(040) Bug Fix (11/29/10/MIW): Importing text based grids (ESRI, ZMAP, ASCII, etc.) no longer fails when the Windows number formatting is something other than dot for the decimal separator and comma for the thousands separator.

 

(039) New Feature (11/24/10/JPR): Four new conversions have been added to the Utilities / Solid / Convert / Solid -> Grid program.  These conversions are used to create grids in which the z-value represents the highest elevation for the highest g-value, the lowest elevation for the highest g-value, and so on.

 

(038) Bug Fix (11/23/10/MIW): Plotting control points wthin the Utilities / Solid / Model program no longer produces and error.

 

(037) New Feature (11/23/10/JCJ):  The sorting of the boreholes is now changeable.  The sort order is now defined within a new menu titled "Change Sort of Boreholes" within the View menu.

(036) Improvement (11/23/10/JCJ):  The lack of a criteria will no longer close the Filter dialog.

(035) Improvement (11/23/10/JCJ):  If the raster symbol for a borehole is undefined or it's index numbe is out of range, the symbol will be set to 1.

(034) Improvement (11/23/10/JCJ):  If the vector symbol for a borehole is undefined, the symbol will be set to number 14 at a color of black.

 

(033) New Feature (11/19/10/MIW): A ZMAP (Petra, Geographix/Landmark/Halliburton, etc.) grid importer has been added to the grid import program.

 

 

(032) Improvement (11/18/10/MIW): Creating a striplog with a total depth less than or equal to zero not generates a helpful error message.

 

 

(031) New Feature (11/19/10/MIW): A ZMAP (Petra, Geographix/Landmark/Halliburton, etc.) grid importer has been added to the grid import program.

 

 

(030) New Feature (11/15/10/JPR): A new program titled "Isopach (3D)" has been added to the Borehole Manager / Lithology menu.

This program creates an isopach model based on the uppermost and lowermost occurences of the designated lithologies (regardless of what lies in-between these two imaginary surfaces).

Note: This object displayed by this program shows all voxels from the uppermost occurence of the designated lithology to the lowermost occurence.  This means that other lithologies may exist between these two surfaces.

 

(029) New Feature (11/15/10/JPR): A new program titled "Isopach (2D)" has been added to the Borehole Manager / Lithology menu.

 

 

This program creates an isopach model based on the uppermost and lowermost occurences of the designated lithologies (regardless of what lies in-between these two imaginary surfaces).

 

 

Note: This map that is displayed by this program and the associated grid model is based on all voxels from the uppermost occurence of the designated lithology to the lowermost occurence.  This means that other lithologies may exist between these two surfaces.

 

 

(028) New Feature (11/15/10/JPR): A new program titled "Subface" has been added to the Borehole Manager / Lithology menu.

 

 

This program is identical to the new Lithology / Superface program (see item #23 below) except that it generates a surface model (grid) whereby the elevations represent the base of the lowest occurences of the selected lithology.

 

 

(027) New Feature (11/15/10/JPR): A new program titled "Superface" has been added to the Borehole Manager / Lithology menu.

 

 

This program is used to create a surface model (grid) whereby the elevations represent the top of the shallowest occurence of the selected lithology.  A "null" value (-1.0e27) is assigned to any grid nodes that do not have a corresponding lithology within the original lithology block model.

 

 

Here's an example using a "worst-case" polygon-clipped lithology model in which we are interested in creating a surface model at the top of the sand lithology as shown by the yellow voxels.

 

 

 

(026) New Feature (11/14/10/JPR): A new program titled "Block Model Grade Statistics By Level" has been added to the Utilities / Volumetrics menu.

 


This program is designed for users who are evaluating (i.e. mine planning) the ore within a pit shell on a level-by-level basis.

To use this program;

 

- Set all the node values outside the pit shell to a null value by using the Utilities / Solid / Filter / One Bounding Grids program.

 

 

- Create an ATD file that lists the g-value intervals of interest. 

 

 

- Select the new Utilities / Volumetrics / Block Model Grade Statistics By Level program.

 

- Specify the following parameters;

  • Solid Model File:  This is the name of the block model to be evaluated.

  • Cutoff Levels: 

    • Single:  If you're only interested in a single range, select this option to avoid the hassle of creating an ATD file (see next item).

    • Multiple:  If you're interested in the volumetrics for multiple ranges of g-values, create an ATD file with the interval information (see above) and then specify the appropriate columns within the sub-items for this option.

  • Items To Be Computed For Each Level:  A variety of statistical items may be computed by this program.

  • Unit Annotation:  These designations will be listed, in parentheses, within the report that is generated by this program.

  • Intervals:  The report can either list the statistics within each layer of the model, or the user may specify an upper starting elevation and the interval spacing.

- Select the Process button and a report such as that listed below will appear;

 

Note:

  • The minimum, maximum, and average values are not totaled.

  • The minimum, maximum, and average values are not computed for the undefined nodes.

  • The undefined mass is not computed.

 

(025) Bug Fix (11/12/10/MIW): RockWorks drawings (RK6) with a vertical exaggeration that caused part of the plot to be drawn outside the rectangle boundaries were being incorrectly clipped when printed.

 

 

(024) Bug Fix (11/12/10/MIW): In RockPlot2D, clicking over an item that isn't visible (layer disabled) was still selecting that item and preventing visible items from being selected.

 

 

(023) Improvement (10/27/10/JCJ): The RCL "DEFINE:" command will now accept either a track name or it's relative ID number.  The previous version would only accept the track name.

 

(022) Bug Fix (10/21/10/MIW): Polygons exported from RockPlot2D to ESRI Shape file format weren't correctly terminated.

 

(021) Bug Fix (10/20/10/MIW): RockPlot 2D + 3D files can now be saved to a non-project folder without causing an "Invalid File Name" error.

(020) Bug Fix (10/19/10/MIW): I and P Text labels were being shifted down in 2D boreholes even though borders were not enabled.

 

(019) Improvement (10/19/10/MIW): Added an option to set voxels outside of a model to null when resampling to a model with larger dimensions.

 

(018) Bug Fix (10/19/10/MIW): Using a continuous white to black color scheme no longer causes a Range Check Error.

(017) Improvement (10/18/10/JPR):  The Utilities / Volumetrics / Extract Solid program will now show the best stripping ratio and the associated minimum pit elevation in the event that an optimum pit is not achievable given the designated maximum stripping ratio.

(016) Improvement (10/18/10/JPR):  The Utilities / Volumetrics / Extract Solid program will now show the best stripping ratio and the associated minimum pit elevation in the event that an optimum pit is not achievable given the designated maximum stripping ratio.

Note:  Stripping ratio iteration termination (i.e. when the program "gives up") is based on computations before adding benches.  The final stripping ratio, as shown in the report that is generated by the program will be higher, depending upon the bench height.

(015) Improvement (10/18/10/JPR):  The Utilities / Volumetrics / Extract Solid program is now significantly faster when handling large models and somewhat slower when processing small models.

(014) Improvement (10/18/10/JPR):  The Utilities / Volumetrics / Extract Solid program will no longer laterally extend the pit outside of the region defined by the ground surface grid.  This modification is based on the logic that a pit slope can't be created unless the program "knows" where the edge of the pit will be (i.e. the elevation of the projected slope top must be known).

(013) Improvement (10/18/10/JPR):  The "Depth Increment" parameter has been removed from the Optimize section within the  Utilities / Volumetrics / Extract Solid program menu.  Instead, the program now automatically decrements the maximum depth with each successive optimization pass by moving upwards by one layer of voxels.

(012) Bug Fix (10/18/10/JPR):  The Utilities / Volumetrics / Extract Solid program no longer creates sporadic vertical faces within the final excavation pit.  This was a fairly rare problem but nevertheless, a "show-stopper".

(011) Bug Fix (10/14/10/MIW):  P-Text in 2D Borehole Logs is no longer moved down when its border was not being plotted.

(010) Bug Fix (10/11/10/JCJ):  Imports of Excel files into RockWorks when the database is MS SQLServer will import correctly when the data uses non-USA formats.  RockWork was converting the floating point data to a string and back again with conversion errors.

(009) Improvement (10/06/10/MIW):  Added a Decimal Places option to the Map|Adjust Coordinates|Longitude/Latitude -> Easting/Northing menu.

(008) Removal (10/06/10/MIW):  Removed the Include Date Ranges option from the Aquifer sub menu for 2D Striplog design.

(007) Bug Fix (10/06/10/MIW):  The Solid Model Polygon Filter option in the Solid Algorithms dialog now works correctly.

(006) New Feature (10/02/10/JPR):  The Borehole Manager / Lithology / Model program now includes a filter that will limit the input based on a g-value range.  In other words, this is a method for excluding certain lithologies from being considered during the modeling process.

The following scenario illustrates the usefulness of this capability;  Consider some steeply dipping lithologies capped by a thick layer of alluvium.  If we attempt to use the "Tilted Modeling" capability, the alluvium will be tilted as well as the other lithologies.  On the other hand, if we assign a unique value to the alluvium and filter it out (via this new option), the projected/tilted lithologies will not include the alluvium.

(005) New Feature (10/02/10/JPR):  The Borehole Manager / 2D-Striplog menu now includes new options that determine what happens to I-data and p-Data intervals that have no thickness (i.e. Top-Depth = Bottom-Depth).  In previous RockWorks versions these intervals were automatically discarded.  In reality, however, lab results sometimes list interval-based data only as a single depth.  Typically, this is remedied by saving the information as P-data, but occasionally, projects involve data sets in which some of the lab results are listed as zero-thickness while others span an interval.

To discard zero-thickness I-data and T-data, check the "Omit" option.

To display zero-thickness I-data and T-Data, check the "Expand" option and enter the thickness that zero-thickness data should be changed to.  The program will center the interval at the original depth (i.e. the top of the interval is equal to the original top minus half of the new thickness height).

(004) New Feature (10/01/10/JPR):  The Borehole Manager / Lithology / Model program now includes an option for defining the "group title" that will be displayed within the RockPlot/3D diagram.  This title is also used as a prefix for the model volumetrics group.  The previous version was "hardwired" to title all lithology models as "Lithology Model" and all volumetric groups as "Lithology Volumetrics", thereby requiring manual editing of the RockPlot3D "data tree".  This new capability is especially useful when combining groups of models into a single RockPlot3D diagram.

(003) Bug Fix (10/01/10/MIW):  Location maps that are embedded within profiles are no longer stretched incorrectly if the x and y coordinate ranges are not equal.

(002) Bug Fix (10/01/10/MIW):  Compiling a single 2D strip log from an RCL batch file no longer causes an invalid index error.

(001) Bug Fix (10/01/10/JPR):  The Utilities / Grafix / 3D-Utilities / Cage program now recognized the dimensioning method (i.e. Project Dimensions, Automatic, and Manual).  The previous version always used the "Manual" setting.
