I have 2D lines and blocks (with different proper layer names) and 3D points with different wrong layer name, those lines pass by those points in plain view , so they share X and Y with the points but the elevation is different, can you please help with a lisp program to change the layer names of these points to making it similar as the passing line or block.
(as u see in the attached picture the points is showen as X)
