> Migrated to hierarchical navigation and storage of duct transitions > Added optional new UI for iPads > Added particle physics for observing airflow through the duct transition > Added pressure drop calculator based on airflow requirements > With new hierarchical navigation, you can now copy duct transition files as needed

Updated to support iOS 17. Fixed Workshop view not using sheet metal texture in rendering, and fixed export to PDF so markup does not get stuck in a loop.

Now looks absolutely brilliant on iPad and Mac! The iPad and Mac version has been completely reimagined to take advantage of that additional screen real estate. When building a transition you now get to see the 2D & 3D views side by side with the option to make the 3D view full screen. Also if you use Stage Manager for iPad you can resize FieldFab and it will continue to look great as it automatically adjusts itself. The 2D views now show you the cutting lines more clearly by drawing red lines in areas you should mark on your sheet metal. The 3D view cross brake algorithm has been rewritten so, even if the face is heavily skewed, the point of intersection is in the proper spot.

Added auto save feature, fixed offsets producing inaccurate measurements, and allow for larger numbers in balance point calculator. Also includes a change log accessible from the main menu to see what has changed each update.

Rearchitected from the ground up to allow for additional functionality to be added to FieldFab. FieldFab now includes a Balance Point calculator which you can use for PTCS heat pump commissioning, and an intake combustion air calculator for figuring out whether you need to add a dedicated intake for gas powered equipment (Furnace, Water Heaters, etc.). Shareable links are fixed. Now if the name of your session contains any spaces or symbols, those get encoded into the link properly. Old link formats do not work with this version of FieldFab. Export to PDF now included! Now you can attach your transition designs to your company's CRM software in the form of a PDF or email it to sheet metal fabrication shops! Added another background for the 3D view, and added a feature to give the the ductwork a "cross brake" look. FieldFab now looks amazing on bigger screens such as iPads or Macs with Apple Silicon. TAB PRESETS! No more setting each tab individually. You can now activate one of the presets and save even more time building duct transitions. Measurements are now visible in the "All Faces" view so you can really see the effects of changing your measurements. Many more features are on the way. Stay tuned!

Various bug fixes: - Pressing the settings button from inside a session, followed by the back button, does not exit out of the session anymore - Number inputs have been rearchitected to use a custom keyboard input to ensure only valid measurements are inputted - Interface components that involve picking from a set of values look much better - Interface updates are asynchronous and are less likely to freeze your device - Making a side flat does not make the opposite side from the one you chose flat anymore Thank you for waiting so patiently for an update! It's been a long year as an independent app developer, full-time HVAC service tech, and full-time college student. More updates to come!

Maintenance update and bug fixes

By popular demand, FieldFab now allows number input using the keyboard! Fixed bug where number input doesn't work after updating to iOS 15

Now Open-Source! All of the source code is now freely available on GitHub for educational purposes. Fixed a bug where sometimes offsets do not update the total width of the duct properly.

Fixed half inch tabs not displaying properly in measurements page. Included additional help pop-up for workshop view. Fixed Augmented reality plane detection (ductwork moving around too much when viewing on camera). Additional performance increase (when not viewing 3D or AR tab, processing for those tabs are completely paused until reopening tab).

Massive improvements to the rendering system. Now includes an Energy saver mode to reduce GPU usage substantially while 3D models are not being viewed. Complete overhaul of the UI in preparation for more great features. FieldFab can now convert between metric and imperial measurements, and the interface for adjusting measurements has been improved. Bug fixes include no more crashes when viewing the AR view. You can now change the background of the 3D view to an image, or select any color on the spectrum for your viewing convenience. Also added the ability to make sides flat by long-pressing on the side while viewing in both 3D and AR view. Rendering quality and efficiency improvements include: -Photorealistic ductwork textures -Models only update when measurements change -Extremely accurate reflections on ductwork in both AR and 3D view -Tabs now show up in the AR view Always open to new suggestions and feedback!

Added experimental feature options and ability to change the texture that the ductwork is rendered with. The experimental layout puts the measurement inputs conveniently on the 3D view so you can witness the changes to the ductwork as you change the inputs.
