# Properties

Add properties to Rhino® objects

Every object you send to Revit or IFC carries four properties. Set them in the **Object Properties** section of the [panel](/beam/beam-for-rhinoceros/using-rhino-beam.md#object-properties).

| Property        | What it is                                                                                   |
| --------------- | -------------------------------------------------------------------------------------------- |
| **Family**      | The family that owns the object. Objects inside a block always belong to the block's family. |
| **Subcategory** | The Revit subcategory of the object. Not available for system families.                      |
| **Material**    | The Rhino material of the object. It becomes a Revit or IFC material.                        |
| **Data**        | Free text. You can read it in Dynamo and Grasshopper.                                        |

## Assign properties

{% stepper %}
{% step %}
Select one or more objects.
{% endstep %}

{% step %}
Type a value in a field, or pick one from the suggestions.
{% endstep %}

{% step %}
Press **Enter** to apply it to every selected object.
{% endstep %}
{% endstepper %}

To set how the object appears in Revit views and detail levels, click the eye icon. See [Visibility](/beam/beam-for-rhinoceros/visibility.md).

## Materials

The **Material** field always shows the Rhino material assigned to the object. Editing it changes the object's material in Rhino straight away.

* If the material does not exist, BEAM adds it to the document. Adjust its look in the Rhino Material Browser.
* If the object took its material from its layer, BEAM switches it to **By Object**.

{% hint style="info" %}
Revit creates any missing subcategory or material on import, with a similar colour and transparency.
