How to Import .DXF, .SVG & .PDF Files at Exact 1:1 Scale in LightBurn, Illustrator & AutoCAD
Parametric Formulas & Dimensional Allowances
Occurs only when an SVG file uses unitless pixel attributes instead of explicit physical 'mm' or 'in' width/height attributes.
Exact ISO/PostScript conversion factor used in CadFold's native vector PDF engine.

| CAD / CAM Software | Recommended Format | Required Import Setting | How to Verify 1:1 Scale Before Cutting |
|---|---|---|---|
| LightBurn (CO2 / Diode / Fiber Laser) | .DXF or .SVG | Edit → Settings → File Settings → DXF Import Units: Millimeters (SVG auto-reads mm) | Select the DIMENSIONS scale bar and confirm Width = 50.00 mm |
| Adobe Illustrator | .SVG or .PDF | Open directly (do not 'Place' with Scale to Artboard); units read physical mm | Check Transform panel on the 50.0 mm calibration bar |
| AutoCAD / DraftSight / SolidWorks | .DXF (R2000) | Automatic ($INSUNITS = 4 Metric Millimeters embedded in header) | Use DIST command across the 50.0 mm scale bar |
| CorelDRAW | .PDF or .SVG | Import at 1:1 Original Size; set document units to Millimeters | Verify total blank width against the embedded title block |
| Cricut Design Space / Silhouette Studio | .SVG | Set SVG Import to 'Actual Size (mm)' in Preferences | Confirm bounding box dimensions match the embedded spec text |
| Fusion 360 / VCarve Pro / Carbide Create | .DXF or .SVG | Insert DXF → Units: Millimeter → Onesketch per layer | Verify outer cut contour against blankWidthMm × blankHeightMm |

Shop-Floor Troubleshooting & Engineering FAQs
Why does every CadFold file include a 50.0 mm and 1.00 inch scale bar at the bottom?
The embedded scale bar on the DIMENSIONS layer gives you a 2-second visual and mathematical sanity check inside your laser, CNC, or printing software. If the 50.0 mm bar measures exactly 50.00 mm in your software, your entire project is guaranteed to cut at 100% true 1:1 scale.
Should I delete or turn off the DIMENSIONS layer before sending the job to my laser cutter?
Yes! You can either uncheck 'Include 1:1 Spec Block & Scale Bar' inside the CadFold Studio before downloading, or simply set the gray DIMENSIONS layer to 'Output: OFF' inside LightBurn or AutoCAD.
What should I do if I have a third-party SVG or DXF file with broken scale or open paths?
Use our free Client-Side DXF/SVG Preflight Inspector & Laser Calculator (/tools/dxf-svg-preflight-and-laser-calculator/) to audit open contours, duplicate lines, bounding box dimensions, and machine cut time.
