To understand why Dialux 3.14 was so pivotal, one must look at the landscape of lighting calculation software in the late 1990s and early 2000s. Before the widespread adoption of robust 3D calculators, designers relied heavily on the Lumen Method for manual calculations or used early 2D software that offered limited visual feedback. Before the widespread adoption of robust 3D calculators,
This eliminated the tedious task of redrawing room dimensions. A designer could take an architect's plan, import it, trace over it (or use it as a background), and immediately start placing luminaires.
