Functional Gear Design, Made Intuitive

Everything you need to move from a blank canvas to production-ready geometry, directly in your browser.

Phase 1

Design

  • The Fundamentals: Define your gear geometry with total control over module, pressure angle, profile shift, and backlash.
  • Custom Layouts: Build complex geartrains and planetary systems using an intuitive X,Y coordinate grid and angular positioning.
  • Reverse Engineering: Input known measurements to solve for missing parameters and recreate obsolete parts with ease.

Phase 2

Validate

  • Visualize: Animation controls with interactive play, pause, and reverse to visualize mesh interference and verify rotation.
  • Gear Data Reports: Access gear data blocks including diameters, tooth thicknesses, tolerances, and inspection measurements.
  • Part Numbers: Assign part numbers and custom descriptions to every gear in your gearset to stay organized.

Phase 3

Execute

  • Save: Save geartrains online and reopen the same assembly from any device without rebuilding your layouts.
  • Shareable Links: Generate shareable links to send your gear data for collaboration or create an iframe to embed in your website.
  • CAD Export: Export optimized DXF and SVG files to import into your CAD software. Start building your parts today.
