Installing the Extension

1. Download the latest Geotechnical Modeler Microsoft installer (MSI) file.

4. Once the installation has finished close out of the installer wizard.
5. Open Civil 3D 2023.

The first time Civil 3D is opened after installation of the tool the InfoCenter should display a notification balloon to alert you that: “Geotechnical Modeler has been added to Civil 3D”.

Note: To confirm installation files have been copied to the correct folder, you may look for the C3D-GeoTechModeler-2023 folder in the Windows Program Data directory located here: C:\ProgramData\Autodesk\

Starting the Extension

Once the Geotechnical Modeler installation is complete, you may run the tool from the newly installed ribbon tab.

You can also access the Geotechnical Modeler tools, commands, and dialog boxes by using the command line. To get started, enter the command GM_ManageData to create a new project and import data.

Troubleshooting Installation or Startup Errors

If the installer fails or the tool fails to start, make sure to fully uninstall any previous versions of the Geotechnical Modeler.

You can manually uninstall the Geotechnical Modeler by deleting the C3DGeoTechModeler-2023 add-on folder located here:

• C:\ProgramFiles\Autodesk\ApplicationPlugins\C3D-GeoTechModeler2023.bundle

The supporting files can be uninstalled by deleting the Lithologic Patterns and Template Drawing folders located here:
