How to prepare DXF Files?

Preparing your DXF file correctly is the key to accurate pricing and error-free manufacturing. Our automated system requires a few basic rules to be followed.

Core Principles:
  • Scale 1:1 – Dimensions in the file must match the desired size in millimeters.
  • Clean Geometry – Remove all construction lines, dimensions, frames, and text (unless intended for engraving).
  • Closed Contours – All shapes to be cut must form closed loops without self-intersections.
Engraving Marking:

We offer two marking methods: Vector (lines, outlines) and Raster (filled areas). Follow these steps for correct engraving detection in your DXF file:

  • Create a new layer in your CAD named ENGRAVE.
  • Place everything intended for engraving onto this layer.
  • Vector Engraving: Use standard entities (LINE, ARC, LWPOLYLINE).
  • Raster Engraving: Use the HATCH entity (fill) in the ENGRAVE layer.
  • Other entities in different layers will be interpreted as a standard cut (CUT).

Autodesk Fusion 360 is one of the most widely used tools for 2D and 3D design.

Exporting to DXF

  1. Create a sketch on your model's surface or select an existing one. Fusion 360 Create Sketch
  2. Right-click the sketch in the Browser on the left.
  3. Choose Save As DXF.
  4. When exporting from a 3D model (using Sheet Metal faces), we recommend using Create Flat Pattern and exporting the DXF from there. Fusion 360 Export DXF
Watch for Units: Fusion 360 always exports DXF in document units. Ensure you have millimeters set.

Inkscape is an excellent free vector editor for graphical designs.

Exporting to DXF

  1. Before exporting, convert all objects to paths (Path -> Object to Path).
  2. Go to File -> Save As...
  3. In the format list, select Desktop Cutting Plotter (AutoCAD DXF R14) (*.dxf). Inkscape Save as DXF
  4. In the export settings dialog, choose units mm and character encoding Latin 1. Inkscape DXF units settings
Tip: If the DXF appears empty or broken after import, check in Inkscape if your stroke width isn't excessively large.

General rules for other professional CAD systems:

  • DXF Version: We recommend AutoCAD R12 ASCII DXF (older but most stable version).
  • Units: Always millimeters (mm).
  • Geometry: Use only LINE, ARC, CIRCLE, and LWPOLYLINE. Avoid splines (unless the system can convert them).
  • Resolution: Set an adequate number of segments for circles (super-high resolution isn't needed, but a square instead of a circle is an error).
Tip: An excellent and simple tool for checking and cleaning DXF files is the free QCAD.
