A file goes in. The cut length comes out.
Trace reads the geometry in your STEP file, separates the outer contour from the cutouts and the bevels, and gives you the length to cut. Part by part.
Pick a part: the geometry appears, the cut paths draw themselves in red, and the analysis unfolds beside it. Everything is pre-computed — the page asks nothing of anyone, and nothing leaves your browser.
So you measure contour by contour. You miss a hole, you round off a radius, you add a margin to be safe. The price rests on an estimate nobody could reproduce exactly — not even the person who made it.
Measuring by hand is cheap one part at a time. It is the total that costs, and it appears on no line of your accounts.
A ballpark figure. Run the numbers on your own volumes.
And time is only half of it. A measuring mistake is invisible: it goes into the price, and shows up on the invoice.
Trace opens the STEP exactly as your CAD exports it — no conversion, no tidying up first.
Flat plate, round tube, rectangular tube or complex profile: the part is identified before it is measured.
Every face is sorted, every edge tied to what it actually is — a cut, a bevel, an edge of stock.
Lengths add up by category, and kerf and lead-in come in as parameters you set.
