# Installation GeoDin® Ground is distributed as a free plug-in on the **Autodesk App Store**. The installer adds a **GeoDin® Ground** ribbon tab to Civil 3D with all plug-in commands. ### Prerequisites * **Autodesk Civil 3D 2025** or **Autodesk Civil 3D 2026** installed and licensed. * **A GeoDin® database** containing the boreholes you want to visualise. The database can be a file-based Microsoft Access file (`.mdb` / `.accdb`) or a client/server database connection already configured in GeoDin®. * *(Optional)* GeoDin® itself installed on the same machine — useful for editing the underlying records, but not required to run GeoDin® Ground against an existing database. > **No database yet?** The plug-in installer ships with a **Denver** sample database you can use to explore every command. It is also downloadable directly: > > {% embed url="" %} ### Download and install the latest version {% embed url="" %} 1. Open the Autodesk App Store and search for **GeoDin® Ground** (or use the link above). 2. Download and run the installer. 3. Start or restart Civil 3D. 4. A new **GeoDin® Ground** ribbon appears in Civil 3D. If you do not see it, confirm you installed against the Civil 3D version you actually launch, then restart Civil 3D. ### Running fully offline GeoDin® Ground can run without any network connection. If your security policy requires it, place the `.accdb` file on the local hard drive, install Civil 3D and GeoDin® Ground on the same machine, and disconnect from the network. Every command described in these docs works in that configuration. ### Next steps Once installed, continue with [First steps](/geodin-ground/getting-started/first-steps.md) to connect a database, load boreholes, and draw your first ground model. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
