In ArcGIS Pro 3.2.1, I would like to visualize subsurface geology based on geologic contacts determined from well borings. The attached figure shows what I'm trying to recreate but so far no luck. I imported my table with geologic contact elevations and created a point feature. The points (borings) plot as desired on the ground surface but how do you extrude to negative subsurface values? Ultimately, I would like to create geologic surfaces, volumes, and/or a voxel layer depicting a buried sand aquifer. Thank you for any insights.
