I have three layers:
I imported them all into CityEngine and I aligned parcels and Buildings to Terrain (DEM).
I notices that, in large parcels (see Figure 1), some buildings are floating. The reason is, the large parcel vertices have been aligned to terrain. But the middle part of the parcel has a higher height. When I align the building to the terrain, it aligns it to terrain based on the height of that area. Accordingly, it keeps the building in a height floating.
What would be the best method for fixing this issue?
