Exporting Lithologic Surfaces to DXF

As RockWorks view the world, lithology materials are not necessarily layered – they can repeat within a single borehole and may be inconsistent in sequence across the project area. As such, RockWorks uses a solid modeling process, rather than surface-modeling, to create lithology models, with the 3D nodes or voxels assigned a material type and represented in the 3D viewer as color-coded blocks.

This presents a challenge, then, for users who wish to view lithologic SURFACES as plan-view contour maps, or in 3D, or exported to CAD.

In RockPlot3D you can access the lithology model’s Options window and filter the display for the desired material type, or range of types. Here is the above model filtered to display the Soil voxels only.

This can be exported to DXF, but note that you’ll be getting all of the blocks representing that material. (Shown here in black and white for contrast purposes.)

If you need a surface rather than blocks, RockWorks also has tools which will fit a surface to the uppermost elevations or the lowermost elevations of a rock type in a lithology model. These are in the Lithology | Superface (Top) and Subface (Base) menus. Here is an example of the same soil lithotype extracted as a surface (upper elevations), and displayed in RockPlot3D and then exported to DXF.

RockWorks “Triangle Map” Illustrates Water Quality in Eastern Virginia Aquifer

Thanks to David Buss at aquaFUSION, Inc. for allowing us to post this map created using RockWorks15 and ArcGIS.

The triangle map (created through the Map -> Multivariate Maps -> Spider Map menu in the RockWorks Utilities and imported into ArcMap as a DXF)  illustrates the relative percentages of Filtered Residue, Fluoride and Sodium in well water as triangles with variable shapes and sizes.  Each triangle “axis” is scaled independently based on the minimum and maximum measured value of that constituent normalized to values ranging from 0 to 100.

The triangle map shows a general increase in constituents in well water in the in the southern portion of the watershed, as illustrated by larger triangles in Northumberland and Lancaster Counties.  A more subtle trend can be seen when comparing triangles located along the groundwater divide (which generally follows the eastern border of Richmond County) to those closer to the rivers.  There appears to be a correlation between proximity to a river and the amount of TDS, Sodium and Fluoride in well water.
