topic Visualize the 3D geology using drilled borings in ArcGIS Pro Questions https://community.esri.com/t5/arcgis-pro-questions/visualize-the-3d-geology-using-drilled-borings/m-p/1410221#M81887 <P>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.&nbsp; 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?&nbsp; Ultimately, I would like to create geologic surfaces, volumes, and/or a voxel layer depicting a buried sand aquifer. Thank you for any insights.</P> Tue, 16 Apr 2024 13:42:44 GMT GJB 2024-04-16T13:42:44Z Visualize the 3D geology using drilled borings https://community.esri.com/t5/arcgis-pro-questions/visualize-the-3d-geology-using-drilled-borings/m-p/1410221#M81887 <P>In ArcGIS Pro 3.2.1, I would like to visualize subsurface geology based on geologic contacts determined from well borings.
