Merging two terrains surface

[billg60]

I am trying to model the terrain of my property. I have a detailed contour map of the area around my home to be but I have to resort to google maps terrain for the remainder of the 13 acre area. I want to merge these two surfaces together using the more accurate survey where available. I think I need to cut a hole in the google earth mesh for the perimeter of my pad survey and then need to stitch the two together. I have struggled with how to do this for some time so ideas on strategy would be appreciated. [img]2017-04-23%2008_03_06-Site1.11.skp%20-%20SketchUp%20Pro%202017.png[/img]

Seems native Tool Sand Box will be your friend!

My "Clip or Trim Terrain Mesh" should do that for you.
