These two interbed tabs provide an interface for editing interbeds. In the spreadsheet to the left, interbeds can be added and removed. Also, the interbed's model layer can be set. The array spreadsheet to the right behaves similar to other areal spreadsheets. To edit a particular interbed array, select the row for the desired interbed in the spreadsheet at the left, and then select the desired array from the View/Edit combo box. The 2D Data Set -> Array button can be used to set the viewed array values to a 2D data set provided the 2D grid has the same number of rows and columns as the 3D grid. The Array -> 2D Data Set button can be used to copy the viewed array to a 2D data set; the same grid size limitations apply. The Constant -> Array button can be used to set all of the values in the viewed array to the same value. | |||
