I’m not sure how other software does this, but I presume they must have the ability to exclude the project area from the 3D tiles visualisation.

It looks very strange to have the existing situation (for example a building that must be demolished) showing overlapping with the design models.

I’d expect to be able to define a polygon (on the 2D horizontal plane) that acts as a clipping mask or something. Could be a 3D volume as well it that is easier to implement, as long as that object then can be hidden.

Hi @Johan_De_Cock,

Fair point! We’ve actually already implemented an internal version of this, allowing you to define or select a polygon to clip away a section of the 3D tiles. We’re still working on a more extensive user interface to manage these tilesets (including loading other tilesets besides Google Maps), and this will include defining cutout polygons.
