How it works
Expand requested quantities, sort pieces longest first, and place each in the first existing stock that fits. Include one kerf between adjacent pieces; otherwise start another stock.
Input definitions

- Plain text; maximum 200,000 characters.
- Stock length (whole mm)

Common questions
Is this cutting plan guaranteed to use the fewest stock lengths?
No. It uses first-fit decreasing, a fast packing heuristic. Compare layouts and allow for end trim, grain direction and actual cutting practice before ordering.
