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 engineer fixes it in minutes, rather than hours of cross-probing between schematic and layout. klayout 25d view

Your specific (e.g., CMOS IC design, MEMS, Silicon Photonics)? The file format you are using (GDSII or OASIS)?

: It is currently optimized for sections of a layout, with a practical limit of roughly 100k polygons . You must define the thickness and z-position for

Instantly spot vertical overlaps, missing vias, or incorrect layer order that standard 2D Design Rule Checking (DRC) text logs might obscure.

Draw a cut-line across your 2D layout. The tool will parse your layer stack script and generate a highly detailed vertical 2D cross-section. Right-click + Drag: Pan across the layout

Each layer can be assigned an arbitrary height in the Z-dimension. By default, layers are extruded uniformly, but advanced users can script relative heights to mimic real dielectric thicknesses.

: The current implementation handles approximately 100,000 polygons before performance significantly degrades. How to Use the 2.5D Viewer
