If your file has been recognized as a Dfs2 result file you will be prompted for the contour item and vector item that is to be plotted. You also have the possibility to plot derived items as e.g. surface elevation and velocities.
NOTE: The calculations of derived items are based on the assumption of the absolute delete value being very small, e.g. -10-30. The use of other delete values may lead to incorrect derived results in grid cells next to cells holding delete values.
