🎯 What this tool does
You upload a DXF drawing of the part you want laser-cut. The tool reads the drawing, measures the total cut length and counts the number of pierces (start holes), then estimates how long the cut takes and what it should cost — including machine time, gas/consumables, material, setup, and your profit margin. It works entirely in your browser; nothing is uploaded to a server.
Cut length, pierces, part size.
Cut time + pierce time per your rates.
Cutting + material + margin.
🚀 Quick start (5 steps)
- 1
Upload a DXF. Drag your
.dxffile onto the upload box, or click to browse. - 2
Confirm the units. A popup asks whether the drawing is in millimeters, inches, etc. Pick the right one (see below).
- 3
Pick material & thickness. Choose the sheet material and thickness, and enter how many pieces you need.
- 4
Read the price. The cost breakdown updates instantly — cut length, time, weight, and a full price with margin.
- 5
Tune your rates once. Open ⚙️ Settings and set your machine rate, material prices, and cut speeds. They're saved in your browser for next time.
📏 Choosing the right units
DXF files don't always store their units reliably, so the tool asks you every time you upload. This matters a lot: the units decide the part's real size, which drives cut length, weight, and cost.
🔍 Reading the results
Note: Net weight uses the part's bounding rectangle, not the exact nested shape — it estimates the stock the part occupies, which is the usual basis for quoting.
💰 How the cost is built
The total is split into two clear parts so you (and your customer) can see exactly where the money goes.
✂️ Cutting Cost
- Machine time × machine hourly rate
- Gas / consumables per running minute
- Setup fee (one-time per job)
- Margin added on top
🧱 Material Cost
- Net weight × price per kg
- Scrap allowance (extra % for offcuts)
- Margin added on top
The grand total = Cutting Cost + Material Cost (× the quantity of parts).
⚙️ Settings & rates (do this once)
Click ⚙️ Settings in the tool. Everything is saved in your browser, so you only set it up once. The defaults are just starting points — calibrate them to your own machine and prices.
🧾 When the customer brings their own material
Tick “Customer provides own material” in Job Parameters. The material cost is then excluded from the total (it stays visible, struck through, for reference) and you only charge for cutting. Untick it to include material again.
🧮 The formulas (for the curious)
🛠️ Troubleshooting
Material cost shows 0
The selected material has no price per kg. Open Settings → Materials and enter a price, then Save. (Built-in materials auto-fill a default price.)
The part size / cost looks 25× too big or too small
Wrong units. Change the DXF Units dropdown (inches are 25.4× millimeters). The numbers recalculate immediately.
“No cuttable geometry found”
The DXF has no readable shapes in its ENTITIES section. Export again as a flat 2D DXF with real lines/arcs/polylines (not blocks or 3D solids).
Net weight is 0
The drawing's bounding box has no area — usually an open or incomplete outline. Check the part actually has a closed shape.

❓ FAQ
Is my file uploaded anywhere?
No. Everything runs locally in your browser. The DXF never leaves your computer.
How accurate is the estimate?
As accurate as your rate table. The geometry (cut length, pierces) is measured precisely; the time and cost depend on the speeds and prices you enter in Settings.
Which DXF entities are supported?
Lines, circles, arcs, ellipses, polylines (including curved “bulge” segments) and splines.
Does it account for nesting / sheet usage?
Material is estimated from the part's bounding rectangle plus a scrap %. It does not nest multiple parts onto a sheet.
Can I quote many pieces at once?
Yes — set the Quantity. Cutting and material scale with quantity; the setup fee/time is charged once.
