Learn how to Export .BIM files from Civil 3D

Written by Faisal Ramady

The 3D Repo for Autodesk® Civil 3D® plugin provides a convenient way of exporting your models from within the Civil 3D desktop applications.

Use this option if the model publisher fails to upload your model due to weak network bandwidth. Unlike with the model publisher, where the file is sent directly to 3D Repo, the model exporter will save a local version of the BIM file (3D Repo's proprietary file format). Upload the BIM file directly on our platform as shown here.

Currently supported versions: Civil 3D 2020, 2021 & 2022

Initial Setup

  • Download and install the plugin prior to opening Civil3D desktop application

  • Open your 3D model (.dwg) in Civil 3D

  • Once you have exported the BIM file, head over to and upload it there

We advise you to take measurements and check that your Civil 3D model matches the model units in 3D Repo.

Export .BIM files

  • Click on the Export icon located in the 3D Repo tab (main ribbon menu)

  • In the 3D Repo .BIM File Exporter window provide the following information:

    1. Model units (mm/cm/dm/m/ft). Tick the box to use the project units

    2. Choose the save location for your file

    3. Provide a name for the BIM file

    4. Select a Level of Detail (by default it is set to High)

    5. Click on the Export button

  • The progress bar will appear

  • Done will indicate a successful export
    A warning message will tell you otherwise

Great! Now that your file is ready, head over to and upload the model directly to a model container.
