  • When offsets for bars are added, it is possible to consider the angle of pure rotation.

  • When the elements are copied or moved by two nodes, either by rotation or symmetrically (mirror copy), there is an option that allows you to rotate the local axes of the bars and assign the calculated angle of pure rotation. The specified sections of bars, loads in the local coordinate system, and offsets in bars are oriented according to the new location of the local axes.

  • It is possible to copy selected properties for load cases: type of load case, subproblems, type of dynamics, account of static load cases (mass accumulation for dynamic analysis), selective account of masses in elements, groups of mass redistribution in elements, eccentricities of mass application. It is also possible to copy the values of increasing factors fvk and damping ratios ksi for earthquake load cases.

  • For the list of material properties of reinforced concrete structures (type/concrete/reinforcement) and masonry reinforcing structures (masonry/reinforcement/strengthening), there are new options: 1) to find in the list the data assigned to the elements selected on the design model, and 2) to find on the design model the elements with the data highlighted in the list. 

  • A new option "Ignore parameters of filters" that allows you to temporarily disable the reaction to the set filters (selection criteria) in the "Polyfilter" dialog box.

  • Added option to edit the angle of deflection for adjacent bars; for this angle, it is allowed to combine the bars into one structural element (default 2.3°). Now, if the user specifies a larger deflection angle, it will be possible to combine curved elements of beams or columns into a single StE.

  • Option to customise the hotkeys and add corresponding commands to user-defined toolbars now applies to all flags of drawing (options for setting parameters for presentation of design model and information on it), as well as, mosaic plots of assembled and disassembled elements.

  • Option to select groups of structural elements, unified groups, unified groups of structural elements and structural blocks with the selection window. 

  • For bars, a new option to display section types and geometric properties on the model.

  • A new command that allows you to change the restraints at selected nodes.

  • The number of colours may be defined for the discrete colour palette (the palette is evenly divided within the extreme values) and to the colour palette by values (each division corresponds to a unique value of the mosaic plot of the displayed parameter).

  • The specified graphs of dynamic loads at nodes (seismograms, piecewise linear (polyline) load with uniform step, accelerograms in relative units) may be presented with account of specified coefficient to load/conversion coefficient of relative units to acceleration units.

  • When you define the data to compute the load at the specified nodes of the design model from its remaining part (load on the fragment), there is a new option to exclude nodes that do not belong to the elements of the fragment from the analysis.

  • The super-elements may be automatically snapped to the main model, in case super-elements were moved from a subdirectory to the directory with the main model.

  • When you define the default parameters for the new problems and new design options, it is now possible not to delete incomplete or conflicting data for reinforced concrete and steel analysis before analysis procedure.

  • Modified and extended with new commands the panels of the ribbon interface, as well as the menus and toolbars of the classic interface.
