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.
Like Parmigiano Reggiano but with a shorter minimum ripening (9 months), and lysozyme is allowed against late blowing.
Milk
Raw cow milk, kept at 8 °C or more, part-skimmed by natural creaming at 8–20 °C; lysozyme up to 2.5 g per 100 kg of milk is allowed against late blowing
Starter
Natural whey starter; native lactobacilli may be added when the whey is too weak
Setting
Calf rennet powder at about 35–40 °C; the curd is cut to rice-grain size
Cooking
Cooked to a maximum of 56 °C, then left under the whey for no more than 70 min
Moulding
At least 36 h in marking bands under a wooden disc
Salting
Brine for 14–30 days
Ripening
9 months from moulding at 15–22 °C; "riserva" means over 20 months
Size
Wheels of 24–40 kg, 35–45 cm across and 18–25 cm high; fat in dry matter at least 32%
