Klayout 25d View |best| Jun 2026

Eliminates the tedious process of exporting to external 3D modeling engines.

Unlike a simple 3D toggle, generating a 2.5D view in KLayout requires a . This gives you immense control to define the material stack precisely.

Because the height is assigned by layer, if a polygon exists on a layer, it is extruded to that height globally. If a designer manually draws a shape that should be on a different vertical plane (e.g., a metal jump), the 25D view will render it incorrectly unless it is moved to a different GDS layer number. The visualization is data-dependent, not context-aware.

If you have not set up a layer stack, KLayout will prompt you to define one. You must specify: Eliminates the tedious process of exporting to external

Master KLayout 25D View: The Ultimate Guide to 2.5D Semiconductor Visualization

In KLayout—the popular open-source GDS/OASIS viewer and editor—the 2.5D view is a hybrid visualization mode. Unlike a true 3D rendering (which simulates physical topography), 2.5D projects each layer vertically to create a pseudo-3D extrusion effect. Layers maintain their planar coordinates but are offset in the Z-axis, giving the illusion of stacked physical planes. If you have not set up a layer

Within the 2.5D viewer, you can define how much each layer is "extruded" in the vertical dimension, enabling you to represent the dielectric stack thickness.

Fix: Your elevations are likely set to 0, causing all layers to flatten into each other. Double-check your z-start values. Alternatively, hit the "Fit to View" button to center the camera. Fix: Check your math. If Metal1 ends at , your Via1 layer must start exactly at Performance Lag on Large Designs:
