Editing 3D tiles

Hi there.

Cesium newbie here. I am trying to understand the possibilities of Cesium.

I would like to recreate a view from my balcony either using Googles 3D Photorealistic Tiles or maybe with Vexcels 3D cities. Once I import these I would like to be able to edit them so I could cut out an existing block and import my own model. I would then like to capture these views using predetermined heights based off survey information (maybe this is possible in Blender).

Is this something I can achieve and if so any help would be greatly appreciated.

CesiumJS does support clipping regions. Is that the client you are using?

Please let us know if that helps.
