How to Export Vector Files for Laser Cutting in CorelDRAW

Exporting vector files for laser cutting in CorelDRAW requires proper artwork preparation, correct stroke sizing, and selecting the right file format for your laser software. This guide covers how to set up cut and engrave lines, convert elements to vector paths, choose formats like DXF, SVG, or PDF, and configure export dialog settings to ensure your laser cutter processes the design with clean edges and accurate dimensions.

1. Prepare Artwork and Line Properties

Laser cutting software distinguishes between cutting and engraving based on stroke weight and color coding.

  • Set Line Thickness to Hairline: Select all paths intended for cutting and change their outline width to Hairline (or 0.001 inches / 0.076 mm). Laser drivers interpret thicker lines as raster engraving rather than vector cutting.
  • Assign Standard Colors: Use distinct RGB colors to separate operations. Common conventions include RGB Red (255, 0, 0) for cutting, RGB Blue (0, 0, 255) for vector scoring, and RGB Black (0, 0, 0) for raster engraving.
  • Remove Fills for Cut Paths: Ensure cut paths have no fill color applied, leaving only the outline visible.

2. Convert Objects and Text to Curves

Unconverted text and complex shapes can cause font substitution errors or broken paths in laser control software.

  1. Select your entire design by pressing Ctrl + A.
  2. Convert all text and native shapes to paths by pressing Ctrl + Q (or go to Object > Convert to Curves).
  3. If your design contains overlapping cut paths, combine them using the Weld tool (Object > Shaping > Weld) to eliminate duplicate cuts that could burn the material.

3. Select the Best Export Format

The optimal format depends on your laser software (e.g., LightBurn, RDWorks, or proprietary machine drivers):

  • DXF (AutoCAD): Ideal for CAD-based laser software like RDWorks and LaserCAD. Preserves true dimensions but does not always retain color mapping reliably.
  • SVG (Scalable Vector Graphics): Best for web-based lasers (e.g., Glowforge) and modern control programs like LightBurn. Preserves colors, layers, and vector curves accurately.
  • AI (Adobe Illustrator) or PDF: Highly compatible with LightBurn and universal print drivers (Epilog, Trotec). Retains layer organization and exact scaling.

4. Export the File

  1. Click File > Export (or press Ctrl + E).
  2. Choose your destination folder, name the file, and select your chosen format from the Save as type dropdown menu.
  3. Check the Selected only box if you only want to export specific elements on your artboard.
  4. Click Export to bring up the format-specific settings dialog.

5. Configure Format-Specific Export Settings

For DXF Export:

  • Set Export version to AutoCAD 2008 or AutoCAD R14 for maximum compatibility.
  • Under Export units, ensure the units match your CorelDRAW document units (Inches or Millimeters) to prevent scaling errors.
  • Set Export text as to Curves.

For SVG Export:

  • Set Styling to Presentation Attributes.
  • Under Units, select your document unit (e.g., Millimeters or Inches) to maintain a 1:1 scale.
  • Ensure Curves is selected for font handling.

For PDF Export:

  • Use the PDF/X-1a preset or set the compatibility to Acrobat 6.0 (PDF 1.5).
  • Under the Color tab, set color management to RGB (or match the native color mode of your laser software).
  • Under the Objects tab, ensure Export all text as curves is checked.

6. Verify the Output

Open your laser control software and import the newly exported file. Verify that the overall dimensions match your original CorelDRAW design, the lines are assigned to the correct cutting layers, and no unwanted duplicate paths exist before running the job.
