Creating a Section Diagram of Multiple Grid Models

RockWorks | ModOps | Grid | Section

This program is used to create a single- or multi-panel cross section cut through multiple existing grid models, for display as a line section diagram. The names of the grid files are read from the current datasheet.

Feature Level: RockWorks Basic and higher

Step-by-Step Summary

Menu Options

• Rules & Filters
  Use the tabs at the top of the window to apply spatial filters, time/date filters, or stratigraphic rules to data being displayed in your logs. (More info)
• 
  
• 2D Log Design
  If you decide to include logs with this diagram ("Striplogs" setting, below), click on this tab at the top of the window to set up how you want the 2D logs to look.
  See Visible Item Summary and Using the 2D Log Designer for details.
• 
  
• Section Location
  Click on this tab to draw, on a map display of your enabled boreholes, where the cross section cut is to be placed. The most recent section drawn for this project will be displayed. (More info.)
  ! If you don't have boreholes in your project, there won't be any reference information in the selection map - just a rectangle defining the project dimensions. You may need to manually specify the panel coordinates
• 
  
• Location Map
  Check this box to create, along with the cross-section, a reference map that shows the section trace's location. It can be embedded in or created separately from the cross-section. (More info.)

• Data Columns: Click on this tab to define the names of the columns in the datasheet which contain the data to be read by the program.
  • Grid Files: Select the name of the column in the datasheet where the names of the grid files to be represented in the section display are listed.
  • Line Style: Select the name of the datasheet column where the line style for each grid's cross section is listed.
  • 
    
• Vertical Exaggeration
  Click here to pre-define the vertical stretch you would like to apply to your diagram. By giving the program this information in advance of generating the section, it can help with text and graphic sizing and placement. (More info.)
  ! Note that you can always change the vertical exaggeration at which the diagram is displayed, in the RockPlot2D window itself. But, by telling the program up-front how stretched it will be, you'll get better placement of the graphic components.
• 
  
• Traverse Defined By...: Use this setting to tell RockWorks how you want to define the cross section location.
  • Interactive Map: Choose this to draw or import the section location in the Section Location tab at the top of the window.

  • 

  • List of Borehole Names: Choose this option if you have created a text file in which you have listed the names of the boreholes to be represented in the cross section, one name per line in the file. Example:

    DH-30
    DH-03
    DH-21
    DH-40

  • List of XY Coordinates: Choose this option if you have created a text file in which you have listed the X and Y coordinates for the cross section vertices, one space- or tab-separated coordinate pair per line. Example:

    481896.8 4399952.0
    481953.3 4399923.8
    481997.6 4399898.1
    482031.0 4399892.9

• Section Attributes: The program will read the line style, thickness, and color from the datasheet. However, you can set up the line smoothing and other attributes by clicking on this tab. (More info)

• Striplogs
  Check this box to include 2D striplogs with your section diagram. This requires that you have data entered into the Borehole Manager database. Click the 2D Log Design button at the top of the window to set up how you want the logs to look. Click on this tab to establish some additional striplog settings.
  
  • Clip: Check this box if you want to display a subset of the log data. Click on the tab to define the elevation range to be displayed.
    • Top Elevation: Enter the uppermost elevation to be displayed in the logs.
    • Base Elevation: Enter the lowermost elevation to be displayed in the logs.
      ! Log clipping parameters are defined using elevations, not depths. (More info.)
  • Save Log List: Check this to save to a text file the names of the boreholes that are included with the profile diagram.
    • File in which to store the Log List: Enter the name for the log list text file.
    • Display List Upon Completion: Check this to display the text list in Notepad (or equivalent) after the profile is completed.
• Annotation
  Click on this tab to establish title, border, axis labels, and other perimeter settings for the section. (More info.)

• 

• Faults
  Check this box if you want to display lines in the output diagram where the section slice intersects the fault(s) defined in a project Faults Table.
  Click on this tab to set up the fault lines. (More info.)

• 

• Infrastructure
  Check this box to display buildings, pipes, or other infrastructure with your cross section.
  Click this tab to define the infrastructure file and plot settings. (More info)

• 

• Other 2D Files
  Check this option to include existing RockWorks profiles as layers with your section.
  Click on this tab to select the existing graphics (.Rw2D files) to be included. (More info)
• 
  
• Peripherals
  Check this option to include various peripheral annotations with your cross section. Options include titles, text blocks, pattern legends, and more.
  Click on this tab to activate the items and establish their settings. (More info)
• 
  
• Border
  Check this option to include a solid line border around the entire section image.
  Click on this tab to establish border settings.
• 
  
• 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)

Step-by-Step Summary

This program requires that the grid models to be illustrated as a cross section already exist in the current project folder.

1. Access the RockWorks Datasheet program tab.
2. Create a new datasheet and enter, import, copy-paste the listing of RwGrd files and line styles to be used to create the section diagram. You can use the Columns | Column Properties menu option to define the column styles - file names, line styles, symbols, etc.
   Or, open one of the sample files and replace that data with your own. See Data Layout for datasheet examples.

   ! Click the Example button at the top of the window to load a sample file that is installed with the program.

3. Select the ModOps | Grid | Section menu option.
4. Enter the requested menu settings, described above.
5. Pick the section: If Traverse Defined By is set to Interactive Map, click on the Section Location tab to set the location of the section panels.
6. Click the Continue button to proceed.

   The program will look at the coordinates specified for the secton cuts and determine the closest nodes along the cuts in the input grid models. It will construct a vertical section diagram to illustrate the grid surface elevations, using the line styles you defined. Additional diagram layers will be appended as requested. The completed diagram will be displayed in a RockPlot2D tab in the Options window.

7. You can adjust any of the program settings via the Options tab to the left, and then click the Continue button again to regenerate the diagram.
8. View / save / manipulate / print / export the cross section in the RockPlot2D window.
