# Rhino

> Stream Rhino geometry into Real-Time LCA via Speckle.

Use the **Speckle Connector for Rhino** to send Rhino geometry to a Speckle stream that a Real-Time LCA project listens to.

## Prerequisites

* A Rhino version supported by the Speckle Connector.
* Your Real-Time LCA **Speckle credentials** for `https://api.realtimelca.com` (sent by email when you activated your account — see [Introduction to Speckle](/user-guide/integrations/speckle)).
* A Real-Time LCA project configured with a Speckle Connection (see [Create a new project](/user-guide/project/create-new-project)).

## Install the connector

Install the Speckle Connector for Rhino from [releases.speckle.systems](https://releases.speckle.systems/). After restart, run `Speckle` from the Rhino command line to open the connector.

## Publish a model

1. Open your Rhino file.
2. Run `Speckle` and sign in to the Real-Time LCA Speckle server (`https://api.realtimelca.com`).
3. Select the **project** and **model** matching your Real-Time LCA stream.
4. Pick the objects or layers to publish.
5. Click **Publish**.

## Tagging geometry

Because Rhino doesn't have built-in BIM types, attach the parameter Real-Time LCA expects (by default `BIMTypeCode`) as **user text** on the objects or layers you publish. Real-Time LCA reads that key to group geometry into BIM types.
