The Orientations from Wireframes tool extracts and blends the local azimuth and plunge from a wireframe (or a set of wireframes) to populate a block model. This can then be used with the Variable Search options in the kriging and IDW forms. While using a structural trend model for this purpose can be a time-consuming process, the wireframe-based approach simplifies and accelerates the workflow.
Depending on your block model, you can specify an attribute that defines your domain. In the Wireframes tab, you can specify one or more wireframes. To define the azimuth and plunge (pitch), you have two options:
Using a Variogram Control File: This allows you to inherit the plunge from the main axis of the variogram.
Manual Visualization: Click on the eye icon to load an ellipsoid into the plane of the wireframe. You can then determine the plunge direction by visual inspection. This plunge direction is projected onto the orientation defined by the wireframe. It also gets projected normal to the wireframe. The advantage here is that, even if one end dips toward the north and the other end dips toward the south, the plunge direction remains consistent. When converted to pitch, it retains the same direction throughout.
In the Options menu, there are two available methods for orientation calculations: Closest Part of Wireframe, which is accurate and faster, making it ideal when using a mid-surface, and Average Orientation, which is suited for cases when working with both the hanging wall and footwall.
For output, you can either create a new file or modify the same input file by adding new attributes.
To visualize the orientation, go to Wireframe > From Strings > Bedding Plane from Points. This tool generates a planar surface for each block. Fill out the input fields and specify the shape (e.g., 4x4). This will create a wireframe for each point. By setting the draw style to Auto, you can achieve a clear understanding of the orientation attributed to your block model.
