Most 3D editors deal in triangles. They know about vertices and materials, but they have no idea that the box on the second floor is a window or that the pipe behind the drywall is part of the HVAC system.
That's fine for rendering. It's useless if you want a machine to reason about the building.
The scene graph
The Pascal Editor sits on top of a semantic scene graph. Every element in the building has a type, metadata, and relationships to other elements. A wall isn't geometry — it's a wall, with a material, a thickness, a condition, and a connection to the rooms on either side.
This is the part that matters: the same data model that lets you click a roof and see its inspection history also lets an AI agent traverse the graph and answer "which components are past their expected lifespan?" without anyone walking the building with a clipboard.
Humans get a 3D editor. Agents get a structured graph. Same data underneath.
