Create distance "buffer" in textured model

[smiller]

Hi everyone,

I am wondering if it is possible to create a "buffer" around a center point in my models and then have the portion of the model that is not included in the buffer to either be hidden or deleted (or it could be highlight and then I would go press the X icon to delete the selected sections outside the buffer circle). I am not seeing a way this is possible using the GUI, so would this require some python scripting? I want to measure the surface area of these models but have them be consistent with a specific radius from the center point. My models are georeferenced.

Any help would be greatly appreciated!
