Want to check a sliced 3D print before you send it to the printer? Pathly opens a G-code file on your iPhone and shows the toolpath in 3D, layer by layer, with print time, filament and size at a glance.
Tap Open a G-code File and pick a .gcode, .gco or .nc file from Files, or open one straight from another app. Pathly reads it on your iPhone and draws the path.
• 3D TOOLPATH — extrusion moves in color, travel moves in grey, over a soft ground plane. Pinch to zoom and drag to rotate.
• LAYER SCRUBBER — slide through the print to see it build up layer by layer, with the current layer number and Z height.
• PRINT STATS — estimated print time, filament used, model size (X × Y × Z), layer count, extrude and travel moves, total path length and maximum feed rate.
• READS REAL SLICER OUTPUT — G0/G1 moves and G2/G3 arcs, absolute or relative positioning and extrusion, millimeter or inch units, and files up to 80 MB.
• SHARE / EXPORT — send the G-code file on to another app, AirDrop or Files.
Honest scope: Pathly is a viewer — it doesn't slice, edit or send jobs to a printer. The time estimate uses path lengths and feed rates without acceleration, so your slicer's estimate may differ; filament volume assumes 1.75 mm filament. Binary G-code (.bgcode) isn't supported, and CNC or laser files without extrusion show every move as travel. Very dense files are thinned for display; the stats still count every move.
Your files are opened on your iPhone only — nothing is uploaded and no account is needed.
Viewing is free and unlimited. The free version shares or exports 3 files; a one-time $4.99 purchase unlocks unlimited exports. No subscription, no ads.
