RockWorks 2021.2.9


Recommended Posts

A new version of RockWorks2021 was uploaded to the RockWare website today, with many new features, improvements, and bug fixes. We've been busy!


The RockWorks Revision History has a complete list, by date, of all changes in the program.


New Features

  • Point symbol maps, borehole location maps, stereonet maps now offer raster symbols in addition to the standard RockWorks vector symbols. They can be uniform, column-based, or table-based.
  • Raster symbol capabilities have been added to many other programs as well: 
      3-D | SpherePlot | 2D Spherical – Point
      3-D | SpherePlot | 2D Cylindrical – Points
      Planes | Stereonet
      Stats | Scattergram
      Stats | Ternary
  • Raster symbols are a new graphic type in RockPlot3D
  • Added new table type "Raster Symbol Range" to Map/Models Tables. Data Dictionary version increased to 37. 
  • A new menu option titled "Traverse Defined By ..." has been added to all of the programs that create sections. If the "Interactive Map" setting is selected, these programs behave just like the used to, meaning that the section location is selected via the Section Location tab at the top of the menu. The new "List ..." options provide a way to define the sections based on ASCII text files that contain either a list of Borehole IDs or XY coordinates.
  • Users can now generate vertical scales for profiles and sections using depth below a Datum.
  • Vertical axis annotations for sections and profiles permit different left and right axis settings. For example, one axis might display elevation and the other depth from a datum. You can block copy the settings from one axis to the other
  • Vertical axis annotations for sections and profiles include a new Vertical Offset setting which allows for "fine-tuning" the endpoint label positions.
  • The Lithology | Solid Model | 3D Solid Diagram | Block Diagram | Filter now includes an option to select a given lithology (based on the Lithology Table) and use its G-Value to set the Minimum and Maximum Visible G-Value settings. This eliminates the hassle of switching back to the Lithology Table to look up the G-Value for a unit of interest.
  • A new program titled "Drape Grid" has been added to the ModOps | Grid menu. This program will create a 3D color contour map in which the elevations are based on an “elevation grid” while the colors are based on a different grid (e.g., geochemistry).
  • A new program titled "Multivariate Grid Map" has been added to the ModOps | Grid menu. This program will use two to five grid models to create multivariate pie chart or star burst maps in which the size of an individual slice or petal represents the average cell value from the associated grid within the vicinity of the diagram
  • A new program titled "Grid Math" has been added to the ModOps | Grid | Math sub-menu. It consolidates the previous Grid & Constant, Grid & Grid, Add Multiple Grids, Multiply Multiple Grids, Absolute Grid, and Grid Sieve programs (which have been moved to the Utilities | Misc. | Obsolete menu to provide backward-compatibility with older versions of RockWorks Playlists.)
  • A new program titled "Solid Math" has been added to the ModOps | Solid | Math sub-menu. It consolidates the previous Solid & Constant and Solid & Solid programs (which have been moved to the new Utilities | Misc. | Obsolete menu to provide backward-compatibility with older versions of RockWorks Playlists.)A new program titled "Solid & Grid" has been added to the ModOps | Solid | Math sub-menu. This program is used to perform mathematical operations on a solid model based on corresponding grid values.
  • A new “Coal” tutorial case study project folder has been added to the RockWorks Data folder. This project folder includes a PDF (Coal Evaluation Case Study Using the RockWorks Playlist) that describes the example Playlist which processes a RockWorks datasheet with 583 boreholes in order to identify the areas in which three coal seams meet a variety of criteria including overburden thickness, interburden thickness, BTU, sulfur, and ash.
  • A new program titled “HTML Builder” has been added to the Misc pulldown menu. This program creates an HTML file based on a list of images and image captions. The intended purpose of this program is to provide a means for organizing and concatenating all of the images that are generated by a RockWorks Playlist into a file that can be displayed within a web browser or edited within Microsoft Word to produce a final report.
  • The RW17 Fault Contours to Fault Surface program has been added to RW20 and modified to Import the fault contours to a 3D fault in the Fault table.
  • Added Project_Cmd to be able to set the project in the Playlist or a command script.



  • The Playlist shows which step is being processed. 
  • The RockWorks20 installer includes the Microsoft Visual C++ 
  • The "Loading" menu that appears when an application menu is being loaded now displays a gauge that shows the loading process. A similar gauge is also displayed within the Playlist when an item is being saved.
  • The Geobody program includes options for specifying cutoff volumes in terms of project units (e.g. cubic meters) and displaying a message if none of the geobodies exceeds the threshold.
  • The Borehole Manager | Edit | Adjust Elevations From Grid program provides options for setting the collar elevation to the new ground surface elevation, for offsetting the existing collar elevations based on the ground elevation changes, and for not adjusting the Collar elevations at all. 
  • The maximum Vertical Exaggeration within the 3D diagram Export menu has been changed from 10 to 9999.
  • Items in RockPlot3D can now be offset in the X and Y directions as well as Z.
  • It is now possible to specify directions between -360 and +360 degrees when specifying the offset direction for parallel profiles.
  • The Utilities | Maps | Lineations/Arrows program now includes color options for the endpoint labels.
  • The Datasheet | Filter | Remove Disabled program is now orders of magnitude faster and the screen doesn't incessantly flicker during the process.
  • Imports into the Datasheet automatically assigns the input filename as the Datasheet filename (with .rwDat extension). If this filename already exists in the folder the user will be prompted for a new name.
  • Text, CSV and Excel Datasheet imports allow the setting of datasheet column types and units. These new settings are stored in the ini file and can be set/edited in a Playlist
  • Since the improvement in the Datasheet import of CSV files allowed multiple lines and quotation marks in a field, The Save and Open a datasheet will now also allow these improvements.
  • A number of changes have been made to the ModOps | Grid | Import | Bitmap program, including importing large GeoTIFF images, crop the data to the project dimensions, rescale the image pixels to the project dimensions cell size, accommodate image dimensions in a corresponding World file that are expressed in a different coordinate system.
  • ModOps - Solid | Filters | Tunnel Clipping and Borehole Clipping now accept (and default to) the RockWorks null value.
  • The ModOps | Solid | Edit - As Block Model program is no longer limited to 100 points when defining the vertices of a replacement polyhedron.


Bug Fixes

  • When selecting a profile or section points the user can have an image as a background to assist in selecting the points. (File | Options | Project Image Options) 
  • Draped images in RockPlot3D now clip the image when the image location is larger than the grid it's draped on.
  • The Graphics | 2D Tools | Export | PDF | Single/Multiple program can add to Playlist with the Add to Playlist button.
  • The ModOps | Solid | Extract Grids | Solid -> Total Ore Grid now accommodates solids that have null values.
  • The Delete key now works on blocks of cells in the RockWorks Datasheet.
  • ModOps | Grid | Drape grid, works with Custom Color Tables, honors assigned table name.
  • Borehole Operations | Lithology | Multi-variate Map will now honor the Use Existing Model Option.
  • Datasheet | File | Import | Excel, CSV and Text was freezing or reported a pointer error when defining column types and units.
  • Importing into the datasheet from a text file with no header, no longer takes the first row as a title. The first row will appear as the first row in the Datasheet.
  • Running a command script (RwCmd) from the command line or Windows File Explorer no longer causes RockWorks to load without any docked forms. In addition the command script will now be processed automatically.
  • ModOps | Solid | Logic | Mass Calc: Missing parameter for density conversion has been added.
  • ModOps | Solid | Extract Grids | Solid Layer -> Grid now uses the correct orietation.
  • The color fill contours in Cross Sections and Profiles now honor the faults that are enabled in the Fault table.
  • RockPlot2D no longer exports layers that are inactive to RockPlot3D.
