The 3D Warehouse no longer supports direct access from within the 2016 application. Users must download models via a web browser and import them.

Supports Windows 7/8/10 and Mac OS v10.9-10.11. It is noted for supporting 32-bit Windows, unlike newer versions.

Features a 3D warehouse, LayOut for 2D documentation, and specialized Cartesian axes (red, green, blue).

While 2016 is older, users with a valid "classic" license can still activate it, though licensing servers may be unreliable for this version. Important Considerations for Older Versions Help with 2016 pro version - SketchUp Forums
