Beam / Cable
- In the Locate section dialog, the ability to adjust the position of the analytical bar for a group of selected beams has been implemented. This allows setting the correct placement of analytical bars for the entire group of elements in a single operation without editing each one individually.
- For more convenient work and clearer evaluation of analytical bar snap parameters, the corresponding properties have been moved to the object parameters. Now the user can directly view and edit the selected snap option: At the center of the bounding box, At the center of section mass, at the corners and sides of the section, as well as the snap values of the binding point along X and Y axes. This simplifies control of assigned parameters and speeds up adjustment of the analytical bar position.
- For more precise control of beam placement in the model, separate snaps have been added at the start and end of the bar. For each beam point, the standard set of snaps can be used: Free snap, From floor top, From floor bottom, and Specified level. This simplifies model generation and further editing of beam positions.
- A mechanism for explicitly defining relationships between beams has been implemented. Connections are formed based on PRB and displayed in the analytical representation even before the design model is generated, ensuring more accurate control of modeling logic and clear verification of connections between elements.
- For “Cable” objects, a new generation method has been added — “Catenary line”. It simplifies modeling of cable-stayed structures with a specific sagging shape that must be considered in both the physical and design models.
