  1. When modeling contamination as a solid block model, there is an interpolation modeling option called "directional". Here you can specify the direction as well as bias strength. If I'm modeling contaminants that I know flow in one direction for a period of time, but then change direction, is there any way to model both of these influences in Rockworks? Thanks, -Andy
  2. Hello Brian, I tried the settings that you've used for your example, and the only thing that I see that is different is that I'm replacing the top surface with my DEM so that all the ground topology is modeled correctly. Rockworks is still not trimming the 1st, 2nd, and 3rd strata out of the canyon where it should be cutting it out. Any other ideas from people?
  3. I am building a relatively simple stratigraphy model and I have been using a ground surface grid with the "Constrain Surface Grid Model". When I build the stratigraphy model the top of my upper most stratigraphic layer is correctly being trimmed out (probably because I have it set to "replace Top Surface with Ground Surface" turned on), but the "base" for this upper strat layer is not being trimmed out. Therefore, in a canyon within the project area I am getting a flat surface that goes through it from the "base" polygon. How dose one ensure that the base polygons are being clipped out as well as any underlaying stratigraphic layers? (See attached picture) I've tried going through all of the options about hiding thin zones and creating pinchouts, but none of these seem to have an effect on the base of my first unit. Thanks, -Andy P.S. In the image the area outlined with red is the flat base of the first stratigraphic unit. This should not be showing and it should be a canyon showing below it.
  4. I have measured top-of-water (head) data for a set of monitoring wells and I'm curious where this information would be entered into Rockworks. The Water Levels tab of the BHM seems to be for the thickness of the aquifer, but if you have data that represents head heights, can this be indicated on a time-based tab similar to T-data or the Water Levels tab? If it is something one would enter into the T-Data tab, is there a way to create new T-data tables so that this data is not mixed up with my chemical sampling data? Thanks, -Andy
  5. Block model of Stratigraphy

    I believe I found a solution to my problem using method 1 above. I've built the stratigraphy model which uses surfaces to represent the stratigraphy. I then built a block model of the lithology of my project area. I then "extract" each stratigraphic unit by rebuilding a block model using the Top/Bottom bounding layers from the stratigraphy model computed previously. Once each stratigraphic unit has a block model built, I can use the tool: Utilities: Solid: Filters: Replacement Filters and re-assign all of the blocks to the proper stratigraphic unit number. I haven't completed this completely yet, but I assume that it will work from the one unit that I've done so far. If you change the coloring table to the Stratigraphy table it seems to be visually working at least (which is all that I need this for anyway). -Andy
  6. Block model of Stratigraphy

    Is there a way to create a block model (the same techniques used for the Lithology models), for my stratigraphy data? I've got two possible solutions I've thought of, but perhaps there is a better way: Option 1) Create the stratigraphy surfaces using the normal stratigraphy model, and then rebuild block models using the top/bottom surfaces for each stratigraphic layer to confine the lithology block model. Then I would need to find a way to re-assign those blocks to the stratigraphic unit they're representing. Option 2) Enter my stratigraphy tops into the Lithology tab of the Borehole Manager in a new database - then create a block model using the lithology modeling tools (although it will be stratigraphy tops instead). I want to do a stratigraphy block model so I can utilize the animation cut-down options. As far as I know, these can't be done with the default stratigraphy surface models. Thanks! -Andy
  7. 3d animation cut-down

    I guess this may not be possible. Perhaps I can export each individual layer as a shapefile object and render it in ArcScene with fades between layers. One other question: Is there any form of keyframe animation built into Rockworks for controlling different types of animations and layer vizibility?

    Accidental duplicate post. Please remove.
  9. 3d animation cut-down

    I've had a coworker request an animation that mimics the "cut down" style of animation that RockWorks automatically generates for us. However, instead of cutting down equally with a plane, he would like each layer of rock in a Lithology block model to be removed one at a time (and perhaps fading out between each layer). Is there a way to do this in Rockworks without manually doing the animation by hand with G-Values and turning each layer on and off? I've thought that this would achieve the look we're after but it would be quite a bit of work to do it. Have all the G-Values for lithology be assigned from the bottom up (or top down), and after generating the lithology block model turn a lithology layer off by filtering it out, save a graphic of the block model, then repeat for the next layer down. You could then take each of these frames and put them in video software with a fade between frames. Thanks for any help you can think of, -Andy

  11. Hi Tom and Alison, Thank you for the further directions on how to best export data to shapefiles. This will be great to read through. I tried doing the instructions outlined for Borehole data and I'm running into an error. After I run the export command for a shapefile RockWorks throws an error that says: "exception message: Could not convert variant of type (Null) into type (Double)." Any ideas on how to resolve this error? Thanks, -Andy
  12. Hello, When you're exporting a shapefile of a 3d striplog model of, let's say, I-data, I get a value field. It has a number in there that doesn't correspond to the value of what the i-data sample should be. Is this a coded value that's a combination of numbers that can be broken out to retrieve what the sample data was? I've tried looking through the Access database of my project folder for that same number and nothing comes up. Please see the screenshot for an example of what I'm referring to. -Andy
  13. Is there a way to process a model for one large extent, but only view a smaller extent within the model in order to help increase viewing performance and responsiveness? For instance, I have an area that has a few boreholes that are further away from the main project area. I wanted to use those to help control the lithology and stratigraphy of the model, but I only want to view and do visualization work with the main concentrated set of boreholes. Am I able to calculate the lithology model using the outside boreholes, but limit my model to only show the secondary view extent? Also, I didn't want to start a new topic for this, but are there any plans or future for utilizing multicore/processors in Rockworks? Thanks, -Andy
  14. Hello, I'm trying to use some control point boreholes to model a specific location of a pinchout point on a cross section, but I keep having a stratigraphic unit pop up which should not be there. I've attached a few files that will help show what my issue is. The stratigraphic unit that should not be showing up is the cyan (Unit 3) color that's highlighted in red. I need this unit to pinch out where borehole "CP1" is located. This is my artificial borehole which is acting as a control point to limit the unit from showing up to the left of it. I've been modeling the pinch out points as using the same depth from top for the units and I've included the tables for the three boreholes in tables below. T = Top B = Base F = Formation MW44 T B F 0 2 1 2 2 2 2 2 3 2 11 4 11 29 5 29 40 6 40 68 7 68 99 8 99 107.5 9 CP1 T B F 0 2 1 2 2 2 2 2 3 2 * 4 * = entry left blank to show this is not the bottom of formation MW41 T B F 0 4.5 1 4.5 4.5 2 4.5 11 3 11 30.5 4 30.5 34 5 Does anyone have any idea what is making the cyan unit show up in MW44? The stratigraphic log that's overlaid on the cross section clearly does not show the unit in it. Nor does MW45. Thanks for the help, -Andy
  15. Mira, Have you considered exporting it as a DXF 3d file and using a free DXF viewer for your clients? I don't have any experience with this, yet, but I will most likely be investigating it as an option myself over the upcoming weeks. If you do find something that works for you, I would be interested in hearing about it in your post. -Andy
