LCSC MODEL RESOLVER

LCSC 3D Model Downloader
Original OBJ and STEP / STP files

No developer tools required. Paste an LCSC product page to resolve its EasyEDA component model and download the original OBJ mesh or solid STEP / STP source whenever it exists.

Tracking parameters are removed before the canonical product page is requested
01

Canonical URL cleanup

Removes tracking parameters that can trigger the WAF and keeps only the numeric item ID.

02

Original STEP first

Downloads the upstream STEP AP214 solid when available instead of disguising a triangle mesh as CAD.

03

Server-side safe resolution

Only fixed LCSC and EasyEDA hosts are contacted; arbitrary proxy requests are rejected.

HOW IT WORKS

How do you download an LCSC 3D model?

LCSC product pages normally show an interactive 3D preview without a conventional file download. This LCSC 3D model downloader reads the product code from the item page, then resolves the matching EasyEDA package UUID and 3D model UUID.

You can download the original OBJ mesh after resolution. If EasyEDA stores a CAD source exported by tools such as SolidWorks, the original STEP / STP AP214 file is offered as well. Models without a source STEP are clearly marked instead of being converted into a low-quality faceted file.

FAQ

Frequently asked questions

Which LCSC links are supported?

The supported format is https://item.szlcsc.com/number.html. Search, referral and fragment parameters are removed automatically.

Is the STEP file converted from OBJ?

No. The downloader prefers the original STEP source stored by EasyEDA, preserving solid B-rep data. STEP is marked unavailable when no source file exists.

Can I use the downloaded model commercially?

The files come from public LCSC and EasyEDA resources. Permission for a specific commercial use depends on their applicable terms and the rights attached to the model.

Why are some products missing 3D or STEP files?

Not every component has a drawn 3D package, and not every 3D package has an original STEP source. The site only exposes files that are actually available upstream.
