42. Spatial Grid, Zone and Dimensional Reference
Stable section ID: S05-CON-015-SECTION-43 · 12 content blocks
A Spatial Grid is a controlled geometric framework used to locate, coordinate, dimension, and relate System05 entities within a common spatial system.
A Zone is a declared spatial region assigned one or more functions, constraints, access conditions, or engineering responsibilities. Zones may include structural zones, functional zones, utility zones, envelope zones, clearance zones, installation zones, inspection zones, Tool Corridors, safety zones, and reserved future-use zones.
A Dimensional Reference is an authoritative dimension, point, line, plane, surface, axis, or coordinate frame from which geometry is established or verified.
The spatial framework shall distinguish among:
global, site, building, assembly, module, component, interface, and robotic coordinate systems;
nominal and actual dimensions;
occupied and reserved space;
permanent and temporary zones;
physical boundaries and functional boundaries;
reference geometry and manufactured geometry.
The Spatial Grid provides coordination but does not require every component to possess identical dimensions. Components may differ where they preserve applicable interface positions, clearance requirements, dimensional relationships, and compatibility conditions.
Every coordinate-dependent instruction shall identify its origin, axes, orientation, datum, units, and applicable version. Transformations between coordinate systems shall be explicit, controlled, and verifiable.
