A model can consist of bodies of various types. The VEBody object has a type attribute to discover the object type of that particular space. Object types can be categorised as follows:
3D bodies: rooms, local or topographical shades, adjacent buildings
2D bodies: masterplanning surfaces, boundaries
1D bodies: annotations
Each body has a unique ID. The ID is unique only within the model that contains the room. In a variant model, the same room will have the same ID - this allows you to find the same room across models and compare them.
