I have 20 some lidar files with over 70 thou. points in each.. I need to find a way to correct an error in them. They must move a small amount in N,E, and Z direction. Anyone have any idea's ...

I have tried.

Inserting them into excel but am limited to 69 TH points... I could do it this way but some files have over 1.3 M points. I would have to create way to many smaller groupings for each and introduce many errors.

Inserting them into CAD and selecting sections at a time but it crashes.
Does anyone know if CAD is limited to selecting a certain number of entities or should this be able to work?

I have thought about limiting the sample number of points but would like to use every point if possible.
