Convert Total Ore Thickness to a Grid Model

RockWorks | ModOps | Solid | Extract Grids | Total Ore Thickness Grid

This program translates a Boolean solid model file representing "ore" versus "not-ore" into a 2-dimensional grid file that represents total ore thickness, in real number values, for display as a contour map, 3D surface, etc.

Feature level: RockWorks Basic and higher

Step-by-Step Summary

Menu Options

• Input/Output
  • RockWorks Solid Model File (Input): Click to the right to browse for the name of the existing RockWorks solid model (.RwMod file) that the program is to read, containing the "ore" versus "not-ore" voxel values (values of "1" versus "0", respectively).
    ! This must be a Boolean (not a real number) model. See the Applying a Boolean Filter to a Solid Model option for information.
  • 
    
  • RockWorks Grid Model file (Output): Click to the right to type in the name to assign to the new grid file (.RwGrd file) that the program will create. The real number grid model will represent the total thickness of the "ore" nodes within the input solid model file.
  • 
    
• 2D Grid Map: Insert a check here to create a 2D map of the output grid model. Click on this tab to set up the 2D map layers (bitmap, symbols, labels, line contours, color-filled contours, labeled cells, map border, etc.).
  ! Don't request map symbols or labels if you don't have any data loaded into the RockWorks datasheet at this time.
  • Output Options: Use these settings to define whether the output graphic 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)
  • 
    
• 3D Grid Diagram: Insert a check here to create a 3-dimensional image of the output grid model. Click on this tab to set up the 3D map layers (surface style, colors, perimeter, reference cage, etc.).
  • 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. Be sure you have an existing Boolean solid model already created, for input into this program.
2. If you want to include your control point symbols on a 2D map, you'll need to create or open a listing of these X and Y locations.
   ! Tip: Use the Borehole Manager's File | Transfer | Locations -> Datasheet to transfer a listing of your borehole location data to the datasheet.
3. Select the ModOps | Solid | Extract Grids | Total Ore Thickness Grid menu option.
4. Enter the requested menu settings, described above.
5. Click the Continue button to proceed.

   RockWorks will read the input Boolean solid model file, and for each column of node values it will compute the total thickness of "ore" nodes (which are assigned a Boolean value of "1"). The total thickness, expressed in your original elevation or depth units, will be stored as the Z value for that X,Y node location in the output grid file. This process is repeated for each column of nodes in the source file. The completed grid file will be stored on disk under the requested file name.

   The requested diagram(s) will be displayed in a RockPlot2D tab and/or RockPlot3D tab in the Options window.

6. You can adjust any of the settings via the main Options tab to the left, and then click the Continue button again to regenerate the diagram(s).
7. View / save / manipulate / print the diagram in the RockPlot2D and/or RockPlot3D window.
