Disney’s Imagineering is incredible!
One of the major tools Imagineering used to keep everyone on the same project page is their BIM (building information modeling) tool. The tool takes a combination of 2D plans, 3D models, infrastructure and set dressing information and combines them into one massive interlocking source of truth for all departments to pull from. Teams were able to drill down from an overview of the land in 3D to the design plans for a specific doorway control panel.
Basically, it’s foundational geometry from across the project that’s then fed into the Unreal engine and presented in 3D. Like a 3D world from a game, but it’s a real place with real plumbing, architecture and technology underneath.
