The provisions of the exchange requirement [Exchange Building Model - Sketch]must be satisfied. This includes all context information provided through project details including:
- the name of the project and, optionally, the phase of work of the project
- the default units used throughout the project
- the world coordinate system
- the coordinate space dimension
- the precision used within the geometric representations
- true north relative to the world coordinate system
- different types and scales that can be used for representing stored shapes (symbols) where these have multiple representations (e.g. multi-view blocks)
\
Additionally, the building information model provides the following information proposed by the building designer that is required for electrical systems design:
- spatial structure element s (site, buildings, storeys, spaces)
