Dialux 3.14

Dialux 3.14 — Complete Guide & Practical Tips

Overview

Dialux 3.14 is a version of the DIALux lighting design software family used by lighting designers, architects, and engineers to plan, calculate and visualize interior and exterior lighting. It supports photometric data, realistic renderings, standardized calculations (lux, luminance), and reports suitable for project documentation and compliance with lighting standards.

While "3.14" is not a current primary version—as the software has evolved through DIALux 4 (the classic version) and into the modern DIALux evo—the platform continues to provide comprehensive tools for precise illumination engineering.  Core Capabilities  Dialux 3.14

4.2 Outdoor Lighting

• Street lighting (calculation of average luminance L, overall uniformity U0, threshold increment TI according to EN 13201)
• Parking lots and pedestrian zones

• The "Copy Along Path" Tool: Select a luminaire, right-click, "Copy along polyline." Create perfect curved lighting rows. Evo still struggles with this.
• The Colour Rendering Index (CRI) Visualiser: While evo has true colour, 3.14 had a "False Colour" overlay that instantly showed illuminance uniformity (Emin/Eavg) in a heat map. It was faster than any modern plugin.
• Emergency Lighting Assistant: A dedicated button for placing emergency exit signs and calculating spacing in accordance with BS 5266-1. Many users kept 3.14 solely for this feature.
• The "DXF Out" Filter: You could export a photorealistic 3D wireframe of your lighting plan back to CAD, preserving layers (LUMINAIRE, FURNITURE, WALL). This workflow is broken in evo.
