Use your actual inputs
Material densities and operating factors are editable planning assumptions. Replace them with supplier data or measurements for the configuration you intend to use.
Multiple DXF Nesting Tool
Upload several 2D DXF parts, set quantities and preview a sheet layout, utilisation and material balance in your browser.
PRIVATE BROWSER PROCESSING
One sheet plan. Multiple parts.
DXF files stay in your browser. One file represents one part; all files in a run share the same material and thickness. Add quantities and generate a bounded outline-based planning layout.
No parts added. Upload ASCII 2D DXF files or load the sample.
Ready. Maximum 20 files, 500 requested pieces; large searches have a time limit.
Non-part balance includes skeleton, holes, spacing and potential offcuts; it is not all reusable remnant. Actual-weight allocation, when entered, is proportional to net part area.
How this calculator works
Net part area is the closed-outline area less holes. Part mass = net area × thickness × density. Layout placement uses a bounded bottom-left outline heuristic, not an optimal-layout guarantee.
Keep calculations inspectable
Inputs, units and results are shown together. Save a CSV or print the calculation to share your planning assumptions.

Which DXF files can I use?
ASCII, flat XY DXF outlines using LINE, ARC, CIRCLE, LWPOLYLINE and 2D POLYLINE. Closed contours are required. Explode blocks and convert splines/ellipses to supported polylines in CAD first. Curve flattening uses a 0.2 mm target tolerance. A disconnected drawing in one file is treated as one part. Part-in-hole nesting and common-line cutting are not performed.
Is unused material all reusable remnant?
No. The non-part balance includes the sheet skeleton, holes, spacing and potential offcuts. It is not a certified reusable-remnant quantity. A DXF layout export contains approximated polylines; verify geometry and toolpaths in your CAM software before cutting.
