25d View — Klayout

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.

It helps junior designers understand the physical reality of the fabrication process—reminding them that layouts aren't just drawings, but physical stacks of material. klayout 25d view
