4.5.5 How to use classifications

Elements may be classified according to multiple systems, so the result of element.classification is always a list – for more detail refer to section 4.4.6, How to use a list of values.

There are two ways to use element classifications in expressions:

1. Searching the list of attached classifications for a name, e.g. one exactly matching “Column” is included:

   element.classification includes “Column”

   …or that at least one classification name contains the word “Wall”:

   element.classification contains “Wall”

2. Using the details of the element classification from a specific system in an expression. The system is named in the same way as other list items, e.g. materials etc:

   element.classification("Uniclass 2015")

   Once a specific system has been named, there are two pieces of information that can be referenced from the element’s classification:

   1. Code

      element.classification("Uniclass 2015").code = "EF_40_30"

   2. Name

      element.classification("Uniclass 2015").name = "Furnishings"
