Free tool · NC1 / DSTV viewer
See the part inside an NC1 file
Drop in a .nc1 file and see it drawn — outline, cutouts, holes, scribed marks — with the header decoded into a plain table. New to the format? Read the guide →
Read this firstRuns entirely in your browser. Your file is never uploaded — there is no server to upload to.
This page is plain client-side code: no analytics, no requests carrying your data. The only external request it makes is loading its font.
Drop NC1 files anywhere in this box — or pick them, or try the built-in sample. Multiple files are fine; they queue up in a list.
Limits, stated plainly: this viewer draws plate-style parts — ST header, AK outlines and IK cutouts (corner-radius values are read but corners are drawn as straight segments), BO holes and slots, SI marks as crosses with text. PU/KO marking geometry and unknown blocks are counted, not drawn. Parts with multiple faces (beams: o/u/h) draw overlaid flat, not folded. Header decoding follows the standard field order; detailer dialects may shift fields. View-only — no editing, no export.
