Building with CAD AI — Next-Generation Design Tools for Architects


Here's what CAD AI (cad.aiconcept.art) does in 30 seconds: you type "gear 20 teeth module 2", hit Generate, and get a parametric 3D gear model ready for export to STL, OBJ, or DXF. No desktop software. No license fees. No installation.


That's the MVP. This guide walks through what exists now, what's coming in Q2, and where CAD AI fits in a working architect's stack.


What You Get Today (MVP Phase)


Browser-Based OpenSCAD Compilation

CAD AI runs OpenSCAD WASM directly in your browser. Write parametric code or use keyword generation, compile to 3D models client-side. Your design data never leaves your machine until you choose to export.


Three.js 3D Viewport

Real-time 3D preview with orbit controls, zoom, pan. Rotate your models to inspect geometry before export.


Multi-Format Export

  • STL for 3D printing
  • OBJ for rendering software
  • DXF for 2D CAD tools
  • PNG screenshots for presentations

    • Keyword-Driven Generation (Phase 1)

    Simple mechanical parts from text:

  • `cube 50 50 50` → 50mm cube
  • `cylinder h=100 r=25` → 100mm tall cylinder, 25mm radius
  • `sphere 30` → 30mm radius sphere
  • `gear teeth=40 module=1.5` → gear with 40 teeth, 1.5mm module

    • This is not text-to-CAD AI yet — it's template expansion. Type a keyword, get a pre-coded OpenSCAD snippet. Phase 2 (Q2 2026) brings real LLM-driven geometry generation.


    Who This Is For


    Mechanical Engineers

    Generate parametric parts for assemblies. Export STL for rapid prototyping.


    Product Designers

    Iterate on enclosures, brackets, and fittings without firing up Fusion 360.


    Architects

    Prototype custom building components — facade panels, joinery details, parametric screens — then export to your main CAD tool.


    Students & Educators

    Learn parametric design with zero software costs. Browser-based means it runs on Chromebooks.


    Fabrication Shops

    Quick toolpath generation for simple parts. Export DXF for CNC.


    Phase 2: Text-to-CAD with AI (Q2 2026)


    Natural Language Input

    Instead of learning OpenSCAD syntax:

  • "flange 200mm diameter 8 holes M12" → generates bolt pattern
  • "parametric bookshelf 5 shelves adjustable" → generates shelf system
  • "structural bracket 50x50 L-shape 10mm thick" → generates bracket geometry

    • AI Model Integration

    Backend options under evaluation:

  • GPT-4 with CAD knowledge fine-tuning
  • Custom LLM trained on OpenSCAD corpus
  • Hybrid: LLM for intent parsing + rule engine for geometry

    • Why This Matters

    CAD has always been code-centric (OpenSCAD, Grasshopper, AutoLISP). AI lowers the barrier: describe what you need, get parametric code you can edit.


    Real-World Workflows


    Workflow 1: Custom Facade Panel


    Old Way:

    1. Open Rhino/Grasshopper

    2. Script parametric pattern

    3. Bake to mesh

    4. Export

    5. Import to fabrication tool

    **Time:** 2-3 hours for a novel pattern


    CAD AI Way:

    1. Type "hexagonal panel 500x500 parametric perforation pattern"

    2. Adjust parameters in OpenSCAD

    3. Export DXF

    **Time:** 15-30 minutes


    Workflow 2: Joinery Detail Prototyping


    Old Way:

    CAD joinery from scratch in Revit/ArchiCAD → slow iteration


    CAD AI Way:

    Generate mortise-tenon joints parametrically → test fit virtually → export for shop drawings


    Workflow 3: Student Assignment


    **Scenario:** Design a parametric staircase baluster

    **Without CAD AI:** Need Rhino license ($995) or Fusion 360 subscription

    **With CAD AI:** Free browser access → learn parametric thinking → export for presentation


    Technical Architecture (For The Curious)


    **Frontend:** React 18 + TypeScript + Vite

    **3D Rendering:** Three.js + React Three Fiber

    **CAD Engine:** OpenSCAD WASM (GPL v2) — compiles in-browser

    **State:** Zustand for app state

    **Deployment:** Vercel Edge, globally distributed


    Why OpenSCAD?

  • Parametric by default (everything is code)
  • Proven 15+ year track record
  • WASM port means no server-side rendering costs
  • GPL-compatible with commercial use via proper licensing

    • Why Browser-Based?

  • Zero installation friction
  • Works on any OS (Windows, Mac, Linux, even Chromebook)
  • Models compile on your machine (privacy + no server cost for compute)
  • Instant updates — no version hell

    • Pricing & Credits


    CAD AI uses the AICoin credit system shared across all AIConcept tools.


    Current (Phase 1):

  • Keyword generation: FREE (client-side compilation)
  • Exports: FREE
  • 3D preview: FREE

    • Phase 2 (AI-Powered):

  • Text-to-CAD via LLM: 5-15 AICoin per generation (estimate)
  • Complex assemblies: 20-40 AICoin
  • Free tier: 100 AICoin/month for testing

    • Why Credits vs Subscription?

  • Pay only for AI compute, not software access
  • Credits work across DocuMind, Archi, Video, 3D apps
  • No monthly lock-in
  • Transparent per-feature pricing

    • Comparison: CAD AI vs Traditional Tools


    | Feature | CAD AI | Fusion 360 | Rhino + Grasshopper | OnShape |

    |---------|--------|------------|---------------------|---------|

    | **Install** | None (browser) | Desktop app | Desktop app | None (browser) |

    | **Pricing** | Pay-per-use | $680/year | $995 + $395 | $1500/year |

    | **Parametric** | Yes (code-first) | Yes (timeline) | Yes (visual script) | Yes (FeatureScript) |

    | **AI Generation** | Q2 2026 | No | No | No |

    | **Collaboration** | Share URL | Cloud collab | Manual | Cloud collab |

    | **Learning Curve** | Low → Med | Medium | High | Medium |

    When to use CAD AI:

  • Quick parametric parts
  • Learning CAD without investment
  • Cross-platform workflows
  • AI-assisted design (Q2+)

    • When to use traditional CAD:

  • Complex assemblies (100+ parts)
  • BIM integration (Revit/ArchiCAD)
  • Advanced surfacing (Rhino SubD)
  • Team collaboration with version control (OnShape)

    • Limitations (Transparency Matters)


    What CAD AI Won't Replace (Yet):

  • Full BIM workflows (no Revit interop)
  • Architectural documentation sets
  • Complex surfacing (NURBS, SubD)
  • Large assemblies with constraints
  • Rendering (no materials/lighting yet)

    • What It's Good At:

  • Parametric mechanical parts
  • Custom fabrication geometry
  • Educational prototyping
  • Quick conceptual 3D
  • Export prep for other tools

    • Getting Started (5-Minute Walkthrough)


    **Step 1:** Visit [cad.aiconcept.art](https://cad.aiconcept.art)


    **Step 2:** Sign in (free AIConcept account)


    **Step 3:** Try keyword generation:

    Type: `cube 100 100 100`

    Click Generate → see 3D preview


    **Step 4:** Adjust OpenSCAD code (left panel):

    Change `100` to `50` → instant update


    **Step 5:** Export

    Click Export → choose STL → download


    **Step 6:** Explore templates

    Gear, bracket, enclosure templates → parametric starting points
