I have a point file with elevation data. Some of the points are elevations relating to soil horizons.
I've created a TIN surface for each soil horizon then used the "extrude between" tool to create a 3D polygon of the area between each surface, basically creating a set of blocks stacked on each other representing the different soil horizons.
I now want to select points that fall within each soil profile. However, my multipatch is not closed so using the tool "inside 3D" does not give me all the points that fall inside each soil profile. I have about 5 different profiles, one of which is closed and the others are not. I've tried the "enclose 3D" tool but it adds volume in the z direction, misrepresenting the soil profile.
Why is the extrude between tool not enclosing all multi-patches and how can I fix this?
