# Classifications

Assign Uniclass codes to families

You can give each family a Uniclass code. BEAM writes it to IFC as a classification reference, and shows it in schedules.

## Load a Uniclass file

BEAM reads the classification tables published by NBS. Download the table you need, such as Products (Pr) or Elements/functions (EF), as `.xlsx` or `.csv`.

1. Click the gear (**Ifc Settings**) on the panel.
2. Open the **Classification** tab.
3. Click **…** and pick the file.

See [Classification settings](/beam/beam-ifc-for-rhino/settings/classification.md) for the name and edition written to IFC.

## Assign a code

1. Select an object in the family.
2. On the panel, open the **Type** tab under **Family Parameters**.
3. Click **…** next to **Uniclass**.
4. Search for a code or title, or browse the tree.
5. Select an entry and click **OK**.

The field shows the code and title, for example `EF_25_10 — Walls`.

To switch to another table, click **…** (**Change Uniclass file**) at the top of the Uniclass dialog.
{% endhint %}

## In IFC

On [export](/beam/beam-ifc-for-rhino/export.md), each code becomes an `IfcClassificationReference` linked to the family's elements. On [import](/beam/beam-ifc-for-rhino/import.md), BEAM reads classification references back into the **Uniclass** field.
