Preparator: the wall-measurement machine for exhibitions

Field notes

Preparator keeps a Collection of artworks separate from Projects containing rooms and walls, then lets users return pieces from a wall to the Collection. Its installation model includes picture-wire distance, wall padding, spacing, measurement direction, and rectangular obstructions positioned by coordinates. The page says work remains in the browser on the current device, with workspace export and import available for backup or transfer. An Installer PDF is exposed as an export option in the project interface.
