For my first Roundup-inspired post, I picked a topic that every explorer I meet is interested in – working more effectively in 3D.
Displaying drill holes in 3D using DH-Plot > 3D Map is a convenient way to create a 3D map, complete with a legend, showing selected holes, topography, and two types of data. Here, as may often be done in a 2D section, lithology has been plotted as a Rock pattern and gold assays are displayed as a Bar plot. It is easy for this to become cluttered, making it hard to see significant characteristics in your data.
In order to start from a cleaner, less cluttered view of your data, try this instead:
1. Use DH-Plot > 3D Map to create the 3D map of the selected holes in the drillhole project, but leave the Data tab blank. For an even cleaner starting point, try turning off the "Depth Ticks".
2. In the 3D Viewer, select the Add to 3D > Drillholes menu option. Instead of plotting the geology as a Rock pattern, display only important geological intervals using discrete values in a Text band.
Discrete intervals in the Number bands option is also a good way to display significant ranges from assay results.
3. In order to display other types of data using the Add to 3D > Drillholes menu option, first rename the existing group. Then you can toggle this layer on and off as you build your 3D data groups.
Now use the Add to 3D > Drillholes menu option to add more geology intervals or other downhole data.
4. Finally, add the Topography grid to help orient your 3D view relative to the surface.
