Use the Slice tool 
to reveal occluded content in a scene. The Slice tool hides any layers or terrain the slice intersects. For example, you can slice a building to display inside layers, such as interior walls and furniture.
Create a slice
To create a slice, do the following:
- Click Analyze
to access the Slice tool . - Click the Slice tool.
- Click New Slice.
- The tool indicates where the scene will be sliced.
- Press Ctrl (or Command) or Shift while clicking to slice with either a horizontal or vertical plane, respectively.
- Click a surface or object to make a slice.
The slice hides any content in front of the surface.
- Drag the handles of the slice plane to move, resize, or rotate the slice.
- Click New Slice again to start another slice.
- Close Analyze to hide the slice.
- Click the Slice tool again for the slice to reappear in the scene.
Exclude layers
After a slice is created, you can exclude layers from the slice. For example, you can set the HVAC and windows layers in a building to remain visible while you slice.
- Click Exclude Layer from Slice.
- Click a layer in the scene to exclude it from the slice.
The layer is added to the Excluded layers list.
- Click Cancel to return to the initial view.
- Click Exclude Layer from Slice again to make another layer visible.
- Click the Remove button
next to the layer name to remove it from the Excluded layers list.
Interact with a slice
Once you've created a slice, you can explore and examine your scene further with Scene Viewer tools, such as the Pop-ups and Measure tools. For example, you can measure the length of an HVAC air duct inside a building that was previously hidden.
