This "pseudo-3D" visualization is incredibly powerful for several reasons:

The 25D View is a specialized visualization mode in KLayout that projects 2D layout shapes into three dimensions by applying thickness and height values to specific layers.
: The viewer works best for small areas (around 100k polygons max). If your layout is huge, zoom into a specific "piece" or area before running the script. Navigation : Right-click + Drag : Rotate the view. Middle-click + Drag : Pan. Mouse Wheel : Zoom. If your layout is huge, zoom into a
When explaining a layout to colleagues or in a design review, the 2.5D view provides a much clearer narrative than dozens of 2D layer screenshots. It helps non-layout experts (e.g., circuit designers) quickly grasp the physical topology.
