- Updated Leica integration to support the latest Disto D2 and X6 models—so you can use the most modern measuring tools available. - You can now import XLSX files. Export your data, tweak it in Excel, and re-import it to apply bulk updates in seconds. Yes, mass edits just got a lot less painful. - Inventory, finally where you need it. Locations, floors, and projects now include a dedicated Inventory tab—giving you a clear, editable overview of everything inside. No more hunting around. - Not everything needs to be out in the open: You can now manage objects directly in the inventory without placing them on the floor plan. Because sometimes reality is not perfectly drawn yet. - Locations can now be created in the Location Manager even if they’re not yet on the floor plan. Perfect for planning ahead (or catching up later). - Added the ability to move walls by freehand dragging, accessed by a button on the currently selected wall. - Bring your existing plans with you: PDF import is now supported in Background Images—making it easier to work with large-scale drawings and detailed plans, whether they were created elsewhere or simply saved as PDF. - Improved UI layout for less common screen ratios. - Various minor fixes and optimizations to keep everything running smoother behind the scenes.
