Assumptions & limits

Assumptions & limits

  • Rectangular cut panels, no polygon/window-hole optimization; input-order shelf proposal, not minimum sheets. 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. Rectangular cut panels, no polygon/window-hole optimization; input-order shelf proposal, not minimum sheets.
