"Need models fast? SketchUp Pro 2016’s built-in 3D Warehouse gives you instant access to millions of user-made components — from furniture and fixtures to full building elements. Import directly into your project, check poly counts before adding, and use components to keep files light and editable. Share your own models too — just optimize geometry and add clear tags."
SketchUp Pro 2016 3D Warehouse today requires a manual workflow because direct in-app access is no longer supported. While the software remains functional for modeling, the integrated browser technology in the 2016 version is no longer compatible with the modern 3D Warehouse security and file standards.
