my 3d-tiles model is above the ground when i just use smart3d generated models and applications.

then I get the 3d-tiles branch from github and build it to get Cesiums folder to replaced old Cesiums folder which smart3d generated. in this situation my model was disappered.

Hi there,

Take a look at this thread: this thread: [https://groups.google.com/forum/#!searchin/cesium-dev/height$203d$20tiles%7Csort:relevance/cesium-dev/CqYeu6L6bhU/P0WywsBhBQAJ](https://groups.google.com/forum/#!searchin/cesium-dev/height%24203d%2420tiles%7Csort:relevance/cesium-dev/CqYeu6L6bhU/P0WywsBhBQAJ) , in which our resident 3D tiles expert Sean explains how to position tilesets.

Hope that helps,

- Rachel
