AI-Native CAD Engine

Built for AI integration, FEM simulation, and manufacturing-grade exports. From browser to production floor.

Industry First

The First CAD Engine Built for the AI → Simulation → Manufacturing Loop

Traditional CAD engines weren't designed for AI or simulation. confBuild was built from the ground up for the closed loop: AI generates geometry, FEM validates it, manufacturing constraints enforce producibility — all in one engine, running in the browser.

✓ AI-native architecture
✓ Built-in FEM simulation
✓ Manufacturing-grade exports
Performance

Optimized for Speed

Our CAD engine is built from the ground up for maximum performance. Using advanced techniques like WebGL acceleration, efficient memory management, and smart geometry caching, complex models render instantly in your browser.

  • WebGL-accelerated rendering with THREE.js
  • Efficient Boolean operations with BVH-CSG
  • Smart geometry caching and reuse
  • Optimized memory management
  • 60+ FPS even with complex models

Built for AI Applications

The CAD engine is designed with AI integration at its core. A clean, structured API enables AI systems to generate, modify, and analyze 3D models programmatically. Perfect for automated design generation and intelligent optimization.

  • Structured spreadsheet-based data model
  • Predictable, deterministic outputs
  • Clean API for programmatic access
  • Natural language to 3D model pipeline
  • AI-friendly parameter system

Simplicity

Easy to Use

Despite its power, the CAD engine is remarkably simple to work with. The spreadsheet-based approach means anyone familiar with Excel can create sophisticated 3D models without learning complex CAD software.

  • Familiar Excel-like interface
  • No programming required
  • Intuitive parameter controls
  • Real-time visual feedback
  • Comprehensive documentation

Technical Highlights

The engine behind AI → CAD → Production

Parametric Modeling

Create models with dynamic parameters that update in real-time.

Boolean Operations

Union, subtract, and intersect geometries with optimized BVH-CSG.

30+ Primitives

Cubes, cylinders, tubes, extrusions, I-beams, and many more shapes.

Multi-Format Export

Export to STL, OBJ, GLTF, STEP, DXF, and more formats.

Browser-Based

No installation required. Works in any modern web browser.

Scripting API

VBA-like scripting for advanced automation and custom logic.

Production-Ready Exports

From browser to manufacturing floor — every export format your production pipeline needs

STEP Export

STEP / IGES Export for CAD & Manufacturing

Export your parametric models as STEP (ISO 10303) files - the universal exchange format for professional CAD software. STEP files preserve precise geometry, making them ready for CNC machining, injection molding, and further engineering in tools like SolidWorks, Fusion 360, or FreeCAD.

  • ISO 10303 compliant STEP AP214 output
  • Preserves exact geometry and topology (B-Rep)
  • Compatible with all major CAD systems
  • Ready for CNC, laser cutting, and injection molding workflows
  • Individual parts or full assembly export

BIM Export

IFC Export for Building Information Modeling

Generate IFC (Industry Foundation Classes) files directly from your configurator. Architects and construction professionals can import confBuild models into Revit, ArchiCAD, or any IFC-compatible BIM platform. Ideal for parametric building components, facades, structural elements, and MEP parts.

  • IFC 2x3 / IFC 4 compatible output
  • Embed material and property data
  • Works with Revit, ArchiCAD, Tekla, and more
  • Parametric building components ready for BIM workflows
  • Supports structural, architectural, and MEP elements

Complete Export Pipeline

Beyond STEP and IFC, confBuild supports a full range of 3D export formats. Whether you need mesh files for 3D printing, optimized assets for the web, or engineering drawings, the right format is always available.

  • STL & OBJ for 3D printing and prototyping
  • glTF / GLB for web and real-time applications
  • DXF for 2D technical drawings and laser cutting
  • 3MF for advanced 3D print data (colors, materials)
  • PDF for documentation and client presentations
