Hi!

I am trying to find a way to interpolate a TIN surface outside its extent. And if possible to the extent of a certain polygon. The image below shows an TIN created from LiDAR and the polygon of which I want the surface to extend to. The LiDAR does not have more points, but I would like to fill it in someway.

Any ideas? Thanks in advance!
