Introduction

The BIM Compare View allows you to compare BIM models alongside 360° captures, offering a clear visual reference for project analysis. You can navigate the Capture Viewer with the BIM Viewer, use the BIM Selector to manage multiple models, and switch between different compare modes. Additionally, support for Revit 3D views and Navisworks viewpoints ensures compatibility with familiar workflows.

Accessing BIM Compare View

To start a BIM comparison:

1. Open your project in SiteView and access the menu on the left side.
2. Click BIM Compare in the menu.

This opens the Capture Viewer alongside a synchronized BIM Viewer, allowing you to compare the 360° panos and BIM model side by side.

Navigation in BIM Compare View

By default, the BIM Viewer is synchronized with the Capture Viewer. You can navigate the Capture Viewer in the following ways:

• Click inside the viewer or use the WASD keys or arrow keys to move.
• Navigate directly to a specific location using the Plan Viewer or Location Indicator.

Note: For more details, refer to the Navigation in First Person Mode article.

When switching to Aerial Mode, the BIM Viewer also transitions to Aerial Mode, synchronizing with the 3D Dollhouse or Imported point cloud in the Main Viewer.

Note: For more details, refer to the Navigation in Aerial Mode article.

BIM Selector

The BIM Selector allows you to load, overlay, and manage multiple BIM files and predefined views.

1. Click Change in the BIM Selector.
2. Toggle BIM model(s) on or off to control which models are visible in the viewer.

Note: If the BIM model includes published Revit 3D Views or saved Navisworks Viewpoints, you can display them in the BIM Viewer by toggling them on.

• Revit 3D Views – Synchronize and display predefined 3D views from Revit.
• Navisworks Viewpoints – Retain and visualize predefined viewpoints from Navisworks.

Changing Compare Mode

You can switch between different compare modes in BIM Compare View:

• Dual Camera: Traditional side-by-side comparison
• Single Camera: Overlapped views with a slider to reveal portions of each environment
• TwinLens: A movable window displaying a second 360° virtual tour or BIM overlaying the primary view

Note:
In BIM Compare View, you can switch between compare modes while using different view modes, including both First-Person Mode and Aerial Mode.
For more details, refer to the Change Compare Mode article.

Options

Default Options

When the BIM Viewer is synchronized with the Capture Viewer, the following options are available in the top menu:

1. Transport – Appears when an object is selected, allowing you to overlay one or more objects onto a pano or point cloud in the Capture Viewer.
   Note: For more details, refer to the Overlay and Transform BIM Objects in BIM Compare View article.

2. Measure Distance – Enables measuring distances, angles, and calibrating between points.

3. Add X-Y-Z and Box Clipping Planes – Adjust the BIM model’s plane to show or hide objects on different planes.

4. Model Structure – Toggle specific object types on and off to isolate elements within the BIM model.

5. Properties – View details such as constraints, material types, costs, and dimensions for selected objects.

6. Settings – Configure the BIM Viewer, including navigation, appearance, and environment settings.

7. Filter Visibility – Show or hide pano bubbles in the BIM Viewer.

Options for Unsynced Mode

Right-click and select Unsync Camera to freely explore the BIM model without following the Capture Viewer’s movement. Once unsynced, additional options become available:

• Fly Mode – Navigate the BIM file in first-person view.
• Orthographic/Perspective Views – Switch between orthographic and perspective viewing modes.
• Reset View – Return to the original view.

Right-Click Options for Selected Objects

Right-clicking in the BIM Viewer provides various interaction options:

• Select Shown – Select all visible objects for transport.
• Show All – Reveal all previously hidden objects.
• Show Properties – Display details of the selected object.
• Search by Properties – Find and select BIM objects that match the entered property name or value.

Additional options when object(s) selected:

• Isolate – Hide all objects except the selected one.
• Hide Selected – Hide the selected object(s).
• Hide Unselected – Hide everything except the selected object(s).
• Focus – Zoom in on the selected object(s).
• Transport Selected – Move selected objects to Capture Viewer.

Note: You can select multiple objects by holding SHIFT while clicking on them. To deselect all objects, press ESC.
