Introducing Project Audit & Evidence Pack — a new way to turn IFC model checks into a reviewable record. • Run Model Health on its own or combine Model Health, IDS Validation and Coordinate Checker in one audit. • Choose an IFC revision and IDS ruleset, with separate source fingerprints and clear verification status. • Review findings and evaluation coverage, with honest pass, warning, failure and incomplete outcomes. • Save audit history and reopen previous results without rerunning the checks. • Export a validated ZIP containing a PDF report, CSV findings, JSON results and a SHA-256 manifest. Also improved: • IDS importing from file providers, including Google Drive on Mac. • Model and revision selection when files share the same name. • Unlock All discovery on the iPhone Workspace for customers who have not purchased the full toolset. • General usability and file-handling refinements across iPhone, iPad and Mac. Project Audit is included for Unlock All owners and customers who own all 14 original Pro Tools. No separate Project Audit purchase is required for eligible owners. Results reflect supported model checks and available data; incomplete coverage is clearly reported rather than treated as a pass.

**What's New in Version 5.1** We've given IFC Viewer's Pro Tools experience a fresh new look! • **Discover more:** A redesigned Workspace promotion makes it easier to explore powerful professional IFC tools. • **Unlock All, reimagined:** A vibrant new design showcases Clash Detection, Quantity Takeoff, Model Compare, Federation and more — all available with one one-time purchase and no subscription. • **Improved purchasing experience:** Clearer pricing information and better recovery when App Store product details are temporarily unavailable. The same powerful IFC tools, now with a more polished and engaging experience.

**What's New in Version 5.0** A major update to IFC Viewer's 3D viewing technology, with improvements to model information, clash reporting and overall reliability. • **Upgraded 3D Viewer** – Updated our That Open rendering engine with newer Components and Fragments technology, providing a modernised foundation for viewing IFC models. • **Improved IFC Element Identification** – Enhanced IFC class, GlobalId and property handling for more accurate element identification. • **Enhanced Clash Detection** – Improved clash result information, element identification and BCF exports, including more complete model and component references. • **Improved Federation Information** – Refined element metadata handling across federated IFC models. • **Stability and Compatibility** – Under-the-hood improvements to the viewing infrastructure while maintaining support for existing tools and add-ins. Thank you for using IFC Viewer! We're continuing to develop new features and improvements to make working with IFC models even better.

**What's New in Version 4.1** This update focuses on simplifying IFC Viewer and improving the foundation for future enhancements. • **Streamlined 3D Viewer** – Removed the legacy Classic Viewer, making That Open our dedicated 3D rendering engine. • **Improved Reliability** – Refined viewer recovery and Safe Mode handling for a more consistent experience when opening IFC models. • **Smaller App Size** – Removed obsolete rendering components and unnecessary resources. • **Continued Feature Support** – Maintained compatibility with model federation, Quantity Takeoff, Clash Detection, Model Compare and existing viewer tools. Thank you for using IFC Viewer! More exciting improvements are on the way.

IFC Viewer 4.0 is built for iPhone Duo. Open the model on the cover. Unfold it across both screens. Fold it back and the same model is still there — no re-import, no lost selection. The viewer follows the device: closed, partially open, fully open, portrait or landscape. Quantity Takeoff, Clash Detection, Model Compare and Federator keep the model you already loaded. Existing tool purchases and Unlock All restore as before. £2.99 opens the model. £24.99 unlocks all 14 tools, once. Local. No subscription. A desktop BIM licence does not fold into your pocket. This does.
