About this app
3D Modeling is a full modelling studio that runs entirely on your phone or tablet. No cloud, no account, no upload — your projects are files on your own device.
FREE AND PRO
Free covers three projects, OBJ and STL export, rendering up to 1080p, video up to 720p and ten saved library objects. Pro (a monthly or yearly subscription, or a one-time lifetime purchase) removes those limits and adds 4K and 8K rendering, USDZ, glTF, PLY, FBX, DAE, 3MF and Alembic export, drawing PDF and DXF export, STEP AP242 with PMI, version sync over WebDAV, scan retopology and sharper scan textures.
MODEL
Start from 14 primitives or an imported file, then work the mesh directly with your finger: extrude, inset, bevel, chamfer, loop select, bridge, knife and boolean union / difference / intersection. Seventeen non-destructive modifiers stack in any order — subdivision, mirror, array, solidify, bend, twist, taper, wave, noise, displace, smooth, weld, decimate, lattice, shrinkwrap, screw and skin. A SketchUp-style line and push/pull tool with inference snapping is there when you would rather draw than edit vertices.
SCULPT
Seventeen brushes with dynamic topology, symmetry and multiresolution levels: draw, inflate, flatten, smooth, grab, pinch, snake hook, crease, scrape, elastic, twist, simplify, polish, trim, pose, rotate and mask.
PARAMETRIC CAD
A real feature history, in millimetres: constrained sketches, then extrude, revolve, sweep, loft, hole, thread, shell, draft, fillet, chamfer, rib, thicken, pattern, mirror and split. Change a named parameter and everything downstream regenerates. Thirteen worked templates (enclosure, bracket, gear, screw, bolt, nut, flange and more) to start from or take apart. Assemblies solve mates and joints between parts; motion studies, sheet metal, weldments, design tables and a hole wizard with standard fasteners are included.
EXACT GEOMETRY
Turn on exact geometry and a body is held as a true B-rep: a hole is a cylinder of radius 5, not a 40-sided pit. STEP export writes real solids any CAD package reads back.
ENGINEER AND DOCUMENT
Linear static, frequency, buckling, thermal and laminar flow studies with colour maps; a design checker for printing, machining, moulding and sheet metal; 2D drawings with hidden-line removal, sections, dimensions, GD&T and a title block.
REVERSE ENGINEERING FROM SCAN FILES
Bring in a mesh or point cloud your scanner exported and work back to CAD: clean and repair it, fit planes, cylinders, cones, spheres and tori, extract holes, fillets and patterns, snap them to sensible round numbers, and generate an editable feature history. Cross-sections, surface fitting, inspection reports and deviation maps are included.
3D PRINTING
A built-in slicer with eight infill patterns, supports, rafts and brims, thirteen quality presets and fourteen materials, writing G-code for Marlin, Klipper, RepRap and Bambu machines. Check printability first, then send the job straight to OctoPrint, Moonraker, PrusaLink, Duet or a Bambu printer on your Wi-Fi network and watch it from the app.
RENDER AND ANIMATE
Keyframe transforms, materials and morph weights on a timeline with a graph editor. Physics bakes rigid bodies, cloth, soft bodies and particles into keyframes. Render with the built-in rasteriser or the CPU path tracer, with ambient occlusion, bloom, depth of field and lighting from your own HDRI, and export MP4 video.
OPENS AND SAVES
Imports OBJ, STL, PLY, FBX, STEP, IGES, 3DS, DAE, 3MF, Alembic, DWG, glTF/GLB, USD/USDA/USDC/USDZ, and E57, LAS, XYZ, PTS and ASC point clouds. Exports OBJ, STL, PLY, glTF, FBX, DAE, 3MF, Alembic, USDZ, STEP, IGES, DXF and PDF.
A note on scanning: 3D Modeling works with scans that are already exported — it does not capture them with the camera. Bring in PLY, E57, LAS, OBJ, glTF or USDZ from a Revopoint, Creality, Einstar, Artec, Polycam or photogrammetry export and the whole cleanup, measurement, retopology and scan-to-CAD workflow is open to it.
