About Visualization with Twinmotion

Twinmotion is a real-time visualization tool that enables you to produce high-quality images, panoramas, standard or 360° VR videos, and interactive presentations from design data. The changes you make in Twinmotion update in real time.

Your Revit model can be sent to Twinmotion using the Datasmith Exporter for Revit commands, included as part of the Twinmotion for Revit installer. The design and visualization process can then be continued in Twinmotion. As the Revit model progresses, changes can be synchronized back into Twinmotion to update the design with the latest Revit changes.

Installation

If you don't have another version of Twinmotion installed:

  1. Make sure you have the latest Revit update installed. You can download Autodesk Revit 2023 updates from your Autodesk Accounts, Products, and Services page or download and install automatically from the Autodesk Desktop Application.
  2. Starting with Revit 2023.1 update, the Twinmotion and Datasmith commands will be displayed on the View ribbon tab in the Presentation panel.
  3. Install Twinmotion for Revit, which also includes the Revit Datasmith installer. This can be accessed from your Autodesk Accounts, Products, and Services page. Locate Twinmotion for Revit from your list of products to access the installer.

Note: If you try to use the Twinmotion commands without first installing Twinmotion for Revit, you will be prompted to install Twinmotion. The Twinmotion is not installed dialog also includes the same link to your Autodesk Accounts, Products, and Services page.

If you already have another version of Twinmotion installed:

  1. Make sure you have the latest Revit update installed. You can download Autodesk Revit 2023 updates from your Autodesk Accounts, Products, and Services page or download and install automatically from the Autodesk Desktop Application.
  2. Download and install the latest version of Revit Datasmith installer.

The View tab shows the new Twinmotion ribbon button, which contains the new Open in Twinmotion command and the Datasmith commands.

Note: In Revit 2023.1 or later, the commands that were previously included on the Datasmith tab have migrated to the View tab, under the Twinmotion button.

Workflow

To launch Twinmotion and create a new direct link connection to the current Revit project:

  1. Open the Revit model.
  2. Click View Twinmotion Open in Twinmotion. This will launch Twinmotion and display a dialog with two options: New project and Existing project.
  3. Select New project.
  4. This will create a new Twinmotion project file and establish a direct link connection with the current Revit model. An initial synchronization is performed to send the geometry visible in the active Revit 3D view to Twinmotion. You can continue the design and visualization process in Twinmotion.
  5. As the design progresses in Revit, the latest changes can be sent to the Twinmotion project file by using the View Twinmotion Direct Link Synchronize. This will update the Twinmotion project file direct link with all recent changes from the Revit model, based on the active Revit 3D view.
Note: Once the Twinmotion project file is created, you don't need to click Open in Twinmotion again for the Revit project connected to Twinmotion, unless you want to create a new Twinmotion project with a direct link to the same Revit project.

To launch Twinmotion and open an existing Twinmotion project file without automatically establishing a new direct link connection:

  1. Open the Revit model.
  2. Click View Twinmotion Open in Twinmotion. This will launch Twinmotion and prompt with two options: New project and Existing project.
  3. Select Existing project.
  4. Browse to the Twinmotion project file and open it.

This will open an existing Twinmotion project file without automatically establishing a new direct link connection.

Notes:

To do a one-time export of the Revit model to a Datasmith format:

  1. Open the Revit model.
  2. Click View Twinmotion Export to Datasmith File.

    This command exports a file that can be imported in Twinmotion without setting up a direct link connection. This may be useful for scenarios where you prefer to import a file containing specific geometry into Twinmotion, Unreal Engine, or when you want to share a file with another design team.

To see the list of errors or warnings related to the export, click View Twinmotion Export Messages

To adjust the export settings, click View Twinmotion Export Settings.
