Turn rough sketches and descriptions into 3D models in minutes — no CAD experience needed.
Free to start — no card required
Built for you
No CAD training required. HarmonyCAD handles the complexity so you can focus on your design intent — perfect for coursework, prototypes, and final year projects.
Prompt to print-ready in minutes, not days.
Time calculator
Based on our benchmark: each design takes ~4 hours in Fusion 360 and ~4 minutes in HarmonyCAD.
That's 11.8 hours back every week — 77 full working days a year.

Merlin automatically inspects your models for weak points, printability issues, and functional flaws. Get clear, actionable guidance so every design is ready for the real world. Explore the full product to see Merlin in action.
Stories, decisions, and thinking from the team building HarmonyCAD.
The idea was clear. The software was not. Here's the story of why HarmonyCAD exists — and the gap in the market it was built to fill.
Fusion 360 isn't the answer for creatives. Here's why traditional CAD tools fail the people who need 3D the most — and what they actually need instead.
The way hobbyists design custom parts is changing fast — and many are doing it without ever touching traditional CAD software.
