AR Blueprint Viewer for Manufacturing

I need a focused AR application that lets our manufacturing and maintenance crews pull up 2D technical drawings and blueprints directly on their smart-glasses. The idea is simple: a technician looks at a machine, gives a voice or gesture command, and the relevant plan appears aligned to what they see, ready to zoom, pan, toggle layers, or mark-up while their hands stay free.

Key functions I expect
• Import of common plan formats (PDF, DWG, DXF) and quick cloud sync or local caching for offline areas
• Accurate spatial anchoring so the drawing “sticks” to the equipment even if the wearer moves around it
• Smooth navigation—gesture, voice, or simple controller input—to scroll, zoom, rotate, and switch sheets
• Lightweight annotation: highlight, add notes, then export the updated file back to our server
• Basic user management so only authorised staff access sensitive drawings

Nice-to-have (not essential for the first build) would be the option to expand into live remote support later on.

Please deliver the compiled app, source code, and a short deployment guide for whichever headset SDK you choose (we currently test on HoloLens 2 but are open to Vuzix or similar). I’m happy to provide sample blueprints and run quick usability checks during development.
