Klayout 25d View [better]

Objects flicker or have gaps between them. Solution: This is "Z-fighting" (two layers at exactly the same height). Set a micro offset (e.g., Metal1 height 30, Via height 30.001). Alternatively, lower your screen's anti-aliasing settings.

The 2.5D view in KLayout is a pseudo-3D visualization tool. It takes 2D layout geometries (GDSII or OASIS files) and extrudes them vertically based on a defined layer stack. 2.5D View vs. True 3D View klayout 25d view

Once you're in the 2.5D view, the interface shifts to a camera-centric navigation system: (Azimuth/Elevation) Right Mouse Button (Move Pivot) Middle Mouse Button (Pivot Forward/Back) Mouse Wheel Magnify/Shrink Ctrl + Mouse Wheel Reset to Top View Performance and Practical Limits Objects flicker or have gaps between them

This allows batch processing of multiple layout versions, each with a standardized 45° tilt and lighting setup – perfect for regression visual diff testing. Alternatively, lower your screen's anti-aliasing settings
