Generate 0 contours?

I imported a DT2 file in GM but I couldn't have the zero profile with "Generate Contours" tool because GM said "No contours at specified interval in region of interest".
How can I do?:confused:
Thanks.

    Global Mapper only generates contours when the elevation pass down through an elevation to a lower elevation. So if your data flattens out at 0 and never goes below that you won't get a 0 contour. What you can do instead is generate a single contour value at just above 0, like 0.01, then you'll basically get what you are after.

    Let me know if I can be of further assistance.

    Thanks,
