Describe It. Get Editable CAD.
Nora3D is AI CAD software that turns plain language into editable, parametric B-Rep models — not static meshes. Generate a solid in seconds, refine it like real engineering geometry, and export STEP, STL, IGES, or OBJ for 3D printing and manufacturing.
Supported Devices
Real CAD from Natural Language,
Not Just Mesh Generation
Most AI 3D tools stop at a static mesh you can barely change. Nora3D generates editable B-Rep solids with verified geometry — so every model can be dimensioned, refined, and exported into real engineering and 3D printing workflows.
Text to Editable CAD in Seconds
Describe the part in plain language — size hints, features, constraints — and Nora3D turns your intent into an editable parametric solid, not a frozen mesh.
Verified, Iterative Geometry
Generated models are checked for wall thickness, clearances, and manufacturability. Say "taller wall" or "switch to M6 holes" and the same model evolves — no regenerating from scratch.
CAD Anywhere: Web / Tablet / Phone
Start when the idea hits, not when you're back at a workstation — sketch on your phone, refine on your tablet, export STEP or STL from the browser. One synced workspace.
Text to CAD with STEP and STL Export
Describe your part in plain language, generate an editable solid, then export STEP to continue in SolidWorks or Fusion 360 — or STL straight to your slicer.
AI Semantic Modeling
Describe what you want to build and get editable CAD — no feature trees to fight, no complex setup.
Component Library Smart Search
Quickly find printable standard components like brackets, clips, and enclosures.
Multi-device Collaboration
Start a design on your phone, refine on tablet, and export on desktop — all synced in real-time.
Import STEP / STL
Import existing STL or STEP files, modify for better printability, and re-export.
Lightweight Rendering Preview
Preview your print in real-time to catch issues before slicing.
AI Hand Drawing
Sketch part outlines by hand on mobile — AI converts them into precise, printable geometry.
Three Steps to a Real Part
From idea to editable CAD to export
Focus on what you want to make, not how to operate the software
Describe Your Part
Tell Nora3D what you want to make in plain language — or sketch it by hand
Generate & Refine
AI builds an editable solid in seconds — keep refining it with prompts or precise CAD tools
Export and Make
Export STL directly to your slicer, or STEP to continue in SolidWorks or Fusion 360.
One AI CAD Workspace
For Everyone Who Makes Things
Functional prints, product concepts, jigs and fixtures, classroom projects — Nora3D turns intent into editable CAD, so the tool never gets in the way of the idea.
3D Printing Makers
Design custom parts, organizers, and functional prints — tune wall thickness and clearances, then export STL straight to your slicer.
Product Designers
Explore concepts at the speed of conversation — generate variants in seconds, refine the best one, and hand off real STEP files.
Engineers
Draft jigs, fixtures, and mechanical parts from requirements — import existing STEP files, iterate with AI, and export back into your toolchain.
Education & STEM
Students describe a part and watch it become real CAD — spatial reasoning and design thinking without a semester of software training first.

Editable CAD vs
Mesh Output
A model you can't edit is a screenshot, not a part. Nora3D outputs editable B-Rep CAD — dimensions, features, and tolerances stay live — while mesh generators leave you with frozen triangle soup.
Nora3d – Editable B-Rep CAD
- Modify dimensions and features precisely
- Export STEP for SolidWorks and downstream tools
- Production-ready for manufacturing
Mesh-based AI 3D Tools
- Hard to edit dimensions after generation
- Visual-only output, limited CAD compatibility
- Not suitable for engineering or manufacturing
