  1. Peter, The Triangulation Surface, as well as the Gridding tools in RockWorks are really designed to work with XY "Z" data, or XY "Rho" data in your case. You would need to somehow convert your XYZ data to "XY" data where X is distance along the profile and Y is elevation. A better solution might be to create a solid model of your data through the Solid | Create | XYZG to Solid tool. This will create an RwMod file. You can then use the Solid | Profile tool to cut a profile through the RwMod file. Please take a look at these tools and let me know if you have any questions or problems. Best Regards, Alison
  2. Josh, Yes, you could do the same thing with a top contacts (leave them blank if the upper portion of the unit has been eroded away). Also, you may want to look into use the "Dip" gridding algorithm, which would allow you to specify a bedding orientation at contacts where this is known. You would need to populate the Dip and Dip Direction fields in the Stratigraphy Table in the Borehole Manager, which are hidden by default. Here are some steps to use to show these in the interface: 1. In the Stratigraphy table, click the Tab Manager button. The Tab Manager window should open up. 2. Make sure that Stratigraphy is selected and click "Edit Fields". 3. Click on the Top and Base Dip Direction and Dip Angle fields, and click OK (and then OK to close the Tab Manager). If you have a constant Dip Direction (which 90 degrees to Strike) and Dip Angle for all of the units in the model, I would populate these fields for all of the populated contacts. You should leave non-intersected contacts at the top and base of each borehole blank, without a depth or orientation information. When creating the Stratigraphy model, you should use the "Dip" algorithm, rather than Kriging or Inverse Distance. You might need to experiment with limiting the number of points used during the interpolation. The more points you use, the smoother the surfaces. Please feel free to send us your data if you are having a hard time with this project. We'd be happy to take a look and provide additional advice! You can send a backup of your project to tech@rockware.com. Best Regards, Alison
  3. Peter, thanks for the clarification! You can extract elevations from the contour line vertices into the Datasheet using the File | Import | SHP menu. Once you've created an .RwDat file that contains the XYZ elevations, you can created a grid based on this data through the Grid | Create | XYZ to Grid program. The grid can be displayed as a 2D contour/color map, or as a 3D surface. Some things to mention: 1. You'll want to make sure that the units and coordinate system assigned to the X, Y and Z columns in the RwDat file are accurate. 2. You should be sure that the Grid Dimensions specified in the Dimensions tab (towards the top of the RockWorks window) match the data you've imported. I hope this helps. If you run into any problems, it would help if we could take a look at your shapefile. You can send this to tech@rockware.com. Best Regards, Alison
  4. The Reportwork program that comes with RockWorks is designed to do this. If you save your diagrams as RW2D files, you can place them in the Reportworks paper space along with title blocks, images, rectangles, lines, etc.
  5. Thanks for these details. The scattergrams in RockWorks are really not designed to reverse the Y axis like this. My only suggestion would be to multiply your depths by -1. If you plot negative depths in the scattergram, the data will be inverted about the X axis.
  6. Ali, What type of graph are you trying to create? If you could provide some details about the menu item you are using and the type of data you are working with, it will help us determine how you should proceed. Best Regards, Alison
  7. Peter, RockPlot3D does not have a 3D Shapefile import, but it does include a 3D DXF import. If you are able to convert your shapefile to a DXF file, this is probably the best way for you to proceed. If this is not an option, please go ahead and send your shapefile to tech@rockware.com, and we'll see if we can come up with a workflow for you. Best Regards, Alison
  8. Tim, For boreholes that don't fully intersect a unit, I would recommend that you leave the depth of the lowest unit (for example, the base of Unit "B") blank in the database table. As long as you have that contact defined in deeper surrounding boreholes, the program should use the surrounding contacts during grid interpolation. Here is an example of how this looks in a shallower borehole in our Sample project. There are some model settings that you may have adjusted that could affect how this works (under the Strat Rules tab in the various Stratigraphy modeling/diagram windows). Also, if the base of Unit B has a highly variable elevation, then you could run into problems where the program plots the contact above the base of the borehole. In this case, we usually recommend that you add a contact point below the base of the borehole (this is pretty rare). If you continue to run into problems, we would be happy to take a look at your project. You can back up your project or database through the File menu in the Borehole Manager, and send us the ZIP file created during the backup process. Please send it to tech@rockware.com. Best Regards, Alison
  9. Dear Jaeishik Chung, This seems to be a permissions issue. Is a report generated when this error occurs? If so, it would be helpful if you could send this to tech@rockware.com. I do not believe that we've seen this error before. Best Regards, Alison
  10. Hi Mette Lise, Yes, this is possible using the "Regular" mesh type with the "Custom" Divisions option selected: Please let me know if you have any questions about this. Best Regards, Alison
  11. 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.
  12. 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
  13. 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.
  14. 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
  15. 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.
