CADENAS PARTcommunity / 3DfindIT
Provider：CADENAS GmbH
CADENAS free manufacturer-certified 3D CAD catalog portal (PARTcommunity/3DfindIT): 7,500+ catalogs, millions of models, native CAD and STEP download.
At a glance
- Readiness
- L1 · Rigid-body ready
- Rationale
- Manufacturer-certified catalogs with vendor-verified geometry; some models carry kinematic mates and digital-twin metadata, but coverage is mostly rigid-body geometry with incomplete mass/inertia, so L1.
- Scale
- 3DfindIT aggregates 7,500+ certified manufacturer catalogs in 100+ CAD/CAE/BIM formats; the free PARTcommunity portal offers 400+ catalogs and millions of 2D/3D models. (3DfindIT is the successor brand to PARTsolutions; figures from CADENAS official and 3DfindIT pages, checked 2026-10-25.)
- License
- Proprietary but free — Catalog models are free to download for engineering use; native CAD and STEP models ship under each manufacturer terms — no resale or redistribution; enterprise PARTsolutions is paid.

Why it is listed
PARTcommunity and its successor 3DfindIT are the largest free portals for manufacturer-certified 3D CAD models, directly relevant to building simulation-ready digital twins: engineers pull verified geometry instead of modeling from 2D catalogs.
Readiness assessment
Every model is verified by the supplying manufacturer and exported in native CAD formats (CATIA, SOLIDWORKS, Creo, NX, AutoCAD, Solid Edge) plus neutral STEP. Many components also carry special kinematic mates and rich metadata, so they behave as lightweight digital twins rather than bare meshes. Mass and inertia are model-dependent and not guaranteed, placing the library at L1 as a rigid-body geometry source.
Practical notes
Discovery supports geometric similarity and sketch search, and a free plugin integrates models into the host CAD system. Because each catalog keeps its own license, verify per-model terms before reuse; the portal is free for engineering evaluation but not a redistribution source.
