Is 3d warehouse not working?

[DaveR]

The 3D Warehouse interface in SketchUp 2017 no longer works. You can search the 3D Warehouse using the Components panel or you can use your browser and download components to your computer to use in SU2017 Make.

See:

3D Warehouse in SketchUp 2017

Due to recent changes in the Chromium embedded browser, we are no longer able to support the embedded web dialog in SketchUp 2017 Make and Pro. You can still download from 3D Warehouse using an up-to-date browser like Chrome, Edge, Safari, or Firefox, or by using the Components dialog in SketchUp 2017. Thanks for your understanding.
