When generating CAD points from a point cloud, and specifying "Snap to Lowest", what is the "Interpolation Radius" and how does changing it affect what point is selected? For example, I created a point cloud using High Reconstruction and I want to pull out the lowest points on a 30 foot grid spacing to obtain ground surface points around sparsely spaced trees and shrubs. The prompt defaults to an Interpolation Radius of 3 ft. What happens in that 3 ft radius? Thanks.

Hi Steve,
Interpolation radius of 3 feet simply meanis that the height of the generated point will be the mean height of points that are in radius of 3 feet around the point that is being calculated.
If snap to lowest checkbox is enabledd, then the height of point will be the lowest point in the radius of 3feet.
