 * A new document. Alternatively, the other objects will be created in the currently opened document.
 * A site. The Site object represents a piece of terrain, where your project will be located. You can give it a number of useful properties, such as street address and earth coordinates. Upon creation, the site is just an empty container for other BIM objects, but a 3D object representing the actual terrain can be attached to it later on.
 * A uilding. The Building object is a container for all the BIM objects that will belong to a same building. You can define a building type, and give it gross rectangular dimensions, that will be represented as a rectangle drawn on the ground (X,Y) plane.
 * A set of axes, by defining their number and spacing. Axes are used as guidelines to align 2D and 3D objects. These axes can be modified or new axes introduced later on.
 * A set of BuildingParts to represent levels. BuildingParts are generic BIM container objects that can be used to group other BIM objects in a number of meaningful ways, such as repeatable components or building levels.
 * A set of default groups inside each level. Groups can be used to organize your BIM objects in clearer categories, such as "Walls" or "Columns". They have no impact on the model itself, but often help to make your model structure clearer when it contains a lot of objects.
