4.0 Object Properties & Property Grouping
This section of the standard defines the properties that should be assigned to a BIM object. It also discusses the grouping of properties and the assignment of properties to object types or object instances.
4.6 Classification properties
| | 4.6 Classification properties
This sub-section of the standard defines properties to be assigned to an object to classify the object type. As there is no universally adopted classification system, this sub-section allows for the application of multiple classification systems. |
4.6.1
| Classification system properties
|
| | Multiple classification systems can be assigned to an object by including the set of properties in Table 4D for each classification required.
NOTE: Substitute <ClassificationSystemName> in the property name for the required classification system and table designation, if applicable. For example, OmniclassTable23 Examples in Table 4D have used Omniclass Table 23. |
