Installation

System requirements

• AutoCAD 2025 or later, or Civil 3D 2025 or later
• Windows 10 or later (64-bit)

Installing

1. Download the R3Survey installer from mitchellsurveying.com.au/r3survey.html
2. Close AutoCAD / Civil 3D before running the installer
3. Run the installer and follow the prompts — you may see a Windows SmartScreen warning, click More info then Run anyway
4. Open AutoCAD or Civil 3D — when prompted with an "Unverified Publisher" security dialog, click Always Load to allow the add-in to load

The installer places the add-in bundle in the standard AutoCAD plugin folder so it is loaded automatically on startup.

Licence

No activation is required for the beta release. The licence is included in the installer. Use R3ABOUT to confirm the licence is loaded and to view the expiry date.

Uninstalling

Use Add or Remove Programs in Windows Settings and remove R3Survey. This will remove the bundle files but will not remove any drawing data or settings files.

Updating

Use the R3UPDATE command from within AutoCAD or Civil 3D to check if a newer version is available. If an update exists, download and run the new installer — it will replace the existing installation.
