SimplerCAD vs FoldForm

Turn your ideas into 3D designs with SimplerCAD. Build models from basic shapes, adjust dimensions, and combine objects in a hands-on CAD workspace. CREATE AND EDIT Add shapes, move, rotate and scale objects, and use grid and snap controls for precise placement. Switch between different model views as you work. SAVE AND SHARE Save editable projects locally, open them again to keep working, and export models in formats including STL, OBJ and GLB. Use your device's sharing options to send files to the destination you choose. LEARN AS YOU GO Explore the built-in Help center for guides to the workspace and modeling tools. Designed for makers, hobbyists and anyone learning 3D modeling. Designed for iPhone. This version saves projects locally and does not require an account. Contains banner advertising.

FoldForm is precise 3D CAD for makers and 3D printing, made for touch. Push and pull faces with a finger or Apple Pencil, sketch a profile and extrude it, and type exact sizes as you go. Every step stays editable. MODEL • Tap a flat face to see the part's size, then drag the arrow or type a new size; +5 or -5 changes it by that much. • Round and chamfer edges, shell a body to a wall thickness, offset faces. • Tap a hole's wall and type a new diameter. Delete a hole, fillet or chamfer and the faces around it close the gap. • Extrude sketch profiles (a distance, both ways or up to a face; as a new body, joined, or cut, also through everything), revolve them, or loft between shapes on different planes. • Sizes accept units and arithmetic: 25, 1in, 2.5cm, 20+5, (10+2)*3. SKETCH • Sketch on the ground, an origin plane, a construction plane or any flat face. • Line, rectangle, center rectangle, polygon, circle, arc, tangent arc and slot; trim, round a corner, offset, mirror and pattern. • Constraints (horizontal, vertical, parallel, perpendicular, equal, tangent, concentric, midpoint, symmetric, distances, angles) shown as small glyphs, and a "Fully defined" status. • Drag a line, circle or point to change a sketch; tap a size to type it. On a face, points snap to its corners, edge middles, center and holes, with a magnifier under your finger. BODIES • Move, rotate and align bodies, lay a face on the build plate, mirror and pattern (in a row or around an axis), union, subtract and intersect. • Construction axes and planes to rotate about, pattern around, mirror across, align onto or sketch on. • The Model panel lists every sketch, body and step: change a value later, suppress or delete a step. Everything can be undone. MADE FOR 3D PRINTING • A Hole tool with ISO clearance and tap sizes, counterbores and countersinks from M2 to M6, with a print allowance (0.2 mm to start with) so screws fit, plus heat-set insert holes. • Raised or engraved text on a face, for labels and version marks. • Measure a face's size, the distance or gap between two faces or edges, and angles. • Export STL or 3MF (millimeters; 3MF keeps each body a separate object) for your slicer, or STEP for other CAD programs. Import STEP files. YOUR FILES • Projects keep the full history, so sketches and steps stay editable after reopening. • Export opens the share sheet: send the file straight to your slicer app, AirDrop or Mail. Share a whole project the same way. • Projects are saved in FoldForm's folder in the Files app, exports in its Exports folder. Open projects and STEP files from the Files app or Mail. • A Home screen with your projects and their previews. • Unsaved work is kept safe in the background and offered again if the app closes. • When a step cannot be done, FoldForm says why in plain words, often with a size that works, and your model stays as it was. ON IPHONE AND IPAD • One app for iPhone and iPad. On iPhone the tools sit along the bottom and the value box docks where it covers nothing you selected; on iPad the full layout, also in Split View and Stage Manager. • One finger orbits, two fingers pan and zoom, a two-finger tap undoes and a three-finger tap redoes. A view cube shows how the view is turned; tap it to look from a side. • Apple Pencil on iPad and iPhone Duo: pen mode lets the Pencil draw and select while your fingers only move the view. • On iPhone Duo: closed, the phone layout; opened, the full layout on the inner display, with a larger canvas for your model. FREE TO START Every tool is free for one project at a time. A one-time in-app purchase unlocks unlimited projects on your iPhone and iPad.
