How to Make CNC-Ready Vector Files
CNC machines need clean, closed vector geometry to generate accurate toolpaths. This protected workflow exports authorized SVG only; use a separate downstream tool for other file formats or machine instructions.

No account is required to create or view the protected preview. The preview accepts one PNG, JPEG, or WebP file up to 4 MiB; other source formats must be exported or converted to one of those formats first. Editable SVG export requires paid or complimentary access. Review the exported SVG in the appropriate downstream software; non-SVG formats and machine instructions require separate conversion.

CNC CAM software generates toolpaths from vector geometry. The cleaner and simpler the vector file, the more accurate the machined output. Creating CNC-ready vector files from scratch or from raster sources requires attention to path quality, closure, and simplification.
The protected preview is available without an account; editable SVG export requires paid or complimentary access. For technical drawings: export from CAD as DXF directly — no tracing needed.
Step 2 — Check and fix path closure Open the SVG in Inkscape. Run Path > Break Apart, then select each path and check for open nodes in the XML editor or Node editor. Open paths produce incomplete toolpaths in CAM software. Close all paths manually or use Path > Close Path.
Step 3 — Simplify paths Run Path > Simplify repeatedly until the design is at its simplest form without losing recognizable shape. A good CNC vectorized logo has hundreds of nodes, not thousands. Overly complex paths cause slow machining and rough surface finish.
Step 4 — Scale to real-world dimensions Set the document units to mm or inches in Inkscape. Scale the artwork to the intended machined size. CAM software imports vectors at document scale — incorrect scaling requires re-scaling in the CAM tool.
Step 5 — Export for CNC For most CAM software: DXF (File > Save As > DXF in Inkscape). For Easel: SVG import works directly. For Fusion 360: DXF import or the Add-ins > Shaper Origin workflow.
