# RAY

Export Autodesk® Revit™ geometry and data to Rhino®

**RAY** exports Revit geometry, materials, parameters, levels and coordinates to files that [RAY for Rhino](/beam/beam-for-rhinoceros/ray.md) imports. Elements arrive on Rhino layers named after their Revit category, which you can change with a [layer mapping](/beam/beam-for-revit/ray/layer-mapping.md).

RAY runs Rhino inside Revit, so Rhino 7 or 8 must be installed. See [Rhino inside Revit](/beam/beam-for-revit/using-beam-for-revit.md#rhino-inside-revit).

## Export

Click **RAY** on the [BEAM tab](/beam/beam-for-revit/using-beam-for-revit.md).

### Selection

| Option                                            | What it exports                                                                            |
| ------------------------------------------------- | ------------------------------------------------------------------------------------------ |
| **Edges**                                         | Edges you pick                                                                             |
| **Grids And Curves**                              | Grids and model or detail curves you pick                                                  |
| **Active View**                                   | Everything visible in the active view. The view must be a 3D view.                         |
| **Solid Elements**                                | Elements you pick, as solids and meshes. This is the default.                              |
| **Adaptive Components**                           | Adaptive components you pick, as polylines and points with their **Mark**                  |
| **Batch Export**                                  | Several Revit files at once. See [Batch Export](/beam/beam-for-revit/ray/batch-export.md). |
| **Parameters, Materials, Levels and Coordinates** | Project data, without geometry                                                             |

If you selected elements before clicking **RAY**, the **Selection** options are hidden and RAY exports your selection.

**Adaptive Components** and **Parameters, Materials, Levels and Coordinates** are not available in the Family Editor.

### Location

Where the Revit coordinates land in Rhino: **Internal Origin**, **Project Base Point** or **Shared Coordinates**. For shared coordinates, pick the location.

### Pick and save

1. Click **BEAM**.
2. Select the elements in Revit and click **Finish** on the options bar. Skip this for **Active View**.
3. Name the export in **Save As**. Use letters, numbers, spaces, `_` and `-`. Leave it empty for a random code.
4. Click **BEAM**.

RAY saves a `.3dm` file in the [.beam directory](/beam/beam-for-rhinoceros/beam-directory.md). Import it in Rhino with [RAY](/beam/beam-for-rhinoceros/ray.md).

## What you get in Rhino

* Elements made of several parts are grouped.
* Revit materials become Rhino materials.
* Each object stores its Revit **Family : Type** and subcategory.
* Adaptive components keep their **Mark**, so you can edit them in Rhino and update them with [URSA](/beam/beam-for-revit/ursa.md).

## Export parameters, materials, levels and coordinates

Choose **Parameters, Materials, Levels and Coordinates** and click **BEAM**. Tick what you want to export.

| Group                  | Contains                                                         |
| ---------------------- | ---------------------------------------------------------------- |
| **Parameters**         | Project and shared parameters, with their type and categories    |
| **Materials**          | Material names and colours                                       |
| **Levels**             | Level names and elevations                                       |
| **Shared Coordinates** | The active location: E/W, N/S, elevation and angle to true north |

Click **OK**, then name the file. RAY saves a `.bin` file. In Rhino, [RAY](/beam/beam-for-rhinoceros/ray.md#import-properties) creates the parameters, materials and levels, and the location as a named CPlane.
