Filter a Solid Model with One or More Boreholes

RockWorks | ModOps | Solid | Filters | Borehole Clipped Solid

Use this program to create one or more tunnels (or mine drifts) through a solid model, using borehole location coordinates and downhole survey information for the active boreholes in the Borehole Manager. Specifically, this tool defines the tunnel starting point as a borehole collar XYZ and then uses the downhole survey information in the Orientation tab for the tunnel survey.

This program can be used to either nullify the voxels outside or inside of the tunnel(s). For example, a tunneling operation could use this program to compute the volumes of various materials that are to be extracted from the tunnel(s). Conversely, a mining resource model could be subjected to a tube-filter whereby the mined regions, modeled by tubes, are removed from the model by setting the regions within the tubes to a null value. The graphic example above illustrates a single horizontally-trending borehole through a lithology model, which is viewed as a cloud of points with 5 north-south slices. The nullified interior nodes can be seen as holes in the panels and as the ghost trace through the points.

This program operates similarly to the Tube Filter option, except that it pulls the tube location(s) from the active borehole(s) in the Borehole Manager database rather than from a listing in the RockWorks datasheet.

• 3D Log Design
  If you decide to include logs with this diagram (3D Solid Diagram | Striplogs), click on this tab at the top of the window to set up how you want the 3D logs to look.
  See Visible Item Summary and Using the 3D Log Designer for details.

• Rules & Filters
  Use these tabs at the top of the window to apply spatial filters, time/date filters, or stratigraphic rules to data being displayed in your 3D striplogs. (More info)

• Input/Output Models
  • Input Model: Click to the right to select the name of the existing RockWorks solid model file (*.RwMod) to be filtered.
  • Output Model: Click to the right to type in the name to assign to the new solid model that the program will create, which results from the filtering operation.
  • 
    
• Options
  • Borehole Radii: Click here to type in the radius of the tubes in units that match the XYZ units of the solid model. For example, if your solid model units represent feet, then you would enter the radius of the tubes in feet.
  • Operation:
    • Choose Nullify Interior Nodes if all model nodes that lie inside the boreholes are to be set to a null value.
    • Choose Nullify Exterior Nodes if all model nodes that lie outside the boreholes are to be set to the null value.
  • Null Value: Use this prompt to define the replacement value for the filtered nodes. The default RockWorks null value is -1e27; you can enter this value or define a different replacement value.
  • 
    
• 3D Solid Diagram
  Insert a check here to display the output solid model as a 3D diagram.
  Click this tab to set up the diagram options.
  
  • Block Diagram
    • Isosurface: Click in the Isosurface radio button to display the solid model as if enclosed in a "skin." This view will be smoother than a voxel display. (More info)
      • Isomesh: Check this box to plot a series of polylines that represent three-dimensional contours at a user-defined cutoff. Click this tab to establish the settings. (More info)
    • Voxels: Click in the Voxels radio button to represent the solid model in the 3D display as color-coded voxels. You can choose to display either the Full Voxel, or just the Midpoint. Display of the midpoint only can significantly improve display time for huge models.
    • 
      
    • Filter: Check this option if you want to restrict the isosurface or voxel display to a specific data range. This does not affect the model, only the display of the model. Enabling this permits you to create an initial display in RockPlot3D that eliminates the need to manually change the display attributes. More importantly, this capability if essential for initially displaying the solid in a pre-filtered state when creating animations and Playlist scripts.
      ! These filter settings can be changed once the diagram is displayed in RockPlot3D.
    • 
      
    • Color Scheme: Choose the color scheme for the block model - automatic, table-based, etc. (More info)
    • 
      
  • Striplogs: Check this item to include 3D logs with the solid model display. Click the 3D Log Design button at the top of the window to set up how you want the logs to look.
    • XYZ Clipping: Check this sub-item if you want to restrict the logs to a particular spatial area. (More info)

  • Other 3D Solid Diagram Options: Use these checkboxes to append other layers to your 3D scene. (Summary)
    
    • Draped Image: Include an image in this 3D scene, draped over an existing grid surface. (More info)
    • Floating Image: Include an image in this 3D scene, floating at a specified elevation. (More info)
    • Perimeter Cage Include a 3D reference cage around the solid diagram. (More info)
    • Legends: Include one or more legends with the diagram.(More info)
    • Infrastructure: Display buildings, pipes, or other infrastructure with your 3D scene. (More info)
    • Faults: Include 3D fault ribbons with this scene. (More info)
    • Other 3D Files: Include other, existing, RockPlot3D ".Rw3D" files in this scene. (More info)
    • 
      
  • Output Options: Use these settings to define whether the output scene is to be saved (or displayed as "untitled"), how the file should be named, and whether it is to be displayed after it is created. It also offers export options. (More info)

Step-by-Step Summary

1. Click on the Borehole Manager program tab and be sure only those borehole(s) to be used to filter the solid model are currently enabled (shown with check-marks).
2. Select the ModOps | Solid | Filters | Borehole Clipped Solid menu option.
3. Specify the menu settings, described above.
4. Click the Continue button to proceed.

   RockWorks will read the contents of the input solid model file and compare the location of each of its nodes to the enabled boreholes, and replace the interior or exterior nodes (as requested) with a null value. The resulting solid model file will be stored under the declared output file name. If you have requested a diagram, it will be displayed in a RockPlot3D tab.

5. You can adjust any of the input options via the main Options tab to the left and then click the Continue button again to regenerate the display.
6. View / save / manipulate / print the image in the RockPlot3D window.
