Klayout 25d View -

Click the "Run" button in the macro IDE. A new 2.5D window will appear, rendering the section of the layout currently visible in your main viewer. Navigation and Controls

The 2.5D view respects your 2D layout settings. If you change a layer's fill color or hide it in the main viewer, it will update in the 2.5D window.

Currently, the tool has a practical limit of approximately 100,000 polygons . Setting Up Your First 2.5D Scene

Navigate to Tools > 2.5d View > New 2.5d Script . This opens the macro editor with a template based on the Design Rule Check (DRC) language. Click the "Run" button in the macro IDE

To use this tool, you must provide a that defines the "material stack"—essentially telling KLayout which layers to extrude and to what height.

Unlike a true 3D viewer that might support arbitrary angles and curved surfaces, the 2.5D view in KLayout works strictly by taking 2D polygon layers and extruding them vertically. It cannot model complex process topologies (like conformal coverage) but excels at showing how different metal, poly, and diffusion layers sit on top of each other. Key Technical Requirements If you change a layer's fill color or

Because semiconductor layers are often very thin relative to their width, the 2.5D view includes a on the right side of the window. Increasing this factor exaggerates the vertical dimensions, making it easier to see height variations that would otherwise appear flat. Advanced Visualization Features
