KLayout operates primarily as a GDSII, OASIS, and DXF file viewer. In standard operation, it renders layout data as flat, 2D polygons on distinct layers. However, modern semiconductor processes involve complex vertical topologies. The "2.5D View" (often referred to as the "3D View" or "Cross-Section View" within the software) bridges the gap between flat 2D plans and physical 3D realization. z(input(1, 0), zstart: 0
You can rotate, pan, and tilt the view interactively. This makes it easy to inspect via stacks, overlapping geometries, and potential spacing violations that might be invisible in pure top-down mode.

Ensure your layers have distinct colors and transparency settings in the Layer Toolbox; the 2.5D view inherits these styles.
