CLI command design

download-part

Fetch one EasyEDA / LCSC component API response by C-number and write a local bundle containing raw JSON, summary JSON, 3D model metadata, and requested 3D model files.

Usage

easyeda-monkey download-part C21190
easyeda-monkey download-part 21190 --output-dir parts
easyeda-monkey download-part C21190 --model-format step --cache-dir .cache/easyeda

Arguments

Name Required Meaning
lcsc_id Yes LCSC C-number. The command accepts either C21190 or 21190.
-o, --output-dir No Output root directory. The command writes into <output-dir>/<LCSC_ID>/. Default is output.
--cache-dir No Directory for cached raw API responses. A matching cache file avoids live API access.
--model-format No One of both, step, obj, or none. Default is both.
--timeout No HTTP timeout in seconds for live API requests and 3D model downloads.
--rate-limit-seconds No Minimum delay between live API requests made by this process.

Output

The default output directory is output/C21190/ for part C21190. The bundle is intentionally file-oriented so users can inspect the raw API data and the downloaded model files without writing Python.

Path Meaning
easyeda-api.json Raw EasyEDA / LCSC API response.
summary.json Compact summary with symbol, footprint, and 3D-model counts.
3d-models.json Extracted 3D model references and source URLs.
models/<uuid>.step Downloaded STEP model when requested.
models/<uuid>.obj Downloaded OBJ model when requested.
download-report.json Machine-readable report listing output paths and download success.

Config And Contracts

This command has no config file. Its JSON report is useful for automation, but it is not yet promoted to a stable output contract.
