Shift Entire Point Clouds Elevation Data by Specific Number

in Elevation Data
Is there a way to sift the entire LAS point cloud elevation data by say 0.260 meters?? I have a point cloud that is consistently 0.26 m on average off in elevation. And need to shift it by that much in elevation any way to do this????

    There used to be a straight-forward way to do this but I can't find it now in GM v18 which makes me think it moved into the LiDAR module which I don't have. A cruder method would be to use CALC/COPY attributes to add 0.26 to the elevation of each point though that might be computationally intensive.

    Oh, i found it! Stumbled across the option looking for something else on some of my data. Once you have generated a surface, you can open the Options for that layer and use the "Alter Elevations Tab" to enter a vertical offset.
