Pieces can rotate when that packs more. • 3D packing — Pack boxes into a container. Drag to orbit, pinch to zoom, double-tap to reset. Select a box to pull it out, undo, or show all again. • Desi calculator — Cargo desi, volumetric weight, and chargeable weight. Road (3000) and air divisors, or your own. With the outer container off, pieces stack on the floor (e.g. 5 pieces as 3+2). With it on, they pack inside the box. Inner solids can be a box, cylinder, or cone; desi always uses the bounding box (diameter × diameter × height). Cargo desi stays separate from the stack envelope and container desi. Select/pull-out is only when the outer container is on; you get solid volumes plus a wireframe shell. • Spacing — Even marks along a perimeter or edge, with optional corner pinning. • Cubic meter / concrete — Length × width × height, or a cylinder (diameter × height). Each edge can be mm, cm, or m, mixed. Quantity and waste % (0 / 5 / 10 or custom) give net and order m³, liters, and cm³. Rough mix presets: C16 1:2:4, C20 1:1.5:3, C25 1:1:2, or custom parts; cement, sand, aggregate, and 25/50 kg bags (rounded up). Mix figures are a site rule of thumb, not a structural design. • Shortcuts — “Custom tools” is now a home page and shortcut target on the Appearance wheels. The top-bar swap control also works on the custom hub and its child screens. Still free, with no ads and no account. History and preferences stay on your device. ### 2.9.0 — 2026-09-14 This update adds Custom converters: packing, cargo desi, and construction cubic meters next to your everyday calculations. • 2D packing — Fit smaller pieces into a larger area and see filled vs. empty space.
