This is the most critical distinction. KLayout’s 25D view is . It does not simulate:

Disable dummy fill layers or text layers before launching the 2.5D view.

Share intuitive, spatial representations of complex device architectures with team members, fabricators, or clients who may struggle to interpret flat mask data. klayout 25d view

Mastering the KLayout 2.5D View: A Comprehensive Guide to IC Visualization

This makes the 25D view exceptionally fast—almost as responsive as 2D—while conveying 80% of the spatial insight of a full 3D engine. This is the most critical distinction

Once rendered, KLayout opens a separate display window containing the pseudo-3D representation of your layout. You can interact with the model using the following controls:

: It helps visually confirm that vias are correctly spanning the vertical gaps between metal layers. You can interact with the model using the

Once installed, a new menu option will appear under > 25D View (or via a dedicated icon on your toolbar). Clicking this opens a split-screen or secondary window displaying your layout transformed into a rotatable, three-dimensional space. Configuring Layer Properties (The Z-Stack)

Unlike a true 3D CAD model that uses complex solid geometries, a 2.5D engine extrudes flat polygons vertically. It assumes the shapes have straight, vertical sidewalls. This technique provides a clear view of layer interactions, vias, and step coverages without lagging your computer. Key Benefits for IC Designers

Assign distinct colors to Vias (e.g., bright yellow) and Metals (e.g., deep blue or copper red) to quickly spot alignment errors.
