New: contour nesting for DXF and DWG — free during beta →

Cutting optimization — sheet cutting maps before the first cut

Castoro calculates straight cutting layouts and contour nesting for sheet materials. Import parts from Excel/CSV or DXF/DWG drawings, check the layout, and prepare cutting maps, labels and files for your workshop.

Contour cutting (nesting) for CNC

Shaped parts and holes for a router, laser, plasma or waterjet. Import your drawings and Castoro recognizes the contours, nests the parts on sheets and keeps usable offcuts for the next job.

  • Import DXF, DWG or a ZIP of drawings; you choose the cut and marking layers
  • Rotation, mirroring and priority per part, plus part spacing and sheet margin
  • Shared edges of neighboring parts can be cut once
  • Offcuts are kept as contours and go back into the project sheets; a sheet can come from DXF too
  • Results in DXF and DWG for the machine, plus SVG, PNG, PDF, Excel and a share link

Contour cutting is free while it is in beta. Try it on your own drawings and tell us what is missing: your feedback decides what we build next.

Who Castoro is for

  • Furniture manufacturers and joinery workshops
  • Glass and mirror companies
  • Metalworking and signage production
  • Small production teams and workshops
  • CNC shops: routing, laser, plasma and waterjet cutting

What Castoro helps with

See how to cut

Get visual cut maps with parts, offcuts, and waste before material goes to the saw.

Reduce manual entry

Import part lists from Excel/CSV, paste from spreadsheets, or enter dimensions manually when the order is small.

Check the sequence

Play the cut order step by step and hand a clearer workflow to the operator.

Keep production details

Account for grain direction, edge banding, saw kerf, sheet margins, and export the result for the workshop.

What you can do in Castoro

  • Optimize cutting for chipboard, MDF, plywood, glass, metal, and other sheet materials
  • Nest shaped DXF and DWG parts on sheets for a router, laser, plasma or waterjet (contour cutting, beta)
  • Keep contour offcuts and export layouts, parts and offcuts as DXF and DWG
  • Import part lists from Excel/CSV or paste spreadsheet data from the clipboard
  • Compare several layout variants by waste, cut count, and production metrics
  • Open interactive cut maps with zoom, parts, offcuts, and waste areas
  • Manually edit layouts: move parts between sheets, offcuts, and unplaced items
  • Play the cut sequence step by step before starting production
  • Account for grain direction, saw kerf, edge banding, and sheet edge offsets
  • Enter finished part sizes and get the blank with edge banding and premill accounted for
  • A warning in the table when edge banding shifts a finished size
  • View a part in 3D with its edge banding, grain and dimensions
  • Share screenshots, links, table data, or generate a PDF report when needed
  • Put PDF sections in your order: each sheet map stays with its table, labels stay last
  • Print part labels with sizes, material, edge banding and a QR that opens the part card
  • Cost material and edge banding and add the estimate to the PDF
  • Search and filter calculations in history, rename them and open them again
