Pro tip: Adjust the “height” factor in layer properties to exaggerate thickness for better visibility.

The Concept: What is "25D" in KLayout?

In the context of Electronic Design Automation (EDA), "25D" (or 2.5D) refers to a visualization method where 2D polygons are extruded vertically based on a assigned "height" and "thickness." Unlike a true 3D engine that accounts for physics, deposition, and etching angles, KLayout’s 25D view is a geometric extrusion.

• Provide step-by-step instructions for your KLayout version.
• Create a sample layer-height configuration file.
• Show keyboard shortcuts and UI paths for common actions.

Thus, the 2.5D view complements—not replaces—traditional DRC, LVS, and parasitic extraction workflows.

Colors/Visibility: The 2.5d view inherits colors and visibility settings directly from your active Layout View.  Navigation Controls  Action  Rotate (Azimuth/Elevation) Drag with Right Mouse Button Move Pivot (X/Y/Z) Drag with Middle Mouse Button Pivot Forward/Backward Mouse Wheel Zoom Layout Ctrl + Mouse Wheel Snap to Top View Hold Shift Key Provide step-by-step instructions for your KLayout version
