I am trying to create a surface in TBC that will match the surface created by a dual plane laser. The red point below is where the elevation is set (Bench elevation at this point is 100 ft). The laser is set up at 0.109% sloping down to the South and 0.549% Sloping down to the East. I thought this would be easier then it looks, but I'm having problem. Any ideas would be appreciated.
Use the create planar surface command.
