In this lecture, we focus on the practical process of creating a 3D mesh from an existing terrain model developed in the previous session. The terrain data, saved and provided as a supporting file, serves as the foundational dataset for mesh generation. This hands-on session demonstrates how to connect the relevant geotechnical database to access necessary lithology and water level data points, a crucial step before initiating the mesh creation workflow.

The workflow involves activating and configuring key data types such as lithology cylinders while excluding others like the water level for clarity. By querying all updated data points within the connected database, the environment is prepared for accurate mesh modeling. This dynamic approach ensures the terrain and subsurface features are correctly integrated into the 3D space.

We then progress to the 3D modeling tab where the user selects the mesh creation function. Here, the lecture highlights selecting all relevant boreholes and interpretation points to form a comprehensive mesh that represents subsurface lithological variations. The use of an interactive selection method via the mouse button streamlines this process, enabling precise definition of data points that contribute to the mesh structure.

The result is a fully generated 3D mesh, visually represented with layers in distinct colors corresponding to different lithological units, consistent with previous color assignments in the level display manager. This visual differentiation aids in interpreting geological formations and supports further geotechnical analyses. To conclude, the lecture covers essential file management practices, including fitting the view for optimal display and saving the updated project file securely to preserve progress.

This session solidifies the connection between theoretical knowledge of stratigraphy and practical digital modeling using industry-standard software tools. By following these steps, learners gain essential skills to visualize and interpret complex geological data in three dimensions, a foundational competency for geotechnical modeling workflows.

This ability empowers geoscientists and engineers to better interpret subsurface conditions and enhances their capability to integrate geotechnical data into practical modeling workflows for infrastructure and environmental projects.

In this lecture, you will learn the essential steps to create cross sections and interpret fence diagrams, crucial tools in geotechnical modeling and structural geology. Starting with the project file from the previous session, the lecture guides you through managing layer visibility to focus on the cross section lines. By precisely controlling which layers are displayed, you gain clarity and can work more efficiently within the software environment.

The process involves accessing the level display panel to activate the cross section lines, followed by systematically turning off all other layers. This deliberate isolation of relevant data ensures that your cross sections are clear and not obscured by unrelated information. The lecture teaches you practical software navigation skills such as right-click actions and using the 'all off' option to streamline your workspace.

Next, you delve into the 3D modeling environment where cross sections are generated. The default settings are mostly retained, except for a few key adjustments: the selection mode is set to 'by offset,' annotation is changed to display names, and the model is programmed to open upon creation. This workflow design helps you produce labeled, understandable cross sections that are easy to reference and manipulate.

The lecture demonstrates selecting various cross section lines and viewing these as 2D models, which reveals detailed structural geology along each section. Viewing these sections individually enables focused analysis on specific parts of the geological model, providing better insight into subsurface structures.

Building upon single cross sections, you learn to create a fence diagram— a powerful visualization that links multiple cross sections in a 3D perspective. This feature offers a comprehensive spatial overview, allowing you to interpret geological formations and their relations more holistically. The practical guidance includes instructions on selecting the list option, choosing previously created cross sections, and navigating the 3D view by orbiting the model to reveal the full fence diagram.

The lecture further encourages exploration by repeating this process with additional cross sections, reinforcing your understanding and skills. You also learn how to optimize fence diagram presentations by adjusting viewpoint settings and display preferences to achieve the clearest and most informative visualizations possible. Finally, the lecture wraps up with file saving instructions to ensure your work is preserved and ready for future use.
