Surfaces rejecting borehole data
I have this organic material layer I'd like to model as an intrusion. Its in black. The boreholes are are oriented at about the same elevation, with 1 in the back and 4 in front here, with decreasing size of the organic layer.
When I model as an intrusion, I get the front leftmost and back boreholes to connect, but the two on the right won't join the party. I've added polylines to explicitly define my interpretation, but the software is plugging donut holes precisely where the black layers are. What in the world am I doing wrong?
open cutouts in the surface are due to intersection with the topography.
