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.
sauce-aroma baijiu, 53 % ABV; soy-sauce/roasted, long finish, low esters relative to strong aroma. Made in 7 steps over 4.2 years. The longest step, age and blend, takes at least 3 years (Xu S 2026). Bacillus licheniformis and Bacillus spp. do most of the fermenting.

Three Maotai distilleries merged into a state firm in 1951. A national tasting in 1952 named Maotai among four famous liquors. Sauce-aroma output was about 650,000 kL in 2024, and baijiu is classed into 12 aroma types.
