Thanks for the example--that seems to work fine for what I want to accomplish.  I currently have a 2D version (not using Powertoys) where I triangulate the point cloud and use the triangles and vertex elevations to return elevations at any arbitrary point within the cloud. I also use the triangulation to calculate contours.  I'm hoping to do all of that with Powertoys in 3d.  I am assuming I can also somehow return the elevation of any arbitrary point within the heightmap with Powertoys directly.    I also wanted to turn off the wirebox axis', and there is checkbox for that in the example, but it didn't seem to work. You could turn of the scale, but not the wirebox.  I know you can do that from your other examples, so that part is just FYI.  Thanks very much for your time.
