How to Surface Cut a grid to a horizon attribute.

Description:
After creating and saving a grid in Basemap plus on a 3D survey, how can I
copy the grid back to a horizon attribute.

Solution:
In Data Manager > Interpretation > Surface ...
1.)  Select Domain, Time or Depth.

2.)  Select survey in Define area, if 2D line, select 2D lines.
     Note:  Can change area of operation or choose a path on which 
     to operate surface cut.

3.)  Select surface and set Transfer mode to Surface grid => Horizon attribute.

4.)  Select the grid and type in the attribute name in the Name box beneath
     Attribute selection box. If this is time or depth data, input Z for the
     attribure name. But be careful, this will overwrite your existing Z values.

     and new attribute name in the Transfer list.  If you have made a mistake,
     highlight the line that you wish to take out and click on Remove. To 
     clear the Transfer list, click on Remove all.

     create a new attribute for that surface from the selected grid.
