How to Add a New Surface to an Existing Project

Introduction

A project file can hold multiple design surfaces (TIN, plane, or alignment-based). Adding a new surface allows you to switch between design options or work stages without starting a new project.

⚠️ Safety Notes

  • 🔴 Only load files from trusted surveyors/engineers — incorrect design data can cause grading errors.

  • ⚠️ Do not change files during digging — always load new data when the machine is stopped and safe.

  • ✅ Keep files organized — avoid duplicate names to prevent confusion.

Step-by-Step Instructions

  1. Insert USB flash drive

    • Save the new surface file (TIN .TN3, Plane .PL3, or Alignment .RD3) to the root directory of a USB stick.

    • Insert the USB into the ICT monitor port.

  2. Open File Menu

    • On the ICT monitor, tap Menu → File → Design Data.

    • The current project file list will appear.

  3. Import the new surface

    • Tap Input.

    • Select Import from USB.

    • Highlight the new surface file from the list (e.g., Pad_Design.TN3).

    • Tap the checkmark to import.

  4. Assign the surface to your project

    • Once imported, the surface will appear under the current Design Data list.

    • Highlight it and tap Change Active if you want to make it the working surface.

    • If not, it will still be stored in the project for later use.

  5. Confirm settings

    • Go to File → Active Design Data.

    • Ensure the correct project file is active, and select the new surface as the Active Surface.

  6. Verify on screen

    • Return to the main view.

    • The new surface should now be shown on plan/profile screens for iMC guidance.

Tips

  • Use clear names for surfaces (e.g., “Final_Grade”, “Subgrade_300mm”) so operators know which one to select.

  • You can store multiple surfaces in one project and switch between them depending on the task.

  • If you get an error like “Surface: Too Dense”, the file may need simplification by your surveyor.

Conclusion

Adding a new surface to an existing project is simple: import it via USB, assign it within the project, and select it as the active design. This flexibility helps operators adapt quickly to new design updates on site.
