Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Wheel 34–38 cm across, 8–11 cm high, 8–10 kg; fat in dry matter ≥50 %, moisture ≤44 %; orange-brown rind. Made in 5 steps over 2 months. The longest step, ripen on wooden boards with rind care, takes at least 2 months (Domanda di registrazione 'Stelvio/Stilfser' 2005). native aerobic surface bacteria that colour the orange rind does most of the fermenting.
