    Hi Maarten,

    There is not a way to extract the convex hull polygon from the gridding process, or generate it another way in Surfer. I have added your vote to this request on our suggestion file! Our Didger and MapViewer software packages can generate the convex hull polygon. If you have one of those packages, you can generate the polygon and export it to a BLN file for use in Surfer.

    Thanks,

    Kari
