoff surfaces in scenarios
Attempting to rename a runoff surface differently in the base and in a scenario no longer provokes an error.
Buffer too small error
When the "IWRTRACECACHEGEN=2" setting in the ICM Agent has been used for running a simulation in a non-cloud database, attempting to graph results no longer gives an error "AsyncReadTrace - buffer too small".
Buildings results
An error "Network results polygon ... not found in Network" when opening the results of a simulation using buildings has been resolved. Simulations exhibiting this problem will need to be re-run.
Projections in MapXtreme GIS layers
Using the MapXtreme map control, the British National Grid EPSG 27700 projection and some others were not being detected correctly when adding GIS Layers. This has been rectified.
Crash when exporting to shapefile
A regression introduced in 2025.3 meant that exporting results from an older database version to shapefile was causing the software to crash. This has been fixed.
Simulations starting from states
Simulations were crashing when a run without a rainfall event uses an initial state from a run with a rainfall event, when using Green-Ampt, Horner, or CNSWMM runoff volumes. These simulations now fail cleanly with an error message.
Return period analysis "Produce Grid" button
A regression in the previous release meant that the "Produce Grid" button for RPA was enabled when it shouldn't have been, and crashed the software. This has been fixed.
InfoSWMM import of daily evaporation
Daily evaporation values are now converted correctly when importing from InfoSWMM to SWMM networks.
SWMM simulations
SWMM simulations using rainfall events containing multiple profiles and multiple subevents should no longer fail.
CSV Export
Exporting to CSV without the use of a selection list no longer converts all object IDs to upper case.
Error messages in SWMM simulations
Possible errors in rainfall data used in SWMM simulations were not always being reported in the RPT file. This has been rectified.
Copying commit history from SQL Server and Oracle databases
When copying networks from an SQL Server or Oracle database, commit history comments are now copied to the new database.
Long sections of SWMM results
When a pipe has a drop manhole, the Hydraulic Gradient Line (HGL) is now drawn correctly on long sections.
Vulnerabilities
The following vulnerabilities have been fixed:
CVE-2024-6197, CVE-2024-7264
See the Autodesk Trust Center for details about vulnerabilities in InfoWorks software.
