Step 1 - Download and install Tobe Maps

Download and install Tobe Maps to your Android, or iOS device. If your device is not compatible with AR applications, it will notify you when you attempt to install Tobe Maps.

Step 2 - Login

Users can securely log in using their Microsoft AAD account from their operating company (CIMIC only). After logging in, they are directed to the project download and selection page, where they can choose the views for each of their projects. If you have logged in previously and have downloaded AR Views, you can select “Continue Offline” to work with your downloaded data only.

Buttons:

1. Sign In – Press to trigger the authentication flow

2. Operating Company Selection dropdown – Press to reveal the option

3. Offline Mode Button – Select this to continue offline if you have already downloaded and tested your required AR Views

- Select an operating company from dropdown

- Press the "Sign In" button

- Follow login steps in your browser

- Select “open” TobeMaps (iOS only)

- Press "Proceed"

Step 3 - Open an AR Project

The project menu is where you select and download AR Views. When you complete the login flow, a list of available projects will be shown.

1. Online indicator

2. Logout & Settings

3. Filter by DPI

4. Sort by

5. Project Search

6. Available Projects list

AR View Loading Workflow

- Select the Project folder to expand it and show AR views

- Select AR View

- Select models to download

- Press Download selected

- Enable properties (optional)

- Press the next arrow to load AR View

- Loading screen with safety disclaimer shown

- Press the Confirm button when loading is complete

Step 4 - Scan a marker

Calibration is required to accurately align the digital models with the real-world environment. This alignment is essential for providing an immersive and accurate augmented reality experience that aids in project planning, visualization, and communication among team members.

After loading the AR View the user is prompted to:

- Scan environment until required tracking confidence is achieved

- Select calibration method: Image Targets or Manual

Users can print and place the universal image target at configured within the project site. TobeMaps then uses these targets to localize and align the virtual reference frame with the real world.


Select “Image Targets”

Scan target until 100% tracking confidence is reached (you can continue with less than 100%)

- Press Next (Right Arrow button)

- Select the image target from the map view (move map as required)

- Press next to complete the calibration

Step 5 - Using the AR Viewport

1. Calibration

2. Quick Adjust

3. BIM Hierarchy

4. Screenshot button

5. Properties Inspector

6. Utilities

7. World Space Tools

8. Map-AR View toggle

9. BIM Visibility

10. Global transparency slider

11. Map and Model transparency sliders

Step 6 - Map View

The Map View allows you to view where you currently are in relative to the model and map. It also acts as a BIM viewer with simple BIM interaction tools such as transparency, BIM hierarchy and Properties.

To enter Map View press the “View toggle” button.

1. Camera Type (Orthographic or Perspective)

2. Camera controls (Map or 3D Viewer)

3. Map Type selection

4. Show/hide image target locations

5. Show All transparency sliders

6. Global Transparency Slider

7. Model Visibility

8. Toggle View (Map or AR)

9. Centre map on device current position

Map Contols

• Single touch & drag to pan

• Pinch to zoom

• Twist to rotate

• Two finger swipe up to view 3D

Step 7 - BIM Hierarchy

The BIM hierarchy feature in TobeMaps provides a structured way to navigate and interact with the BIM. It organizes the model elements based on their relationships and categories, such as architectural, structural, or MEP systems. Users can easily expand and collapse the hierarchy to locate specific elements or groups within the model.

By interacting with the BIM hierarchy, users can control the visibility of elements in the scene. They can show or hide specific elements or entire categories by toggling their visibility on or off. This enables users to focus on relevant parts of the model, reducing visual clutter and allowing for more efficient analysis, coordination, and problem-solving.

- Press hierarchy button to show Hierarchy

- Click drop-down button on each model to expand is hierarchy

- Press the “eye” button to toggle visibility

Step 8 - Properties Inspector

The Properties Inspector allows users to access and view the properties of model elements in both the Map and AR view. By simply tapping or selecting an element, the Properties Inspector displays relevant information such as dimensions, material, and other attributes associated with that element.

This feature enhances the AR experience by augmenting the real world with rich information about the model elements. As users explore the project site in AR view, they can easily query the properties of specific elements, allowing them to make more informed decisions and better understand the project's details.

- Press “Inspector” button

- Highlight model element by moving the device until it is highlighted by the reticule

- Tap anywhere on screen to select an element and view its properties

- Expanded properties will remain expanded for subsequent selections that have the same properties

Step 9 - Pit & Measure Tools

The Pit and Measure tools are essential features in construction and design applications, providing valuable insights for project teams.

Pit Tool: The Pit tool is designed to allow users to simulate and visualize excavation, earthworks, and foundation elements within a project. By creating a virtual representation of the pit, users can examine the impact of the excavation on surrounding structures and utilities. This helps identify potential issues, streamline construction planning, and improve overall project coordination.

Measure Tool: The Measure tool enables users to accurately measure distances, areas, and volumes within the project. By selecting points or elements within the model, users can quickly determine critical dimensions, such as the distance between two structures or the size of a specific component.

Step 10 - Draw Distance and Depth Occlusion

Draw distance is a feature in TobeMaps that allows the user to adjust the distance at which 3D models are rendered in the AR view. This feature is important because rendering too many models at once can cause the app to slow down, making it difficult to navigate the scene. By adjusting the draw distance, the user can improve app performance while still being able to view important models.

Depth occlusion, also known as occlusion culling, is an experimental feature in TobeMaps that attempts to integrate the physical environment with the digital content in the AR view. This means that if there is a physical object in the real world that should block the view of a digital object, the digital object will be hidden from view. This feature can provide a more immersive experience for the user, but may cause some visual distortion or shimmering in certain situations.
