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.
Chhena is a boundary entry, not a true ferment. Hot milk is curdled with citric acid, lime juice or another acid, and the soft curd is drained in muslin without pressing; no microbes do the work. It is the base of Bengali sweets such as rasogolla and sandesh. Made in 4 steps over 27 min – 30 min. The longest step, heat the milk, takes 7–10 min (Chakraborty P 2021) and runs at 70–90 °C (Chakraborty P 2021).
Amounts from a sourceAmounts are from one laboratory method (Chakraborty et al. 2021) for 500 g of milk. Home makers use the juice of one ripe lime for a pan of boiling milk.

What makes this one different
Chhena is curdled by acid and heat, not by microbes or rennet, so it is a boundary entry. Paneer is made the same way but pressed into blocks; chhena is only drained, which keeps it soft enough to knead into sweets.
Milk
Cow milk preferred; buffalo milk gives a harder, greasier chhena
Legal limits (India)
At most 70 % moisture and at least 50 % milk fat in dry matter, the same as paneer (FAO 1990)
Composition
Cow-milk chhena: 53.0 % fat in dry matter, 37.0 % protein (FAO 1990)
