DXF Export
How and when to export pattern pieces as DXF for pattern cutters and CAM/plotter systems, versus SVG for lighter-weight sharing.

What DXF carries
DXF (Drawing Exchange Format) is the CAD file format that pattern rooms, cutting tables, and automated cutters read. A DXF export from Niche Studio includes each pattern piece's cut line, internal lines (darts, pockets, placement marks), notches, grainline, and piece labels as vector geometry with real-world units.
When to export DXF versus SVG
| Use case | Recommended format |
|---|---|
| Sending pieces to a factory pattern room or CAM/cutter | DXF |
| Sharing a piece for visual review or a browser mockup | SVG |
| Archiving alongside a tech pack for reference | Either — DXF if downstream editing is expected |
| Importing into another CAD pattern system | DXF |
DXF preserves scale and layer structure (cut line vs internal line vs notch) that cutting software expects. SVG is lighter and renders reliably in any browser but does not carry the same layer conventions pattern software relies on.
Before you export
- Seam allowance is added and visible as a separate line from the stitch line.
- Grainlines are set on every piece.
- Notches are placed at every match point.
- Piece names and quantities are labeled so a cutter's table matches your BOM.
