How to cut the 3d model and tile models

[saduka]

Hi all:
I have lots of tilted aerial urban images, the 3d tile model of which is very bad on the four edges.
I want to cut them out by some means. Is there someway to do this? Such as defining an area of interest  or  resetting the bounding box through geographic coordinates.
much obliged

Hello saduka,

You can create a planar polygonal shape with XY coordinates of the vertices, set the outer boundary type for it and enable clip_to_boundary option on export.
