I'd like to find the 3d distance between all points in two point feature classes. One is 12 000 building points, the other 22 000 point locations of a construction machine (along a line), constructing many km of tunnel. My aim is to be able to select the building points within x meters when the construction machine is at a specific location. How can I do this without running Near 3d several thousand times?
