Cadrio3D

About

Cadrio3D — Professional 3D CAD for iPad & iPhone From sketch to solid, drafting, and mechanism simulation. Cadrio3D is powered by a true B-rep kernel (OCCT), delivering modeling precision you wouldn't expect from your fingers and Apple Pencil. 2D Sketching Points, lines, polylines, circles, arcs, rectangles, polygons, curves, and text Draw from intersections and tangents, or by X/Y/Z offset from a reference point 3D sketching directly in space, with axis and mesh-face snapping Rich snapping and tracking: endpoints, centers, intersections, quadrants, angles, and tracking-line crossings Editing & Transforms Trim, extend, offset, rotate, move, mirror, and scale Corner trim and fillet, linear/circular patterns, join, split, and group Long-press to move endpoints, drag to move shapes 3D Solid Modeling Extrude (new, join, or cut — including curved faces and offset faces) Revolve, sweep, screw threads, and bridging (loft) Fillet, chamfer, and shell (hollowing) Boolean operations (union, subtract, intersect) 3D patterns, edge/dimension-based scaling, and editable fillet radii Seal 3D sketches into solids, connect faces, and manage parts in a list Drafting & Measurement Paper-space drawing sheets with hidden-line removal and DXF export Dimension measurement, line styles, and construction lines Type formulas ( + − × ÷ ( ) ) directly into numeric fields Mechanism Simulation & AR Add linkage joints and bring your model to life with a physics engine Place solids in the real world with AR (collision checks on LiDAR devices) Scanning & AI Object and space scanning to capture real-world geometry (supported devices only) A built-in MCP server lets AI assistants on your local network drive Cadrio (client setup required) Import / Export Import: STEP, STL, DXF, JWW, and Cadrio (.cr3) Export: Cadrio (.cr3), STEP, DXF, and individual selected solids Save in-app, to your library, or to Files / iCloud; place reference images at true scale Cadrio Pro Model for free to try it out. Cadrio Pro (in-app purchase) unlocks unlimited saves, file export, and library export.
