Calculation method
Calculation method
Sequential roll cuts [cut length m,width m,count]
Add2seam to each panel dimension, choose feasible orientation with smallest cut length, lay one across roll at a time.
Required roll length (m)
Add2seam to each panel dimension, choose feasible orientation with smallest cut length, lay one across roll at a time.
Cut material area (m²)
Add2seam to each panel dimension, choose feasible orientation with smallest cut length, lay one across roll at a time.
Roll material waste (m²)
Add2seam to each panel dimension, choose feasible orientation with smallest cut length, lay one across roll at a time.

Assumptions & limits
Assumptions & limits
- Rectangular panel cutting only; no curved sail-shape nesting or multiple panels packed across width. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints.
