OrbitCAD

OrbitCAD turns plain-English descriptions into real, engineering-grade mechanical parts — no CAD training required. Just describe what you need: "spur gear, module 2, 24 teeth" or "arm joint, 40mm bore" — and OrbitCAD generates accurate, parametric 3D geometry in seconds. Rotate, inspect, and export it as STEP or STL for 3D printing or professional CAD workflows. WHAT YOU CAN DESIGN - Gears — spur, helical, bevel, worm - Planetary gearboxes - Shafts, couplings, and drive components - Robotics parts — arm joints, mounts, and more - Drone propellers and custom blade geometry - And an expanding library of mechanical components BUILT FOR REAL ENGINEERING Every part is generated with accurate dimensions, correct tooth profiles, and proper mechanical relationships — not approximations. Inspect wall thickness, diameters, and tolerances directly in the app before you export. EXPORT READY Download STEP files for professional CAD software, or STL for 3D printing — straight from your phone. Whether you're prototyping a robotics project, need a quick replacement part, or just want to explore mechanical design without opening a full CAD suite, OrbitCAD gets you from idea to exportable geometry in one conversation.
