Digit 3D is parametric 3D CAD for iPhone and iPad: sketch, model, assemble and make drawings. Sketch • Lines, circles, arcs, splines, ellipses, polygons and slots, with dimensions and constraints • Mirror; linear, circular and along-curve patterns; trim, extend, chamfer and fillet • Apple Pencil support for precise drawing Model • Extrude, revolve, sweep, loft, shell, fillet, chamfer, hole, thread, pattern and mirror • Auto boolean: cuts when it overlaps, joins when it touches, new body when apart • Direct editing: move, rotate and copy faces, with adjacent fillets following along • Surfaces, 3D curves and 3D splines • Parametric history: edit any step at any time, and replay how the model was built Assembly and drawings • Assembly lives in the modeling workspace: new parts, move parts, auto-detected mates, clash check • 2D drawings with standard views, sections and dimensions; 3D annotations export with STEP Two interfaces • Full: every command, with customizable side rails • Simple: tap a face and drag the arrow, easy for beginners Files • Import STEP, IGES, STL, OBJ, 3MF, 3DM, Parasolid (X_T) and DXF drawings • Projects are saved as encrypted .d3d files Privacy Policy: https://digit3d.top/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
