Update history​

CYPECAD

Updating the CYPE Menu applications

As of version 2024.f, the CYPE Menu tool (available on the BIMserver.centre platform Store) allows users to manage the updates of the applications it includes.

When accessing the CYPE Menu, the program checks whether there is a newer version of the installed applications and, if so, the "Update" option appears next to them.

The update process will download the application and, once completed, will start the installation.

Other improvements and corrections

CYPECAD version 2024.e includes the following improvements and corrections to the program for some specific cases:

  • The editing of project comments (General data > Project comments) has been improved. Previously, the description was plain text. As of version 2024.e, thanks to the new text editor, images can be included and the text can be formatted.

  • Now, when a column or a shear wall is moved in the "Column definition" tab, the foundation elements underneath it (pad footings or pile caps) are moved in unison, and this can be seen when selecting the "Beam definition" tab.

  • The "Stair options" and "Ramp options" have been improved. Users can now edit the "Specific weight of the fill".

  • The definition panel for the generic section of columns that appears when they are entered has been improved. The possibility to enter them by snapping a "DWG/DXF" template has been restored. This option was unintentionally lost due to a change made in previous versions.

  • The export of the positive reinforcement of in-situ joists and their 3D visualisation has been improved. The bends of these reinforcements are now displayed correctly. In previous versions, they were displayed as if they were the top reinforcement.

  • The export of footings affected by "Limits for polygonal footings" has been improved. Previously, they were exported with the original geometry, now the entered limits are taken into account.

  • The export of the reinforcement of caissons and their visualisation in 3D has been improved. Previously, if there was more than one in a pile cap, the reinforcement was not placed at the position of each caisson, but in the centre of the pile cap.

  • An error that occurred when importing a job with walls and beams, when no beam had all the necessary information for its import, has been fixed.

  • An error that occurred when accessing the panel to generate drawings has been fixed. This error could occur if there were defined metal section columns over a concrete column in the job. This error occurred unintentionally when fixing another error in a previous version.

  • The warning that used to appear when any beam overlapped with a foundation element has been removed. This warning prevented the job from being analysed. It is now only displayed if a centring or tie beam is not connected to a foundation element and overlaps with it.

  • The interface for selecting shear studs has been improved. Due to improvements made to the Open BIM Database, the way studs are selected has been slightly modified. Previously, studs downloaded from a manufacturer's catalogue and user-defined studs were included in a single library. In the current version, the selection is made independently for "Manufacturer's catalogues" or "User punching shear studs". Furthermore, the "Generate reinforcement" panel has been simplified.

  • The interface for selecting waffle slab forms when entering this panel type has been improved. Due to improvements made in the Open BIM Database, the way users select forms from manufacturers' catalogues and the user library has been slightly modified. Several forms can now be imported from a manufacturer's catalogue or a library without having to enter the selection panel as many times as the number of forms to be imported into the project.

"Regenerate the GUID (Global Unique Identifier) of the project elements" option

By checking this option in "BIMserver.center" > "Share" or "Export" > "IFC", new unique identifiers (GUIDs) will be generated for the structural elements and therefore they will be considered as new project elements.

This option is useful in certain cases, such as when modelling a project with identical structures. Each element can now be generated with its own globally unique identifier (GUID) for each independent structure.

This allows users to draw each structural element independently within the project and avoid having to redo the job.

Editing the clear covers of floor slabs and waffle slabs

As of version 2024.e of CYPECAD, both the effective covers of floor slabs and waffle slabs and the clear covers can be edited.

The clear covers entered are used to correctly arrange the punching shear studs, to perform fire resistance checks more accurately and to determine the position of the reinforcement bars to be exported to the BIM model.

When reading older jobs, the clear cover is automatically assigned by deducting 5 mm from the effective cover.

Design values of the reduced axial force by column and by floor

In CYPECAD version 2024.e, in the "Column, shear wall and wall forces and reinforcement" report, the "Design values of the reduced axial force by column and by floor" chapter has been added, which shows the maximum design value of the reduced axial force, for the persistent-transient combinations and the seismic and accidental combinations.

This chapter is enabled for the following standards: Eurocode 2, Spanish structural code "Código Estructural" (Spain), BS-8110 (UK) and NTC (Italy).

Exporting rebars from curved spans of staircases and ramps to the BIM model

The export of rebars from curved spans of staircases and ramps to the BIM model has been implemented.

In the current version of the program, CYPECAD exports the reinforcement of the following element types:

  • Concrete walls
  • Columns
  • Shear walls
  • Beam frames
  • Staircase
  • Ramps
  • Foundation elements (footings, pile caps, centring and tie beams)
  • Floor slabs (waffle slabs, joist slabs, hollow core slabs, composite slabs and flat slabs)
  • Corbels

These rebars can be viewed in StruBIM Rebar, along with rebars exported from the StruBIM Shear Walls program.

They can also be viewed in CYPECAD from the "Results" tab (Groups > 3D view with details).

Stair and ramp reinforcement editing options: Divide bars, Join bars, Divide automatically according to the maximum length

In the "Edit reinforcement" option from CYPECAD's "Stairs" and "Ramps" menus, the bars of the longitudinal reinforcement can be divided at a point, generating the necessary overlap to guarantee the transmission of forces from one bar to the next. The division can be carried out manually or the program can choose to do it automatically, respecting the maximum length of the bars defined. Bars that have been previously divided can also be joined together.

Intermediate supports between straight and/or curved ramp spans

In CYPECAD version 2024.e, intermediate supports can now be used between two consecutive spans for ramps.

Like lateral supports, intermediate supports transmit the load to the elements on the floor below or to the elements on the floor above, depending on the support option chosen.

Shortcuts for all applications

CYPE apps have keyboard shortcuts common to all programs. In versions before 2024.e, each program displayed the keyboard shortcuts for each app via the "Search and activation of commands and options" in the top left-hand corner of the programs.

As of version 2024.e, the "Shortcuts for all applications" tab has been implemented in the dialogue box displayed when selecting this option and it shows all the keyboard shortcuts common to CYPE apps.

Other improvements and corrections

CYPECAD version 2024.d includes the following improvements and corrections to the program for some specific cases:

  • Pre-stressed ceramic slabs for floor slabs manufactured by Cerámica Pastrana, S.A. have been added. By incorporating the technical data sheets of these products in the program, they are now available for use in the "Selection of hollow core plates".

  • The design of portal frames has been modified to consider paragraph 5.6.3(3) of Annex 20 of the Spanish structural code "Código Estructural" as well as Eurocode 2, Part 2-2. In order to meet the criteria indicated in these sections, in the case of fire resistance equal to or greater than R90, an extension of the negative reinforcement is applied up to 0.3 times the span length.

  • The updating of DXF/DWG templates by pressing the F5 key has been improved. In the previous patch, there was a new implementation for updating the templates, if new layers appeared, these were automatically made visible. This was made for updating via 'Edit templates > Import templates - Update file'. The same now applies when pressing the F5 key on the main screen.

  • The “Diagrams of pressures acting on the wall > Pressure diagrams list” has been improved. Previously, when adding a "Generic pressure diagram" after having entered another one without accepting the panel, the data of the first one was lost.

  • An error that could occur in the "Recover reinforcement copy of all groups" option has been solved. This occurred when the angle of the longitudinal reinforcement of a slab was greater than 180º. Now, when an angle greater than 180º is entered, in a flat slab or a waffle slab, it is automatically modified.

  • The entry of grid lines has been improved. Templates defined in "Column definition" can now be snapped.

  • An error that could occur in some situations when displaying the 3D view of concrete walls with continuous reinforcement on some floors has been fixed.

  • The 3D view of the reinforcement of circular frames, or frames where the origin coincides with the end, has been improved. Due to a programming error, in these cases, every time "3D view with details" was launched, the order of the beams in these frames was inverted and the reinforcement was shown alternately, correctly positioned and incorrectly positioned.

  • The "Electrowelded meshes > Check" has been improved. The checking process has been optimised to reduce processing time. More optimisations of this kind will be carried out in future versions.

  • The entry of generic column sections has been improved. The ability to enter points by snapping the elements of a template, which was lost in version 2024.c, has now been restored.

  • An error that could occur very rarely during the analysis process when a wall was in contact with flat slabs and the direction of this wall was not parallel to the direction of the reinforcement of one of the slabs involved, has been solved.

  • The ratio analysis for primary beams according to Eurocode 8 requirements 5.4.3.1.2(5)P and 5.5.3.1.3(5)P has been improved.

  • An error has been corrected in the units shown for air density in the wind action report according to Eurocode 1-4.

  • The steels and bar diameters commonly used in Thailand for the ACI 318M-11 (USA) concrete standard have been incorporated.

Reading the fixed points of columns entered in REVIT

As of version 2024.d, CYPECAD has implemented the reading of the fixed points of columns included in the IFCs generated by REVIT. For this reading to be carried out correctly, REVIT must use column families created with a fixed point which is the origin of the coordinates of this IFC.

More information on how to create or use these families can be found at https://learning.cype.com/en/faq/how-can-the-fixed-points-of-revit-columns-be-read/. In the same link, users can also download the parameterised column families supplied by CYPE for different Revit versions.
