SpatialComposition
alias: spcomp
version: 1.0.0
Provision of a spatial structure of the project by aggregating spatial elements.
This schema contains classes that are used to model the spatial structure. That spatial structure is often used to provide a spatial project structure to organize a building project.
A spatial project structure might define as many levels of decomposition as necessary for the building project.
Due to the importance of IFC in coordinating physical infrastructure, the classes in the schema are intended to have a 1:1 instance mapping (not class mapping!) with IFC that will work for transformations in either direction. It is expected that round-trip transformations may result in changes that provide an equivalent, but not identical model.
