9 · Bill of Materials quantities from design · prices editable
Quantities are derived from the calculated design (incl. ~5 % core cutting allowance). Unit prices are indicative supply-only USD values — edit them to your actual quotes; edited prices are kept when the design recalculates. The Excel file contains live formulas (Amount = Qty × Price, auto-summing total) plus a second sheet with the full design data. The BOM is issued in Excel only — not in the PDF report.
