A BIM Object is a digital description of products or materials that, when combined with other BIM objects, create a BIM Model.
It is detailed information that defines the product and the geometry that represents the product’s physical characteristics. The visualisation data that gives the object a recognisable appearance and behavioural data, enables the object to be positioned or to behave in exactly the same way as the product itself.
There are two primary types of object: component and layered. The component objects are building products that have fixed geometrical shapes such as windows, doors, boilers etc. Layered objects are building products that do not have a fixed shape or size such as carpets, roofing, walls and ceilings.
