Typically stored in building information models, and defines the shared and private properties of a single occurrence of the component type. For example, a SingleTimberDoorF60_3’x7’ in Room 001, is defined as:
- Type: single
- Material: timber
- Fire rating: F60
- Size: 3’ x 7’
- Door number: D001
- Sound proof: true
- Color: red
The instance inherits some or all of it’s parent type shared properties, and can also have additional private properties (such as door no: D001; and sound proof: true). It can also have redefined shared properties that become private properties (such as color: red).
