> Launch of ASCE 7-22 Directional Procedure, Masonry Gravity Wall LRFD, and 3D structural model rendering.

## What's New & Improvements

### **Engineering Calculators:**

* [**Masonry Gravity Wall (LRFD)**](https://calcs.com/calculators/masonryWallLRFDTMS402_602-22) **🇺🇸:** **NEW!** Introduced the first version utilizing TMS 402/602-22 strength design methodology, featuring rectangular stress blocks and dynamic phi factors via strain compatibility.
* [**Wind Loads MWFRS (ASCE 7-22)**](https://calcs.com/calculators/loadsWindCnCASCE7-22) **🇺🇸:** Added the complete **Directional Procedure** with new wind direction inputs, direction-dependent roof angles ($\theta_{dir}$), and comprehensive pressure coefficient tables.
* [**Wind Load Parapets (ASCE 7-22)**](https://calcs.com/calculators/loadsWindCnCASCE7-22) **🇺🇸:** Implemented dedicated pressure calculations for both MWFRS and C\&C, including parapet-top exposure calculations.
* [**Snow Load Drifts (ASCE 7-22)**](https://calcs.com/calculators/loadsSnowASCE7-22) **🇺🇸:** Fixed leeward drift calculations to strictly enforce $8 \times h_c$ width limits and prevent drift heights from exceeding available clear height.
* [**Steel Composite Beam (LRFD)**](https://calcs.com/calculators/steelCompositeBeamLRFDAISC360-22) **🇺🇸:** Corrected short-term and long-term deflection logic specifically for cases involving precamber.
* [**Steel Bolt Analysis**](https://calcs.com/calculators/steelBoltAnalysisASD) **🇺🇸:** Updated technical references to include the **AISC Steel Construction Manual 16th Edition**.
* [**Wall Footing**](https://calcs.com/calculators/foundationsWallFootingUSA) **🇺🇸:** Updated template to default to **IBC 2024 / ASCE 7-22** standards with revised clause citations.
* **AU/NZ Steel Sections 🇦🇺 🇳🇿:** Resolved calculation errors for C350L0-T1 sections caused by string-comparison logic in the template back-end.

### [Atlas Tube Connection Hub](https://www.atlastube.com/hss-connections-hub/)

* [**WF-to-HSS Shear**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** The **Extended Configuration** now supports single vertical bolt rows, single-bolt-per-row options, and user-defined vertical bolt spacing inputs.
* [**HSS Round X-Connection**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** **NEW!** Developed comprehensive design for round HSS X-connections including member force interaction and AISC 360-22 limits of applicability.
* [**HSS-to-WF OMF Seismic**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Implemented **Ordinary Moment Frame** seismic limit states with SDC determination and Table 12.2-1 validation.
* [**Bolted Splice Shear**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Added comprehensive shear limit-states covering column yielding/rupture and plate block shear. Now enforces a 4x4 bolt grid maximum per AISC 316-22.
* [**HSS-to-WF Shear**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Extended end-plate connection support for combined axial and shear demands with new governing load combination tracking.
* [**HSS Truss Connections**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** Enhanced UX with a new "General HSS - Truss" preset and improved connection classification displays.
* [**Brace-to-Column**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸:** Extended support for HSS beams and columns with new web transverse shear yielding checks.
* [**Steel Connection Stiffeners**](https://www.atlastube.com/hss-connections-hub/) **🇺🇸 🇨🇦:** Fixed guidance messages that incorrectly suggested reducing stiffener lengths; logic now correctly recommends increasing length for HSS/WF moment connections.
* **Shuriken Bolt Validation:** Corrected workable-flat validation placement from beam to column widgets across all HSS Moment and Splice templates.

### [Calcs Builder](https://calcs.com/builder)

* **Preset Management:** Introduced advanced `referenceId` dependency tracking with migration tools to identify and fix orphaned references.

### **Platform Improvements:**

* **Homepage Redesign:** Rebuilt the main dashboard with a modern responsive layout, improved project tables, and "Quick Start" shortcuts.
* **Project Sidebar:** De-restricted visibility of the "Calculation Upgrades" link, allowing users to move templates to newer code editions more easily.
