OpenDesign is a complete creative studio on your iPhone and iPad. Instead of juggling separate apps for modeling, drawing, electronics, architecture, media, and learning — you get one workspace built for makers, students, hobbyists, and professionals who want to go from idea to finished project fast. • 3D Design — Model, sculpt, extrude, and refine real geometry with intuitive touch controls and precision tools • 3D Printing & Animation — Prepare models for printing, slice for G-code, rig motion, and bring designs to life • House Plans — Draw floor plans, explore layouts in 3D, and validate designs with built-in architecture tools • Circuit Design — Schematic capture, PCB layout, design rule checks, and fabrication exports • Sketch & Painting — Draw with Apple Pencil on iPad, paint concepts, and turn art into playable arcade games • Motion & Materials — Explore mechanical motion, material behavior, and engineering concepts hands-on • Chemistry — Build molecules, run simulations, and learn STEM concepts visually • Audio Studio — Record, edit, and mix audio in a mobile production workspace • Video Studio — Edit on a timeline, add effects, and share finished clips • Avatar Creation — Build 2D and 3D avatars with live face tracking and animation presets • 2D Arcade Games — Design and play games from your own sketches and sprites CAPTURE THE REAL WORLD Use LiDAR scanning and photogrammetry on supported devices to capture rooms, objects, and environments — then edit, repair, and reuse them inside your projects. Turn scans into meshes, animations, architecture references, or game assets. DESIGN YOUR WAY OpenDesign adapts to how you work. Orbit and zoom through 3D scenes with natural gestures. On iPad, Apple Pencil support gives you tighter control for sketching and precise selection. Switch between project types without losing your library — everything stays organized in one place with folders, search, and sorting. FROM PROTOTYPE TO OUTPUT Export your work in the formats you need — including STL, OBJ, USDZ, GLTF, DAE, STEP, Gerber, PDF, and more with OpenDesign Pro. Share models for AR Quick Look, send files to a 3D printer, export PCB fabrication data, or hand off assets to game engines and other tools. BUILT FOR LEARNING AND BUILDING Teaching tools, calculators, tutorials, and guided workflows are woven throughout — so OpenDesign works whether you are learning fundamentals or shipping a real project. Explore circuits, test mechanical ideas, study chemistry, animate characters, or prototype a product in a single app. OPEN DESIGN PRO Upgrade to unlock unlimited projects, advanced 3D and printing tools, full export access, and premium workspaces including Video Studio, Circuit Design, and Architecture. Subscriptions are managed through your Apple ID and can be canceled anytime. OpenDesign brings modeling, making, media, and STEM together in one open creative environment.
