NestCut Cutlist Optimizer
2D rectangular nesting that packs parts onto stock, draws a cut diagram per sheet, and reports yield.
Sheet Metal Nesting Calculator
Pack your parts onto sheet and plate to minimize scrap. Enter your stock, your parts, the kerf, and whether parts can rotate, and the tool nests them, draws a landscape cut diagram per sheet, and reports material yield. Bin packing is NP-hard, so the layout is a strong approximation, not a proven optimum.
Kerf is the material removed by each cut; it is added as spacing between parts. Edge trim reserves a clean-up margin around the sheet. Lock a part's orientation (for grain or a directional finish) by unchecking Rotate on that part.
The sheets or plates on hand. Quantity is how many of that size you have; check Unlimited to treat a size as effectively endless. Stock is used top to bottom, so drag a row by its handle (or focus it and use the arrow keys) to set your preferred order.

The parts to cut, in the same units as your stock. Uncheck Allow Rotate to keep a part in a fixed orientation.

Bulk paste parts (CSV)
One part per line: label,width,length,qty,rotate. The rotate column is optional (1/0, default 1). Example: Bracket,12,8,20,1
Method: offline 2D rectangular bin-packing (Maximal Rectangles, Best-Short-Side-Fit) with optional 90° rotation. Bin packing is NP-hard, so the layout is a strong approximation, not a proven optimum. Results are deterministic for a given input.
