CYPE Connect Classic

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.

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.

Exporting in FBX format

Version 2023.a of all CYPE programs that have the "Print/Save the current view" tool (usually all programs that display graphic information in a window) allows any generated 3D model to be exported in FBX format. This is one of the most common and accepted formats among rendering software (Twinmotion, Enscape, Sketchup+Vray, among others).

Exportation in FBX format is found in the dialogue box that opens when selecting the "Print/Save the Current View" button in any of the programs that include this tool. This feature allows users to export any element that is visible in the current window at that moment in FBX format (as well as elements that have been imported from other programs).

General improvements

Version 2021.g of CYPE’s programs is a closing version of the 2021 version.

As well as the new features and improvements expressly indicated in each version of CYPE software, process optimisation involving internal updates for all our programs is normally included. In each revision, all programs are systematically checked and changes are made to improve their performance, therefore, we recommend that our users (in this case those of v.2021) always update their version to the latest one, regardless of the country for which they are using CYPE software or the language in which it is installed.

Prequalified connections in accordance with ANSI/AISC 358-10 and ANSI/AISC 341-10 (CYPE Connect Classic)

As occurs in CYPE 3D, as of the 2018.a version, CYPE-Connect includes the analysis, design and check of prequalified connections in accordance with ANSI/AISC 358-10 (Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications) and ANSI/AISC 341-10 (Seismic Provisions for Structural Steel Buildings).

Prequalified connections are applied to Special Moment Frames (SMF) and Intermediate Moment Frames (IMF) as indicated in the ANSI/AISC 341-10 code.

It is possible to define prequalified connections in projects in which the rolled and welded steel code: ANSI/AISC 360-10, has been selected.

For more information on which prequalified connections have been implemented, how beams interact at the same node, the checks that are carried out and drawing that are generated, please consult the relevant sections in the new features of CYPE 3D of this webpage.

Operation in CYPE-Connect

To calculate prequalified connections in CYPE-Connect, users must select the rolled steel code: ANSI/AISC 360-10, the connection in question must have the geometry corresponding to one of the implemented prequalified connection types, and the moment earthquake-resistant system option in the “Edit the geometry of the node” dialogue box must be activated with one of the available systems (SMF – Special Moment Frame, or IMF – Intermediate Moment Frame).

Even though no checks are carried out on cold-formed steel for prequalified connections, for internal operation purposes of the program, the selected cold-formed steel must be one CYPE-Connect considers to be compatible with the ANSI/AISC 360-10 code, such as “AISI S100-2007”.

As well as the earthquake-resistant code that is used, the following parameters must be defined:

  • The height of the higher floor
    It is defined in the dialogue box where the earthquake-resistant system is selected and is required to estimate the shear of the column and check the shear in the node panel.
  • Check as connection without lateral support in the direction which is transverse to the seismic frame
    To check the requirements of article “E3.4c” of the “ANSI/AISC 341-10” code, this option must be marked, which is also available in the dialogue where the earthquake-resistant system is selected.
  • Free span of the bar
    It is used to establish the moment at the face of the column. It is introduced in the “Edit node geometry” dialogue box (“Check” section).

Connections without stiffeners

In previous versions, connections fixed to column or beam flanges, welded or bolted, required web stiffeners.

As of the 2016.a version, these connections can be defined without stiffeners. This option is available only to check the connection. If the connection is re-designed, stiffeners will be provided. Users has the option to delete the designed stiffeners and check the connection without the stiffened web. Stiffeners associated with a moment reinforcement in the connection to the web of the main section are required and cannot be eliminated.

Types of welds

In versions earlier than the 2016.a version, the type of weld applied could not be edited. The welds are generally angle welds (except in connections with circular hollow sections and anchorage bolts).

As of the 2016.a version, the type of weld can be edited. Users can choose amongst:

  • Fillet weld
  • Full with complete penetration (simple bevel weld)
  • Full with complete penetration (double bevel weld)

The welds will be represented on the plans with their corresponding symbols.

Bolts

Thread dimensions and lengths have been updated for all bolt series. Bolt series A307 has been increased up to diameter 4.

Connections at an angle on plan

As of the 2015.f version, some types of welded and bolted I-section beam-beam and beam-column connections can be designed and checked in CYPE 3D and in CYPE-Connect when beams reach the web of the other beam, or to the flange or web of columns and are not at a right angle on plan.

The maximum permitted angle will depend on whether the connection can be executed (space available to place bolts) and on design standard limitations (effective weld angle).

Below are the types of connections for which this angle can be used (for both welded and bolted connections):

  • Beam – column flange moment connections
  • Beam – column web moment connections
  • Beam – column flange simple connection
  • Beam – Column web simple connection
  • Beam – beam simple connection

The connection details drawing includes an on-plan view, the angle of the beams with respect to the plane orthogonal to the surface connecting to the column or beam.

Connections with eccentricity between webs

As of the 2015.f version, welded and bolted I-section column-lintel connections designed and checked in CYPE 3D and CYPE-Connect, can have slightly eccentrically aligned webs. Both programs can design these connections whilst the projections of the webs of the column and lintel overlap in a plane perpendicular to that of the webs’.
