You must define the thickness and z-position for each layer in the layer properties. Left-click + Drag: Rotate the view. Scroll Wheel: Zoom in and out. Right-click + Drag: Pan across the layout.

The most critical prerequisite is that your version of KLayout must be and your hardware must support it. This is because all 3D rendering is handled via OpenGL. If you've built KLayout from source and the 2.5D view option is missing from your "Tools" menu, a missing OpenGL dependency is the most likely culprit. Using a pre-built binary from the official KLayout website is the safest way to ensure this feature is available. klayout 25d view
Essential for visualizing waveguiding paths and suspended sensor structures. How to Set Up the 25D View in KLayout
According to the official KLayout documentation , the provides a semi-3D representation of a layout. It is important to understand that this is not a full 3D rendering engine; it does not model complex physical process topologies, such as tapered vias or surface curvature (non-planarization). You must define the thickness and z-position for
: 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.
Inside the 3D View pane, look for the camera icon or the dropdown menu. Ensure the view is set to (not Orthographic). Perspective gives you the "vanishing point" effect, making the depth look realistic. Right-click + Drag: Pan across the layout
The 2.5D view isn't just a "one-click" magic button; it requires a bit of configuration to know how high to extrude each layer. Check Requirements : Ensure your version of KLayout is compiled with OpenGL support
This is where the —often called "2.5D"—enters the workflow. In KLayout, the 25D view is not merely a cosmetic gimmick; it is a critical analytical tool that provides depth perception, vertical layer relationships, and structural intuition without the computational overhead of full 3D modeling.
KLayout is a popular, open-source, and powerful tool for viewing and editing layout files, particularly in the semiconductor industry. The 25D view in KLayout refers to a specific way of visualizing 3D structures from 2D layout data, offering insights into the third dimension (height or depth) through the use of color and layer stacking. This guide aims to cover the basics and advanced features of using KLayout for 2.5D (or 25D) viewing:
