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.
Raw cow milk, sometimes partly skimmed, is seeded with natural starters and set with calf rennet at 31–34 °C. The rice- to maize-size curd is cooked to 51–55 °C, pressed at least 5 hours and brined. The wheel spends at least a week in a cold cellar and at least 21 days in a warm cellar, where the eyes form, and leaves the cellars no sooner than 75 days after making.

Raw cow milk, sometimes partly skimmed, is seeded with natural starters and set with calf rennet at 31–34 °C. The rice- to maize-size curd is cooked to 51–55 °C, pressed at least 5 hours and brined. The wheel spends at least a week in a cold cellar and at least 21 days in a warm cellar, where the eyes form, and leaves the cellars no sooner than 75 days after making. Made in 10 steps over 30 days. The longest step, form the eyes in a warm cellar, takes at least 21 days (Cahier des charges de l'indication géographiq…) and runs at up to 25 °C (Cahier des charges de l'indication géographiq…). Natural starters and thermophilic lactobacilli; the group holds references for the strains specific to this cheese does most of the fermenting.
It must be made from raw milk with natural starters, where its 1996 summary still allowed thermised milk, and the curd may not be washed. It ripens at least 75 days, including at least 21 days in a warm cellar.
Milk
Raw cow milk only; the coarse fodder comes entirely from the area
Ripening
At least 75 days from making to leaving the cellars
Size
Wheel 72–80 cm across, 14–32 cm high, at least 60 kg; fat at least 28% of the finished cheese, dry matter at least 62% at 75 days, salt at most 0.4 g per 100 g
The milk stays raw, so the specification limits storage to 36 hours at 8 °C or less (48 hours at 4 °C or less) before renneting. The US FDA says ageing raw-milk cheese for 60 days may not remove E. coli O157:H7 and Salmonella, and Listeria may grow in certain cheeses during ageing. The CDC says people at higher risk, including pregnant women, people 65 or older and people with weak immunity, should avoid cheese made with raw milk unless it is heated to 165 °F (74 °C) or until steaming hot.
Cheese dairies (fruitières) made Emmental in Savoie from the start of the nineteenth century; the 1996 summary counts over 400 such dairies in 1908. The original 1996 rules allowed raw or thermised milk and a 70-day minimum; the current specification requires raw milk and 75 days.
