Update history​

CYPE 3D

Improved consultation of U.L.S. checks

As of previous versions Metal 3D and the integrated 3D structures of CYPECAD generate detailed ultimate limit state check reports for steel (rolled, welded and cold-formed), aluminium and timber bars (Analysis > U.L.S. checks > select a bar). To identify the checks that fail or consult a specific check, users must run through the entire report.

Now, as of the 2013.k version (as has been done for columns and beams in CYPECAD), “Metal 3D” and “Integrated 3D structures of CYPECAD” include a detailed check and specific check for each U.L.S. check, which helps to speed up the verification procedure.

The top-half of the dialogue box that appears when users select the U.L.S. checks option from the Analysis menu, displays a table containing a list of all the checks that have been carried out. Users select the check to be consulted, which is then displayed in more detail in the bottom-half of the screen.

This dialogue box has the same properties as the dialogue box that appears when using the concrete beam editor, explained in detail, in the section on the Advanced beam editor of CYPECAD of this webpage.

New predefined section series

In version 2024.b, the following predefined section series have been implemented:

  • NHBC UK Timber
    Timber sections.

  • SYS (Thai Standard)
    Steel sections for Thailand.

Warning for non-rectangular braced frames

In versions prior to 2024.b, if the braced frame was not rectangular, a warning message was displayed and the job could not be analysed. In the help text on the analysis of tie rods, the method’s validity conditions are listed. Among the conditions, the following is mentioned:

"The diagonal forms part of a braced frame framing the four edges, or three, if the stiffening bars reach two exterior fixities. Additionally, each panel must form a rectangle (the four internal angles being right angles)."

As of version 2024.b, the warning indicating that the braced frame is not rectangular is still displayed, but the job is not prevented from being analysed. The aim is to let users analyse structures even if the frames are not rectangular, but a warning is displayed. When the frames are not rectangular due to slight variations in their angles, the result may be acceptable depending on the structure. 

However, if there are very deformed frames, the analysis is still blocked due to this warning. This situation will occur when the cut-off point between the tie rods is further from the midpoint than 10% of the tie rod length, or when the difference in tie rods is greater than 20%.

Implementation. NSRM-2021 (City of Managua - Nicaragua)

Norma sismorresistente para la ciudad de Managua (2021)

Implemented in CYPECAD and CYPE 3D.

Furthermore, the "Limit drift between floors due to seismic action" has been implemented in CYPECAD for this code. In version 2023.e, this limit was implemented for other seismic codes that were already in the program in that version. More information on the limit drift between floors due to seismic action can be found in this new feature.

Implementation. ANSI/AISC 360-22 (LRFD)

"Specification for Structural Steel Buildings" (2022).

Implemented in:

  • CYPECAD and CYPE 3D for analysing and checking rolled and reinforced steel sections.
  • CYPE Connect and StruBIM Steel for analysing and checking steel connections.

Improvements in the connection to BIMserver.center

Version 2024.b includes the following improvements and corrections to the connection of applications to the BIMserver.center platform:

  • After sharing a contribution, there is a delay before it becomes available in the BIMserver.center project. This could result in another application not having immediate access, even if the export was made from the same computer. Now applications can read contributions from the "File directory stored in local cache" before they are accessible in BIMserver.center.

  • It is now possible to export a contribution without an internet connection. When this occurs, a confirmation dialogue box will appear to inform users that if the contribution is exported, it cannot be shared in the BIMserver.center project. The contribution can be read in another application as long as it is on the same computer and linked to the same project. However, for the contribution to be available on the platform, users will need to "Share" it again with an internet connection.

  • The uploading process has been improved to allow larger files to be included.

  • An error that did not allow users to connect to the platform when the "AppData" system folder was not accessible has been fixed.

  • An error that showed the user as logged in when the session had already expired has been fixed.

  • The warning messages displayed when there is a problem in the communication with BIMserver.center have been improved.

  • Now, when creating a new project, the same default fields are used as in the BIMserver.center website.

Links to the BIMserver.center platform

From the BIMserver.center project information window (displayed by clicking on the project name shown in the project information bar - upper right part of the application window) you can access the project page of the BIMserver.center platform via a link that has been inserted in the text indicating the project name.

Likewise, from the information window about the project contributions ("Contributions" option in the project information window), users can access the page of each contribution in the BIMserver.center platform. These links are inserted in the texts indicating the name of each contribution.

Notifications on the project status

The status information bar of the BIMserver.center project is located at the top right of the window of the programs included in the Open BIM workflow. This bar has been available in the applications since version 2022.e and shows a warning icon when there is a problem with the connection to the project, as well as other things. Now, in version 2024.b, users can obtain more information about the warning by hovering the mouse cursor over the icon.

Creating BIMserver.center Corporate projects

As of version 2024.b, users can create projects associated with a "BIMserver.center Corporate" account from all CYPE applications included in the Open BIM workflow. To do this, the "Owner" field has been added to the window for creating a new project. This is a drop-down menu that includes, as one of the available options, the logged-in BIMserver.center user name along with the "BIMserver.center Corporate" accounts to which it has access. When selecting the user name as the owner, the project will be associated with this personal account, as was the case in previous versions. On the other hand, if a BIMserver.center Corporate account is selected, the project will be associated with that account.

Clear cache

The "Clear cache" button has been added to the CYPE applications included in the Open BIM workflow in the "Configuration" dialogue box that opens with the following sequence of commands: Select any of the options in the "BIMserver.center" tool group > "Configuration" option in the dialogue box that appears. When clicking on "Clear cache", the following options are displayed:

  • Projects
    Deletes projects, contributions and documents downloaded from the platform that are in the "File directory stored in local cache".

  • Sessions
    Deletes the data of any active sessions. This action will require applications to be re-authorised to access BIMserver.center.

  • Log files
    Deletes transaction logging from applications with BIMserver.center.

Long access paths

In previous versions, file paths used by applications were limited to a maximum length of 256 characters. This restriction is not specific to CYPE tools but is set by default in the Windows file system. As of version 2024.b, CYPE applications can bypass the restriction and allow the use of an extended path length for a maximum total path length of 10,000 characters. This eliminates the problems caused by the default limit and allows users to work with long access paths.

This improvement is particularly useful when working on projects with a complex directory structure or with long file names. By allowing longer paths, CYPE applications offer greater flexibility in file organisation.

Classic menu of CYPE programs

As of version 2024.b, the classic menu of CYPE programs has a downloadable version available from the BIMserver.center platform Store.

This new classic menu downloaded from BIMserver.center includes the same applications and layout as the version available from the download area of the CYPE website, but with some differences.

When installing the BIMserver.center menu, only those applications that are not available for individual download in BIMserver.center will be included in the installation. The other applications in the BIMserver.center menu (those that can be downloaded individually from the BIMserver.center Store) can be downloaded and installed when they are opened for the first time from this new menu.
