How to Make CNC-Ready Vector Files
CNC machines need clean, closed vector geometry to generate accurate toolpaths. Learn how to convert any image or logo to a CNC-ready SVG or DXF file for use with Vectric VCarve, Fusion 360, Easel, and other CAM software.
About How to make CNC-ready vector files
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.
Step 1 — Start with the right source For logos and graphics: upload the PNG or JPG to the vectorizer and download the SVG. 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.
