A Step-by-Step Guide to Preparing DXF Files for Waterjet Cutting

When it comes to waterjet cutting, one of the best ways to speed up your job and avoid costly mistakes is to send us a clean, ready-to-cut DXF file. Whether you’re an engineer, product designer, university student, or just someone familiar with CAD, this guide will walk you through exactly what we need — and what to avoid.

We’ve kept it simple and jargon-free. With the right file, we can often start cutting the same day, especially if you’re supplying the material too.

What Is a DXF File?

A DXF (Drawing Exchange Format) file is a 2D CAD file that tells our machine where to cut. Think of it as a digital blueprint — it contains all the geometry (lines, arcs, and curves) that our waterjet follows during cutting.

Most CAD programs can export to DXF, including:

• Autodesk AutoCAD
• SolidWorks
• Fusion 360
• Rhino
• DraftSight
• FreeCAD

Tip: Save in AutoCAD 2000 format for best compatibility.

What We Need in Your DXF File

1. Only Include the Cut Geometry

• No labels, title blocks, or construction lines.
• Just the shapes and holes you want us to cut — nothing else.

2. Use a 1:1 Scale (Millimetres Preferred)

• Ensure your design is full size — no scaling.
• Include one dimension for us to check the scale.
• Let us know what units you’re using (mm or inches).

3. Join All Lines and Curves

• Make sure all lines and arcs are connected to form closed shapes.
• Avoid broken polylines or overlapping segments — they can confuse the software.

4. No Duplicate or Layered Geometry

• Overlapping lines can cause double-cutting, leading to poor results.
• Clean, single-line paths are best.

5. Avoid Small Gaps and Fragile Features

• Keep at least 3–5mm between internal cuts and edges.
• Very small tabs or unsupported shapes may not survive the cutting process.

6. Nesting: Send Multiples as Individual Parts

• If you need more than one of the same part, supply each as a separate file.
• We can nest them more efficiently, saving you money on material.

Don’t Have a DXF File? We Can Help

If you’ve got:

• A sketch on paper
• A photo with rough dimensions
• Just a concept in your head

…we can help turn it into a DXF file. Send us what you have — we regularly draw parts for customers who don’t use CAD.

Why It Matters

A good DXF file means:

• Lower setup costs
• Faster turnaround
• Cleaner, more precise cuts
• Less back and forth during quoting

It also helps us nest your parts more efficiently, reducing material waste — especially important for large jobs or expensive materials. Why waterjet cutting is best for Hardox and Bisalloy

Final Tips Before You Send

When you email us your DXF, please include:

• Material type and thickness
• Quality of the cut required
• Quantity of parts
• Any urgent deadlines or timing requirements

If you’re sending multiple files, zip them into one folder for easier handling.
