Hi,

 

 

Use the PointCloudCombiner to join/merge the datasets.

 

You can assign the z value to the lines by a spatial test  (SpatialRelator) and z value mapping.

if any points coincide with the line, or are within a tolerance, you would have to assign the z value to the nearest line vertex ( that is assuming your line has more that the start and end vertices).
