Release notes

New

• ✨New Attached Canopies C&C module for ASCE 7-16 and ASCE 7-22

Fixes

• Fixed issue preventing adding Snow drift cases when the roof slope is exactly 0°
• Corrected ASCE 7-16 hip and gable GCp, which began interpolating at the wrong minimum effective area
• Corrected monoslope roof pressures at exactly 3° and 10°, which used the neighboring figure
• Corrected roof pressures on buildings over 60 ft with 7° to 10° slopes, which used the low-slope table instead of the sloped-roof figures
• Corrected ASCE 7-10 roof pressures over 60 ft above 10°, which used the low-rise monoslope figure instead of the sloped-roof figure the tall-building figure requires
• Corrected hip roof corner zone GCp on 7° to 20° slopes, which used the wind-normal width B instead of the least horizontal dimension
• Corrected the reduced edge and corner zone width a, applied on 8° to 10° roofs and at exactly 300 ft of width where it does not apply
• Corrected open roof CN zones, sized from the effective wind area instead of the edge distance a
• Corrected C&C wall suction on buildings over 60 ft, which used qz at the zone elevation instead of qh
• Corrected MWFRS roof overhang pressures, which added 0.8 to the top-surface Cp instead of subtracting it and included internal pressure
• Corrected MWFRS wall pressures and line loads per level: the lowest tributary now starts at the base, and each tributary integrates its actual remaining height
• Corrected MWFRS open roof results when γ=0 and γ=180 land on different figures, which previously failed instead of reporting both
• Corrected which open roof figure MWFRS uses for each wind direction, h/L, and slope, including the low-slope monoslope exception
• Corrected ASCE 7-22 C&C overhang pressures in roof edge zones, which used the corner wall GCp instead of the interior wall GCp
• Corrected the ASCE 7-10 Exposure B Kz minimum, which was not applied to C&C pressures below 30 ft
• Corrected the ASCE 7-10 air density table behind Ke, whose values above 6,000 ft were listed against the wrong elevations
• Corrected the Kzt exemptions, which now apply below rather than at H/L of 0.2, hill height 15 ft in Exposure C and D, and 60 ft in Exposure B
• Velocity pressures above the gradient height no longer assume Kz = 2.01; they now require an engineer-approved value for that exposure and code edition

Other changes

• Clarified when the minimum ±16 psf C&C design pressure controls, while preserving the calculated pressure for review
• Roof pressure tables now appear in the MWFRS roof section
• Values you type are now saved when you leave the field instead of while you are still typing
• Added notes on roof inputs explaining when open building figures apply and which wall zone overhangs use
• Parapet roof zone choices are now limited to the zones that apply, and calculations now stop with a clear message when a roof shape or building height falls outside what the code covers
• Corrected wind code references, equations, and figure labels shown in summaries and reports
• Existing wind projects may show updated pressures when reopened, so re-check your wind results

Fixes

• Fixed ASCE 7-22 windward snow drift widths being cut short once the drift height reached the clear height
• Fixed ASCE 7-22 minimum roof snow load and rain-on-snow surcharge ignoring the structure Risk Category
