In AR Foundation, you can track planes, feature points, etc. Is it possible to create a 3D model of a space to scale (in Blender, for example) and use the tracking features of AR Foundation to align the virtual space to the actual one? The use case is being able to place objects in the virtual space that map to real-world objects and create a path from the user to the object for navigation purposes.

  • \$\begingroup\$ I think you'd want to place markers in the building — either using existing highly-visible unique landmark points or printing some QR -code-like fiducial stickers to place strategically so that multiple are in view in any frame of interest. Then locating and orienting your phone in the space is just a triangulation from the visible markers, given their known placements within the building. \$\endgroup\$
