The idea was never the bottleneck in early design. The hard part is showing it fast.
D5 Lite brings AI visualization directly into SketchUp, Rhino, and Revit, so you can go from a concept model to a shareable visual without leaving your modeling tool. With CLI control, AI agents like Codex, Claude, and D5 Arco can also run supported visualization tasks in D5 Lite.
Join the Grey to Great Challenge and bring your ideas to life with D5 Lite. Take a model, transform it with D5 Lite, and show us your Before → After.
Every valid entry gets a 7-day D5 Pro trial. 
Standout entries win 45 days of D5 Pro and a feature on D5’s global channels.
