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 It cannot model complex process topologies (like conformal
The script uses a syntax similar to Design Rule Check (DRC). :
: Useful for visualizing advanced packaging structures like silicon interposers that connect multiple dies. 5D script for a specific process like Sky130 ? Colors in the 2.5d View - KLayout Layout Viewer And Editor
