July 2025 | Please read the following carefully, as the way you access and manage model data in the cloud has changed going forward. Your existing access is unaffected.
Previously, your team's cloud model data (i.e., collection of model databases and simulation results, referred to as a tenant) was stored in a single data hub'within your team. To access this data, a user required a suitable license (e.g., InfoWorks ICM) assigned in the team and all users had full write-access to the data.
Going forward, a data tenant is a project within a hub, and your team may have multiple hubs and multiple projects within each hub. Your existing data tenant has become a project within your original hub, with the project taking the same name as the hub, and all users with relevant licenses in the team have been added as members of this project with a role that gives them write access to the data.
For full details on this new hub and project administration system see About Administration.
The following sections summarize how the new system affects administrators and modelers respectively.
Administrators
A project administrator can control whether a user has write access to model data, or only read access, by assigning the user either the Model Editor or Model Reader role (see Roles for more on role assignment). A role must be assigned to access the data; users in a project with no role have no access.
From desktop version 2026.1 onwards, no license is required for read access (e.g., when using the new ICM Viewer). It is sufficient to invite the user to your project and grant them Model Reader role. Older desktop versions do not support unlicensed access.
A license is required for a user to have write-access to your data (and to run simulations) but this license does not need to be assigned to the user in your team. A user with a license assigned in a different team can work with data in your project if you add them as a member of the project and assign them the Model Editor role.
Modelers
If you use desktop version 2026.1 or earlier, the desktop experience is almost unchanged. To select a cloud database, you must first select from a list of what the UI describes as hubs but is now actually a list of projects. Because your old hub has become a project with the same name, this list will initially be unchanged. All projects that you are a member of will appear on this list, regardless of the hub or team to which the project belongs. To help interpret the entries in the list, the hub name is added in brackets after the project name.
You may be given only read access ("Model Reader" role) for some projects. Desktop versions prior to 2026.1 will display error messages if you attempt to save changes to data in a project to which you have only read access. From version 2026.1 onward, the desktop will show such data as "read-only" and will not offer choices that allow you to modify data.
Versions 2026.2 onward also provide an enhanced database selection dialog that allows you to select first a hub, then a project within that hub, and displays additional information about the team and region of the selected hub and whether access to the selected project would be read-only.
