I am having trouble creating a Digital Elevation Model (DEM). I need to need to take my ground points and move them all to the same height, while keeping my higher points (vegetation) in their same X,Y coordinates. I have not been able to find how to do this throughout videos and other forums. Any help would be much appreciated.

Hum, do you already know what are your ground points? If yes, then if you can make a separate cloud with them (generally with the 'Edit > SF > Filter by value' tool), then you can:
  • add a 'constant' scalar field to this cloud (Edit > SF > Add constant SF) - set the unique value to the target height of your ground points
  • convert this scalar field to the Z coordinate (Edit > SF > Set SF as coordinate(s))
  • merge this cloud with the vegetation cloud
