  1. 3D borehole tubes not appearing circular

    One other question related the OpenGL precision limitation: does this affect interpolation or rendering of 3D solid models as well?
  2. 3D borehole tubes not appearing circular

    Thanks for the prompt response, Alison. Yes, my project is only about 55' by 20' and it is currently expressed in StatePlane Coordinates (thus ranging in the millions in terms of absolute values). So it does appear to be the same problem reported in January 2013. Setting up a dummy coordinate system for RW is not particularly desirable in my case since it would leave the project incompatible with other import/export datasets currently in use (such as CAD drawing overlays or GIS features). Starting from scratch, altering all the data, and rerunning all the 3D plots and exports would also take a significant amount of time. This is obviously something I will need to consider the next time I need to run a similarly scaled project. Have any programming solutions to the OpenGL limitation been found in the past year? Or is RW simply not able to render these types of graphics for small scale projects set in typical standard coordinate systems? All my models are pretty large files (each one is ~150 MB zipped). Please let me know if it would it be all right for me to send you only the RW project .mdb since we are just considering borehole locations right now. thanks again, Lara
  3. Hi I am generating plan views from above of my 3D solid model in RW15 and need to show borehole locations. I don't know why I am unable to get boreholes generated as tubes to appear as actual symmetrical circular tubes. Despite trying many different settings, they are generating as asymmetrical blocky shapes. Please see attached plan views at a 300% zoom level showing the inadequate representation of the boreholes generated at both a 5% and 1% of project size setting. I get the same type of results generating boreholes as tubes in terms of map units. I have also tried boreholes as polylines, which do not appear at all in 3D plan views, and exporting a 2D borehole map to a 3D file, which unacceptably renders the circular 2D borehole markers as irregularly sized jagged shapes in 3D plan view. Any ideas on how to get an acceptable depiction of my borehole locations in 3D plan views from above? Thank you, Lara
  4. automate volume calcuations

    Thanks for this prompt response, Alison. I'd like to check out the documentation for the Block Model Grade Statistics By Level program. I'm still running RW15 so I sent you an email. thanks! Lara
  5. automate volume calcuations

    Hi I am interested in generating a "function" for a 3D solid model that would allow me to evaluate relative volumes of plume vs. unimpacted soil that would be removed given increasing excavation depth scenarios. Two approaches have come to mind so far: 1. Applying a grid filter to the solid model to cut it off at various depths and then extracting stats from the cutoff models, 2. Extracting stats for each 2D planar slice of the model and then summing stats from the appropriate slices for various cutoff depths. I've also looked briefly at "Volumetrics/Extract solids" and am not sure how to employ it at various cutoff depths. Both of these approaches seem to be very labor intensive in that they require manually iterating each depth level - is there any way get at the information I'm looking for more efficiently and quickly? If it comes down to RCL programming, do you have any tips or advice on whether someone has already written a script like this, which approach would be best from a computing perspective (integrating 2D slices or filtering 3D models), or even just how best to get started? thanks, Lara
  6. Hi Is there any way in RW15 to project (flatten, condense) a 3D solid model onto its 2D xy plane in order to identify a planar contour representing it's maximum xy extents in the 2D plane? thanks, Lara
  7. OK thanks, Tom, for this workaround idea. Glad to hear this limitation is eliminated in 16.
  8. Thanks, Molly. That confirms why I have been avoiding the replacement filter and trying to work instead with overlays of the two separate models. Unfortunately using 2D in RW15 as an alternative for the cross sections requires workarounds involving dummy data (my lithology backfill model only contains one g-value) - please see Tom's response to this recent post of mine: https://www.rockware.com/forum/index.php?showtopic=2251 I do appreciate you digging around some more on this to find out if there are any alternatives we haven't yet considered. I'm still not exactly clear on why RW15 3D slices are replacing data nodes with nulls at the filtered edges to create gaps at my contact, particularly when these edge nodes appear OK from the plan view. thanks, Lara
  9. Sorry for the multiple replies here. I should probably add that the p-data host model employs a cold-to-hot color ramp while the lithology models uses the lithology table. (The pictures I uploaded were only tests of the Polygon Clip and Range filter processes I did using simplified test models with only 1 g-value each to demonstrate the gap issue). thanks, Lara
  10. Also, my p-data host model contains null values I need to preserve outside the interior clip excavation area to be filled by the donor lithology model.
  11. Thanks, Molly. In my case the interior clipped host model is a p-data model and the fill donor model is a lithology model. Both models have the g-values in the same numeric range representing different things with different legends. Will RW track the differently sourced g-values in the combined model or do I need to do some g-value manipulation in advance? Lara
  12. Here are a plan view and an East view with a N-S slice showing the gaps.
  13. Hi, I have a rectangular polygon that is not oriented normal to my coordinate system (i.e. its sides intersect model nodes diagonally). The polygon represents a backfilled excavation area that I am attempting to model. I have removed the polygon excavation volume from a larger site model using Solid / Filter / Polygon Clip, replacing interior with null. I have also generated a model of the backfilled excavation volume by first using Solid / Filter / Polygon Clip to replace the interior of the same polygon with a single unique g-value and then using Solid / Filter / Ranger Filter to replace all other non-unique values (the exterior) to null. I have I appended these two models in 3D in RW15 and they appear to be seamless from a plan view. However, when I view a "Compass View" cross section of the combined appended models in 3D by applying vertical slices of the same position to both models simultaneously, I see gaps running between the two models. Both models are "All Voxels" diagram types and have the same dimensions/resolution. I would like to see these models abut in 3D section view slices since they represent the walls of a backfilled pit in contact with the fill material. Any ideas on why I see gaps at the contact between the two models in 3D and how I might fix this? thanks, Lara
  14. clip model extents

    Hi, I have a solid model whose extents I would like to clip down without resampling. I want to generate a "zoomed-in" subset of the original solid model without any altering any node values. Running Solid / Filter / Polygon Clip results in no change to the model extent; it just replaces areas outside my subset with null values. (A large empty space around my subset becomes a problem when I want to run animation reveals that portray just the subset). The user in this 2008 post was trying to do the same thing and came up with the idea of exporting the model, manually altering the extents defined in the header of the text file, and reimporting: https://www.rockware.com/forum/index.php?showtopic=879 Is there a better way to do this in now in RW15? And if not, can you verify whether or not the export/import method described in the 2008 thread yields a true subset of a solid model? thanks, Lara
  15. Hi I am interested in generating cross sections or profiles of a solid lithology model containing only 1 g-value (representing a backfilled excavation pit). My end goal is to take these excavation area lithology cross sections and append them to my larger p-data concentration cross sections so that the excavation/backfilled area within the combined section is appropriately represented. I can view my single g-value lithology model all right in 3D but when I try to run a profile or cross section on it, I get an error telling me "All of the g-values within the solid model are equal to 4.0", and the profile won't plot. How do I depict my single g-value backfilled excavation pit in 2D cross sections and profiles? thanks, Lara
