Description
Open STEP, IGES, STL, OBJ and DXF files on your phone — then actually change them.
Digit 3D is a complete parametric CAD workspace with a real solid modelling kernel, running entirely on your device. No account, no cloud, no ads.
VIEW AND INSPECT • Open STEP / STP, IGES / IGS, STL, OBJ and DXF • Rotate, zoom, isolate and hide parts; set per-face colours • Cut along any plane with a draggable section gizmo • Measure distance, angle, radius, area and local curvature • Body properties: volume, bounding size, surface area, plus weight and cost from 20 built-in materials • Draft angle and wall thickness analysis with colour banding
3D MODELING • Parametric sketches with geometric and dimensional constraints • Extrude, revolve, sweep, loft through curves and surface fill • Boolean union, subtract and intersect across multiple bodies • Fillet, chamfer, shell, draft and curvature-continuous blends • Linear, circular and mirror patterns; move, copy and rotate bodies • Synchronous editing — push, pull and offset faces on imported geometry • Datum planes, sketch on any face, and raster image underlays for tracing • Full feature tree with rollback, edit and multi-step undo
2D DRAWINGS FROM YOUR MODEL • Three-view and isometric layouts generated from the 3D model • Section views, detail views and centrelines • Automatic dimensioning, manual dimensions and tolerances • Text notes and leaders • Standard title block and multi-page sheets • Export to DXF or PDF
2D DRAFTING • Lines, polylines, rectangles, circles, arcs and precise geometry • Aligned, linear, radius, diameter and angle dimensions • Object snaps, layers, layer visibility and measuring tools • Export as DXF or PNG
BUILT FOR REAL INPUT • Full mouse support with the button mapping professional CAD users expect • Configurable keyboard shortcuts across model and sketch modes • Radial command menu for fast tool access • Phone and tablet, portrait or landscape • Guided interface tour, step-by-step tutorials, and long-press help on any tool
FILE EXCHANGE • Import STEP, IGES, STL, OBJ and DXF • Append imported geometry into an existing model • Export STEP for CAD exchange and STL for 3D printing • Export drawings as DXF and PDF • Editable projects are saved locally in the MCAD format with full history
