openshape3d is a direct-modeling CAD app built for touch. Sketch a profile, pull it into a solid, and keep cutting, blending and patterning until the part is done — no desktop, no subscription server, no file conversion dance. Geometry is computed by OpenCASCADE, the same open-source B-rep kernel used in professional CAD. Extrudes, primitives and booleans produce exact analytic surfaces, so a cylinder stays a true cylinder instead of a faceted approximation. SKETCHING • Sketch on a world plane, on any flat body face, or on an offset construction plane pulled off a face • Line, rectangle, circle, arc, ellipse, polygon and text-as-outline tools • Endpoint, midpoint, centre, vertex and grid snapping — draw with Apple Pencil • Trim, move/rotate gizmo, construction geometry, and reusable symbols • A full 2D constraint solver: coincident, parallel, perpendicular, tangent, equal, concentric, symmetric and more • Driving dimensions with inline arithmetic (type 25.4/2) pull geometry to value • The sketch tells you where it stands — fully defined, or how many degrees of freedom remain SOLIDS • Extrude a profile, or push and pull a face directly with automatic booleans: pull to add material, push to cut • Revolve, sweep along a chained path, loft through sections, and helix • Fillet and chamfer edges with live preview and drag-to-size • Shell a body hollow, with optional open faces • Union, subtract and intersect between bodies, computed off the main thread • Split a body with a plane or a sketch profile • Linear and circular patterns with ghost previews • Move, scale, rotate, mirror, translate point-to-point and align VIEWING • Orientation cube, six standard views, isometric and orthographic toggle • One finger orbits, two pan, pinch zooms — the camera never locks up • Section view that clips live against a plane, with a drag arrow and flip • Shaded, shaded without edges, wireframe with proper hidden-line removal, and X-ray • Marquee select with window/crossing semantics, and Select Through to reach a body buried behind others • Isolate to hide everything but the selection MATERIALS AND REFERENCE • Material presets — steel, aluminium, brass, plastics, rubber, wood — plus custom colour with metallic and roughness • Drop PNG or JPEG reference images onto any plane and trace over them MEASURE • Face area, body volume and bounding box on selection • Two-point distance with X, Y and Z deltas over snap points IMPORT AND EXPORT • Import STL and DXF • Export STL, OBJ, 3MF, GLB, USDZ and sketch DXF • Preview your model in AR with Quick Look

You watch a 3D printing video, you want the file, and there's no link anywhere. Share the post to PrintFinder and we find the actual model by reading the caption and the video frames, then searching MakerWorld, Printables, and Cults3D for a match. A notification arrives when it's found. HOW IT WORKS • Tap Share in TikTok or Instagram, then choose PrintFinder • We analyze the caption and the video frames to identify the object • We search the public model repositories for a match • You get a link to the original file, with a confidence rating The search runs on our servers, so you can close the app straight away. BUILD YOUR PRINT LIBRARY • Save any find, and sort your prints into collections • Browse what's trending across the repositories • Get recommendations based on what you've saved • Set your printer for tailored compatibility hints • Compare notes with other makers in the comments • Share a find with a friend in a tap CREATORS COME FIRST PrintFinder never hosts, copies, or re-uploads model files. Every result links to the creator's own page, under their own license. FREE AND PLUS Browsing, searching, and saving are always unlimited. Free includes 5 imports every month, and PrintFinder Plus raises that to 100. Invite friends and earn up to 15 bonus imports a month, every friend who joins with your code counts. Plus is a subscription billed through your App Store account. It auto-renews until canceled; manage or cancel anytime in Settings.
