This is a bar bending schedule tool for civil/structural construction sites. It features a light-colored "engineering card workbench" design, supporting bar bending entry, graphic library lookup, diameter-based summarization, and text export. Calculations follow BS 8666 form specifications (bending deduction, hook increment, d²/162 unit weight).

Functional Modules:

Bending — Card-based information flow, including graphic preview, diameter, number of bars, cutting length, and weight.

Graphics — Explanation of 6 standard forms and cutting formulas.

Summary — Total weight, itemized statistics, progress bar by diameter, copy bar bending schedule.

Edit — Full-page form with real-time graphic preview and cutting/weight calculation.
