Everything looks like flat colored paper. Solution: You forgot to set the "Height" in Layer Properties, or you haven't tilted the camera (still in top-down orthographic mode).
By spending 10 minutes configuring your layer heights and learning the camera controls, you transform KLayout from a static plotting tool into a dynamic visualization engine. Whether you are verifying a MEMS device, a Silicon Photonics chip, or a standard CMOS block, the "2.5D view" brings your layout to life—literally lifting your polygons off the screen to reveal the true vertical complexity of your design. klayout 25d view
