# RAY

Import Autodesk® Revit™ geometry and data into Rhino®

**RAY** in Rhino imports what [RAY for Revit](/beam/beam-for-revit/ray.md) exported: geometry, materials, parameters, levels and coordinates.

## Import

Click **RAY** on the [panel](/beam/beam-for-rhinoceros/using-rhino-beam.md#tool-buttons).

{% tabs %}
{% tab title="Windows" %}
Pick an export from the list. It shows the files in the current [.beam directory](/beam/beam-for-rhinoceros/beam-directory.md) by name, newest first. The label reads **Import Geometry** for a `.3dm` file and **Import Properties** for a `.bin` file. Click **BEAM** to import.

{% endtab %}

{% tab title="macOS" %}
Pick a `.3dm` or `.bin` file in the file dialog.
{% endtab %}
{% endtabs %}

What happens next depends on the file type:

| File   | Content                                       | Result                             |
| ------ | --------------------------------------------- | ---------------------------------- |
| `.3dm` | Geometry                                      | Imported into the current document |
| `.bin` | Parameters, materials, levels and coordinates | Opens the properties dialog        |

## Import geometry

Geometry arrives on layers built from the Revit elements, by default `Project::Category::Subcategory`. Elements made of several parts are grouped. Revit materials become Rhino materials.

Each object carries its Revit **Family : Type** as data, and adaptive components carry their **Mark**.

To change the layer names, set up a [layer mapping](/beam/beam-for-revit/ray/layer-mapping.md) before you export from Revit.

## Import properties

A `.bin` file opens a dialog listing its **Parameters, Materials, Levels and Coordinates**. Tick what you want and click **OK**.

| ------------------ | ---------------------------------------------------------------------------------------------------------------------------- |
| Parameters         | Added as [custom parameters](/beam/beam-for-rhinoceros/parameters.md)                                                        |
| Materials          | Added as Rhino materials with the Revit colours                                                                              |
| Levels             | Matched to existing [levels](/beam/beam-for-rhinoceros/levels.md) by name, then by height. Otherwise a new level is created. |
| Shared Coordinates | Added as a named CPlane, to use as the **Location** when you export                                                          |
