- Worth noticing
- Finite-sheet results count only complete holes; the page separately shows an infinite-pattern open-area reference.
Field notes
The interface separates parameter entry, a pattern preview, and calculated results. Inputs include sheet length, width, and thickness; hole geometry, pitch, and orientation; arrangement; and material. Results are described as based on complete holes inside the sheet boundary, while the page warns that densities, coatings, burrs, and production tolerances can affect actual weight. Zoom, hole-detail, and PDF-download controls are also present.
