  1. Since we resolved this through email, I have posted a summary of the problem and solution below. First, attached is a view of the original contour map. You can see that the contour lines and the color fill do not quite match up, and the contours lines are very blocky. The problem seems to be caused by some very flat areas in the grid that correspond also to the contour line elevations. This can happen when a grid is created based on digitized contour maps. Attached is a view the modeled values and original control points. You can see the flat area surrounding the original control points assigned an elevation of 12.0. The solution was to turn on the "densify" option during interpolation, which adds additional control points in-between the original linear control points. This gets rid of the flat areas and creates a better model.
  2. Hi Mathieu, I don't know why you would have this size limitation. If you would like to send the image to tech@rockware.com, we can post it here along with a response. Best Regards, Alison
  3. The contours in your map are based on the locations of cell in the RwGrd file, and not the boreholes themselves. So, you will need to make adjustments to either the cell dimensions or your gridding settings. 1. As far as the gridding settings go, if you have the "Smoothing" option turned on under the Special Options tab, it may help to also check on the "High Fidelity" option as well. You could also experiment with the settings in the Smoothing tab. If you have increased the Filter Size or Iterations values to something greater than 1, you should try changing these back to the default values of 1. 2. If this does not help, then it may help to decrease the size of the cells. This is done through the Dimensions tab at the top of the RockWorks program window. I hope this helps. If you continue to have problems with this, we may need to take a look at your data to make further suggestions.
  4. Mathieu, My testing using RockWorks2022 shows that the grid NULL values are taken into account during resampling, so the extent of the resampled grid generally matches the extent of the original grid. What version of RockWorks are you using? Regardless, the Grid | Filter | Polygon Clip tool could be used to assign null values to cells in the resampled grid that fall outside of the polygon you used to clip your original model. Best Regards, Alison
  5. RockWorks does not include an option to create grids based off of more than one source file. You will need to compile all of the data into a single RwDat file or a Txt/CSV file (note that the XYZ -> Grid program allows you to interpolate based on a DataSheet (RwDat file) OR an ASCII file. The one exception to this is that the Stratigraphy Modeling program allows you to use "Supplemental Points" when creating a model. This requires that you compile the additional data into a single RwDat file that has a specific format. The program would then use the data stored in the Stratigraphy Table of the database along with the RwDat file during the generation of grids that make up the Stratigraphy Model. We are always working to improve the program and would like to get some more information about the types of data you can combine in Petrel during grid interpolation. You have mentioned sheets, lines and existing grids. If you would like to contact us with some additional information about how this is done, we would be happy to log this in our "wishlist" database and consider it for a future build of RockWorks. You can contact us at tech@rockware.com.
  6. Based on the error messages, it also seems like you may have a unit called "undefined" in the Stratigraphy Types Table. Deleting that from the Stratigraphy Types table may resolve the problem.
  7. In RockWorks, Lithologic cross-sections are created from solid models (as displayed in your second figure). There are options to both "tilt" and "warp" solid models during creation under the Model\Special Options tab. The tilt option assumes a constant dip and direction for bedding. The warp option allows you to specify a structural surface as an RwGrd file, and then warps the lithology model along that surface. Please take a look at this and let us know if you have questions. Best Regards, Alison

    Hi Craig, Here is a link to our client upload site: https://www.rockware.com/upload-for-rockware/ You may need to zip up the DXF file to get it to go through. Best Regards, Alison

    Craig, We'd be happy to take a look. Please send the DXF file over to tech@rockware.com along with information about the coordinate system you using, units, etc. Thanks, Alison

    Also, here is a KMZ file that I find really handy showing all of the State Plane zones. I often plot some Lat/Longs from my project along with this just to confirm that I'm using the correct zone.USA_State_Plane_Zones_NAD83.kml

    Are you seeing this shift when you export to Google Earth? If so, then yes, I think I would try reassigning the coordinate system in your project through the Coordinates tab. Unless you are working with some coordinates in your project that are in different units or a different coordinate system, I don't think you should need to re-scan your data to re-establish project dimensions.
  12. Vincent, Unfortunately, I am not able to reproduce this problem using our Sample dataset. Could you please contact tech@rockware.com with your menu settings? This might help us diagnose what the problem is. To create an RwMenu file, go to File|Export|I-Text and then click the Settings button in the upper right corner of the menu. Use the Save Current Menu Settings button to save the file. Best Regards, Alison

    Craig, The Spatial Filter tools at the top of the window will exclude data from the mapping calculations, but will not limit the extents of the grid. If you have a polygon that defines the extents of the xyz data, then you should turn on the Polygon clipping options during grid creation. Here, you can have the program create a polygon (using the Automatic settings), or reference a polygon file or table. You can set the grid cells outside of the polygon to null, so the contour lines in the map will not extent outside of the dataset area.
  14. We recommend that users take a look at this new forum posting before following the instructions above: It appears that the installation of a patch posted on the RockWare website (related to a known bug in RockPack) may also fix this issue.
  15. Users have reported a DLL error running the Safety Factor Calculations in RockPack III on a Windows 10 64-bit computer: Class not registered. You need the following file to be installed on your machine. MSSTDFMT.DLL. This is a DLL which is apparently not installed with newer versions of Windows, and it is required by RockPack III. We have found that one easy solution to this problem is to install the RockPackIII Plane2Beta Patch, which is described on the RockPackIII support page: https://www.rockware.com/product/rockpack-iii/#tab-in8sync_rockware_support The patch was originally designed to resolves some known errors in the PLANE failure calculations when metric units are used. We have found that it also seems to install this missing DLL. If you run into this problem and the installation of the patch does not resolve this, please contact tech@rockware.com.
