What's New

Added ULS stress-strain model toggle in the Concrete panel: choose between the rectangular stress block (EC2 Fig. 3.5, default) and the parabolic-rectangular profile (EC2 Eq. 3.17) for more accurate non-rectangular compression zone analysis

Bug Fixes

Fixed display settings (column visibility, show envelope subs, grouping mode) resetting when navigating between pages
Fixed Results panel growing excessively wide when utilization ratios exceed 100%, squeezing the cross-section view
Fixed interaction diagrams being broken (crossing lines, malformed surfaces) when using the parabolic-rectangular concrete stress block
Fixed incorrect reinforcement force direction shown in ULS analysis results (sign convention correction)
Fixed safety class factor (\(\gamma_d\)) incorrectly being applied for non-Swedish national annexes

Swedish safety classes now use the SK1/SK2/SK3 notation and the associated \(\gamma_d\) factors have been corrected
Interaction diagram labels are now automatically decluttered: when many load combinations cluster together, only the most representative labels are shown
Dimension labels now sit closer to their lines and stay at a consistent distance regardless of zoom level
Moment arrows now display their value (e.g. "\(M_y\) = 21 kNm"), scale proportionally to moment magnitude, and only appear on the Load Cases and Load Combinations pages
Minor fixes to table keyboard navigation
Minor UI improvements to the Load Combinations page
General stability improvements and minor visual fixes
