# Properties

In Rhino, use the [panel](/beam/beam-for-rhinoceros/using-rhino-beam.md#panel) to assign the following properties to Rhino objects:

* Family - The family that owns the object.\
  \&#xNAN;*Objects in blocks are always assigned to the block family.*
* Subcategory - Subcategory of the object.\
  \&#xNAN;*This property is not available for System Families*.
* Material - Material to apply to the object.\
  \&#xNAN;*This is always the Rhino material assigned to the object.*
* Data  - Extra metadata visible only in Dynamo.

## Assigning properties to Rhino objects

Selecting suitable objects will activate the [panel](/beam/beam-for-rhinoceros/using-rhino-beam.md#panel).\
Type values in the parameter fields to assign the property to one or more geometries.\
Press enter to apply.

{% hint style="info" %}
When a material is not present in Rhino, BEAM will automatically add it to the document. You can then adjust its appearance in the Rhino Material Browser.

If an object’s material is initially assigned by layer, BEAM will switch it to by object so it can be managed individually. The *Material* property in the panel always refers to the Rhino material assigned to the object. Editing this property will immediately update the object’s material in Rhino.

{% hint style="info" %}
When importing into Revit, any missing subcategory or material will be created automatically with a similar appearance.
