For discoverability, let's create the following Sandcastle examples:

3D Tiles - Photogrammetry
3D Tiles - CAD
With an indoor and outdoor example
3D Tiles - Point Clouds
These can be pretty simple examples with data from cesium.com, and will supplement the other examples.

Also include a city/pickable buildings type demo.

Also include a city/pickable buildings type demo.

We could use the NYC data for this, I also think it's important to show off this type of dataset because of styling.

The current "3D Tiles Batch Table Hierarchy" Sandcastle example reports:

This tile uses a lowercase refine "add". Instead use "ADD".

Same comment for other 3D Tiles Sandcastle examples.

Also at least some of the 3D Tiles Sandcastle examples should be labeled "Showcases" so they show up in the default tab.
