09.02.2026
Fixed an issue where support reactions were not shown when a rod hinge was used at a support node. Support nodes now work correctly with both hinges and elastic supports
Previously, when a hinge was inserted into a rod connected to a support node, support reactions were not displayed in the results view. Displacements and internal forces were calculated correctly, but reactions at that support node were missing whenever a support and a rod hinge were used simultaneously. This issue has been fixed. Support reactions are now displayed correctly in all such cases. Moreover, support nodes can now be combined not only with rod hinges but also with elastic (spring) supports, providing greater modeling flexibility.
improvement
29.01.2026
Added keyboard shortcuts for faster workflow
New hotkeys: Ctrl+A (select all), F1 (help), F2 (grid snap toggle), F3/F4 (unit divisions). Breaking changes notification now appears for returning users.

Analysis results are now permanently saved and preserved across all future updates, ensuring consistent results for stored projects
Previously, all models were stored in the database and could be reopened at any time, but the analysis results were not preserved whenever updates were made to the software. While recalculation in 2D is typically fast, this behavior created the impression that results were inconsistent or temporary. We have now revised this approach — analysis results are fully preserved across all future program updates and website deployments, ensuring stability and consistency for all saved projects.
feature
27.01.2026
Added a Save As option to create a copy of the current project for continued editing
Previously, there was no way to “Save As” and create a copy of the current project. This made it inconvenient to branch off from an existing model, as users had to reload the page and start a new project manually. A Save As feature has now been added, allowing you to create a duplicate of the current project and continue working in the copied version.
feature
27.01.2026
Enhanced the Element Properties panel with updated buttons and boundary icons
The visual design of the Element Properties panel has been improved, including updated buttons and refreshed boundary-condition icons for a clearer and more consistent interface.
feature
20.01.2026
Added a dedicated Copy button to the mobile interface, replacing the unintuitive long-press action
In the mobile version, copying elements previously required a long-press to open the context menu, which was not intuitive for many users. A dedicated Copy button has now been added to the right-hand panel, making the action clear, accessible, and consistent with the rest of the interface.
fix
20.01.2026
Fixed unintended canvas interactions when tapping between mobile zoom buttons, preventing accidental node creation
In the mobile interface, the zoom controls (“+” and “–”) are placed vertically on the right panel with small gaps between them. Previously, users could accidentally tap these gaps while trying to zoom, and since a double-tap on the canvas creates a node, this often led to unintended node creation and disrupted the workflow. This issue has now been fixed - tapping the space between the zoom buttons no longer triggers any canvas interaction.
fix
18.01.2026
Added a Settings section with the option to delete your account
Previously, the personal account menu did not include an option to delete a user account, which limited users’ control over their data. A new Settings section has now been added to the account menu, where users can easily delete their account if they choose to do so.
improvement
18.01.2026
Improved diagram label readability with semi-transparent backgrounds and lighter text
To improve readability, the background of diagram labels has been made semi-transparent and the font weight has been reduced. Previously, the opaque label background could obscure parts of the diagram and hide other annotations.
feature
18.01.2026
Added detailed per-element diagrams (values at 10 points) and the ability to show diagrams only for selected elements for improved clarity
A new feature has been added that allows viewing detailed results for an individual element. You can now inspect displacements, internal forces, and stresses at 10 points along a selected rod. To use this feature, switch to the Results mode and select a single element to display its detailed diagram. You can also switch between elements while staying in this mode. Additionally, it is now possible to display diagrams only for the selected elements, preventing label overlap and significantly improving readability.
breaking
18.01.2026
End releases are now element-based rather than node-based, allowing multiple releases at the same node. A redesigned End Releases window offers flexible assignment options and supports mobile devices
The logic for assigning hinges and semi-rigid end releases has been completely reworked. End releases are now properties of elements, not nodes. The End Releases dialog is accessed through the Element Properties panel when rods are selected on the canvas. This update removes the previous limitation of having only one release per node, enabling multiple elements connected to the same node to have their own individual hinges or semi-rigid releases. The new End Releases window provides a clear, flexible interface for assigning Rz and rotational stiffness values and displays only the currently selected elements. The interface is also fully adapted for mobile devices.
fix
14.01.2026
Fixed incorrect rod number scaling on mobile devices; labels now display properly at all zoom levels
Number labels were previously displayed incorrectly on mobile devices — in some cases they would disappear at high zoom levels or appear excessively large at low zoom levels. This issue has now been fully resolved, and all labels render correctly on Apple devices.
fix
08.01.2026
Fixed incorrect text and number scaling on iOS and macOS; labels now display properly at all zoom levels
Text and numeric labels were previously displayed incorrectly on iOS and macOS devices — in some cases they would disappear at high zoom levels or appear excessively large at low zoom levels. This issue has now been fully resolved, and all labels render correctly on Apple devices.
fix
08.01.2026
Improved mobile zoom behavior — the view no longer shifts diagonally, and the center stays fixed during zooming
On mobile devices, zooming is performed using the + and – buttons. Previously, the viewport would shift diagonally when zooming, causing the screen to “jump” and making navigation uncomfortable. This behavior has been fixed — the current center now remains stable during zoom, providing a much smoother and more intuitive experience.
fix
07.01.2026
A hosting-related issue briefly affected analysis requests, causing error messages has been fully resolved
We experienced a temporary issue caused by changes on our hosting platform, which disrupted how the server processed analysis requests. As a result, you may have seen error messages in the last 24 hours like the one shown when attempting to run a calculation. The entire processing chain has now been fully restored, and the service is operating normally. We apologize for the inconvenience and appreciate your patience.
feature
07.01.2026
Added support for splitting rods into unequal segments and enabled splitting for multiple selected elements
Previously, rods could only be split into a specified number of equal segments. A new option has been added that allows splitting a rod into two unequal parts by defining the distance from the rod’s starting node. In addition, rod splitting now works when multiple elements are selected.
breaking
05.01.2026
Added user accounts with project saving (up to 50) and shareable editable model links, accessible even without registration
A major new feature has been added — the user account system. It allows you to save your projects (currently up to 50 per user) and share an editable model via a link. The recipient can open and edit the shared project even without registering an account.
fix
30.12.2025
Mid-span force and stress values are now displayed for clearer diagrams
Improved force and stress diagram labels: values are now also displayed at the mid-span of each element. Previously, when the maximum value coincided with an end value, no label appeared in the middle, resulting in unclear visualization
feature
29.12.2025
Added Beam Wizard
A beam creation wizard has been added, including full support for the mobile version. It now allows you to generate multi-span beams with predefined materials and sections in just a few clicks
