Microstation to Cesium tiles

Hi,

Today I red this article on the site of Cesium:

I think Cesium can be a very interesting way to publish big 3D city models and data on the web. The Cesium 3D tiles for example looks very useful.  

In the article I red that it is possible to convert MicroStation (next to Context Capture) 3De models to Cesium tiles.  I only can't find the way to do that.

Is it possible to post a / some tutorial(s) how we can use microstation to convert big 3D city models (with data) to Cesium (tiles)?

Thanks in advance,

Louis
