New methods have been added to Surfer to show the base on 3D surface layers!
You can now select three different Z value settings to define to what Z value the base is shown. Previously, the base for the 3D surface layer filled the sides from the surface down to the minimum Z value of the grid file. Now you can select to show the base from the surface down to the minimum Z value in the map, to the minimum Z value in the grid, or to any Z value that you specify.
