Downloading your data

iTwin

iTwin is currently supported through their .bim snapshot format. Please consult your application's documentation and support for how to get a snapshot from your data. It is not always possible without using a developer tool.

Please contact support if you are interested in a tool to download any iTwin as a snapshot, but be aware that you will need to sign up for an iTwin developer subscription to use it.

You can also create a snapshot iModel/iTwin from many source data file types using iTwin's free tool.

Synchro 4D

In Synchro 4D, you can do the following to download a .bim file of your project:

  1. You will need a Bentley account and internet access, as the export will run in the bentley infrastructure cloud.
  2. Navigate to the Export > 3D option, and select the .bim format.
  3. Tweak the settings in the menu as you see fit and be sure to export animation if you want animation.
    Export 3D Bim Menu with Export Animation option selected
  4. You should now have a .bim file that you can open with Twin Sync Studio!

Other

You can create a snapshot iModel/iTwin (.bim) from many source data file types using iTwin's free tool.

Supporting other data sources where possible is under consideration and please feel free to contact support with any requests.

Access keys and installations

To successfully install Twin Sync Studio, you will need:

System Requirements

To successfully use Twin Sync Studio, you will need at least:

  • Unreal Engine
  • A workstation with a non-integrated graphics card (GPU).
    Nvidia 2000 series or better is recommended. The more VRAM, the larger scenes you'll be able to handle.
  • Windows 10 or 11. If you need another operating system, please contact support.
  • At least 16GB of CPU RAM

Installation

To successfully install Twin Sync Studio, you will need:

  • The downloaded installer
  • An access key

Both of the above should be delivered promptly to your registered email (within 1 business day) after payment is processed.

Once you have both, on Windows:

  1. Double click the downloaded installer
  2. If you are greeted by a blue "Windows protected your PC" window, hit the "more info" link and then the "run anyway" button.
    Since Graphl Technologies LLC is a new company with a new code signing certificate, (April 2025), you may see this screen until the application has been downloaded many times. See this link for more details.
    Regardless, always check that the installer was signed by Graphl Technologies LLC, as indicated by Windows as you run it.
  3. Read through the End-User-License-Agreement, terms and conditions, and privacy policy.
  4. Press "accept and continue" if you agree and are ready to proceed.
  5. Type or paste your access key into the text input, and press "submit".
  6. If your license is valid (you have installed on this machine before or have unused installations on your license), then Twin Sync Studio should open! Of course, if it doesn't work, please contact support with the given error message.

Updates

Please refer to the terms of sale of your purchase for full details. Typically, Twin Sync Studio is sold with a 3-month update period, during which you will be notified of new updates and you will be allowed to download new versions.

After your update period ends, if you do not purchase a new support subscription, your perpetual license takes over and attempting to install newer versions will be rejected.

If you lose the installer for the version you have a perpetual license for, you may request it from support. Unless you requested the removal of your data, we keep track of the when your support ran out and can give you the latest version to which you are entitled by your purchase agreement.
