StruBIM Box Culverts

New method for connecting applications to the BIMserver.center platform

The mode of communication between Open BIM applications and the BIMserver.center collaborative work platform has changed. In previous versions, the applications used the "BIMserver.center Sync" tool to upload and download the files of the contributions associated with the project from the platform. This tool was downloaded from the BIMserver.center platform or installed together with the installation of the platform applications if users so desired.

From version 2024.a onwards, applications are now able to work directly with BIMserver.center without an intermediary. That is, without the need for the "BIMserver.center Sync" tool.

This modification will improve the performance and efficiency of Open BIM applications significantly. By removing this dependency, the applications have more autonomy and the waiting times for communication between BIMserver.center Sync and the program have been considerably reduced. The process of downloading contributions has also been optimised, as users no longer need to obtain the entire content of a project from BIMserver.center in order to work, but only the contributions to be read.

The way of authenticating a BIMserver.center user in the applications has also been modified. Now, this process is carried out within the BIMserver.center web platform. To do this, the application with which the user is working will run the user's default browser when the "Login" button is pressed. When the credentials are entered, or after opening the browser if the user is already connected to the platform, an authorisation page will be displayed. This page details the resources the application is requesting access to and two buttons for granting or denying this access.

The authorisation must be carried out for each application. Once access has been granted, it is saved for the next time the program is run and there is no need to perform this process again for that application.

As well as performance improvements, changes have been made to the user interface of the Open BIM applications regarding the connection to BIMserver.center.

  • The "Connect to BIMserver.center" window now includes a "Configuration" button. Clicking it launches a menu from which you can edit the "File directory stored in local cache". This is the path where the files that make up the contributions will be downloaded when working with them from the applications. In previous versions, this location could be selected from the BIMserver.center Sync tool.
  • The appearance of the "Project selection" window has been modified.
  • In the "Select project" list, the "View only my projects" option has been added to show only the projects where the connected BIMserver.center user is the owner. Icons have also been included for the "Type of project" column in order to make it easier to identify them. The detailed data of a project now shows the image of each contribution, the description and the tags.
  • The "Review new contributions" and "Review updated contributions" options have been added to the "Create new project" window.
  • The list for selecting contributions ("Import BIM models") now includes the images of the contributions and the tags. The name of the contribution will be displayed in blue to indicate that the owner is the logged-in user.
  • When sharing a contribution or selecting contributions during the process of linking to a BIMserver.center project, a progress window will appear during the upload or download process.

To work in BIMserver.center with versions of Open BIM applications prior to 2024.a, users must continue to use the BIMserver.center Sync tool. This is still available for download from the platform and was included in the installation packages of the CYPE Open BIM applications prior to 2024.a.

Application name change and download at BIMserver.center

Version 2023.e was released on 19 January 2023. As of 3 February 2023, the "Box culverts" program has been renamed "StruBIM Box Culverts" in all of its installation languages and is also available for download from the BIMserver.center platform.

Connection with BIMserver.center

In version 2023.e, the Box culverts program has been connected to the BIMserver.center platform.

The top toolbar includes the "BIMserver.center" menu that contains the "Update" and "Share" options.


When the job is not connected to a project, it can be connected to a BIMserver.center project (new or existing) via “Update”. If the job is already connected to a project, users can access the management panel of the files to be included as links via "Update".


When using the “Share” option, the program exports the following to BIMserver.center:

  • Geometry of the structure
  • Reinforcement in GLTF format
  • Reports in PDF format
  • Drawings
  • Reinforcement for StruBIM Rebar

Font size

The "Font size" option has been added to the general configuration menu of the applications. This tool allows users to increase or decrease the basic size of the font used in the user interface of the programs. Thanks to this implementation, the accessibility of the applications has been improved while also ensuring the correct visibility of the content on devices with different screen resolutions.

To enter a "Basic size" the "Set custom font size" option must be checked. The size users can enter is the application's basic font size. Any other font sizes that may exist in the program's interface will be automatically modified proportionally according to the change in the basic size.

It is important to note that, as this is a common parameter, its modification will affect all installed CYPE tools.
