I am working with LAS files , but the files do not have any classifications (they all appear as Code 8 Model Key/Reserved) or when the classifications appear they are all classified as Code 2 ground. I have tried to change the classification codes, but the heights are too similar that it will classify buildings as ground. I have tried changing the classification codes, building a DSM, DTM, nDSM, but I have no polygons to extrude the buildings.

What are different ways to make lidar point cloud data 3D?

What is the horizontal and vertical projections of you lidar data?   It might be the xy is in geographic coordinates and the elevation is in meters or feet.   If so, you could use Extract Las and set in the environments to be a different projection for the horizontal projection.    I have run into this with one of the lidar datasets I processed into extract building footprints from.
