# 4.3 | Loading or Creating a Project

## Loading a Design File

To load a design file, press **Done** at the top-right to return to the **Level COMMAND** apply page, then press **More** > **Load Project.** This will open the Change Project page and display all .tad file projects. This file type is specific to LC and the software will automatically scan the file system to find all .tad files present - alternatively to find them manually press "**Browse**" on the right side of the screen.

**Supported design formats:**

• T3RRA Project (.tci)  
• GPS Design (.gps)  
• Existing Level COMMAND Plane Projects

### Loading an External Design File (Other File Types)

If loading a design of different file type, such as .tci, press "**To Import**" to move to the Import Data page. Select the design file from the list and then press "**Import Selected**".

## Creating a Basic Plane Project

A Plane project is the quickest way to begin using **Level COMMAND** without importing an existing design. Plane projects are commonly used for machine testing, simple levelling work and creating flat pads. To create a basic 2D/3D plane project, begin by pressing **More > Start Plane**. Choose an appropriate location to save the plane project on the tablet PC and then name the project, then press "**Save**".

To begin designing a Plane:

1. Press **Planes**, then select one of the available Plane slots.
2. Press **Create**.
3. Press **Origin** and then **Use GPS** to set the Plane origin to the current implement position.
4. Press **Okay** to create a flat Plane surface.

The Plane can now be loaded and used for testing or levelling work.

If a sloped surface is required, press **Slope** and use **Use GPS** at a second location to automatically calculate the desired slope.

For detailed information on Plane projects, refer to **Section 5 | Operational Workflows**
