What Files Do You Need for CNC Cutting?

Short answer: for CNC cutting, a vector file is best: a DXF or an SVG drawn at full size, with every cut line closed. If you don't have one, a dimensioned drawing, a PDF or even a sketch with measurements is enough for us to quote. We can draw the file from there.

The best files for CNC cutting

• DXF. The standard for parts. Most CAD programs (AutoCAD, Fusion, SolidWorks, Onshape) export it.
• SVG. Common for signs, logos and artwork. Illustrator, Inkscape and most design programs export it.
• PDF or AI with vector lines. Works if the drawing is made of lines, not a flattened picture.

A JPG or PNG is a picture made of pixels, not cut lines. We can still work from one, but it has to be traced into a vector file first.

How to set up your file

1. Draw it at 1:1 scale. Note whether you used inches or millimeters.
2. Close every shape. Open gaps in a line can't be cut cleanly.
3. Remove duplicate and overlapping lines. Overlaps make the machine cut the same path twice.
4. Convert text to outlines so the font doesn't change when we open the file.
5. Mark what gets cut, carved or engraved. Separate layers or colors work well.

What to send with your file

• The material and thickness (for example, 3/4" birch plywood, 1/4" acrylic or 1/2" HDPE)
• How many pieces you need
• Any tolerances or dimensions that matter most
• Finish details, such as edge profiles, sanding or painting
• When you need the parts

Don't have a file?

Send a drawing with dimensions, a photo of an existing part next to a ruler, or a sketch. We will tell you what we need to quote it. If your parts are under NDA, send the NDA with your drawings and we will sign it before we quote.

How big can the part be?

Our ShopSabre IS510 CNC router has a 5×10' working area. It takes a full 4×8 sheet in one setup and cuts wood, plywood, plastics, composites, foam and aluminum. See our CNC manufacturing page for the full list of materials.
