3DPaintBrush has an inbuilt integration with Google 3D Warehouse. You can search and download models from the largest 3D models repository in the world directly from within 3DPaintBrush.

Having access to such a large collection of 3D data can help you ideate and customize your 3D scenes for specific purposes. In the tutorial below, I create a simple scene by searching for a chair, a table, a vase and 3D walls. The copy/paste components, as well as move, scale and rotate components functionality is also shown. I also modify the material properties of these components inside 3DPaintBrush.

Have a look!
