The Surface Options dialog appears when you import a file containing a surface. The file name is displayed in the dialog title. The options on this dialog apply to each individual filter if you turned off the Specify at Import toggle on the Text Import Wizard, Step 4 dialog.

If the toggle is turned on for any filter, all of the filters will use whatever parameter is provided in the Surface Options dialog at the time of each import.
