At the top of the window is the text "Current working file:", followed by the full path name for the file.

Below that is a check box, with the instruction "Check to constrain TFI to a surface". In this example figure, the box is unchecked.

Next is a section with the instruction "Select Interpolation Mode", followed by three radio buttons labeled "Arc Length", "Semi-Arc Length", and "Index". In this example the first button is selected.

These are followed by a set of three more radio buttons, labeled "Generate default name", "Generate new name:" (followed by an empty text box), and "Do not write result - save in results buffer". In this example the first button is selected.

At the bottom are "Cancel" and "Select objects" buttons.
