The techniques used to model geology on sites often do not work well for linear routes where the positions of the boreholes are not conducive to generating usable triangulated surfaces. This class will discuss the techniques to employ when working with boreholes positioned along a length of proposed road or rail network. It will also examine the workflow of using geotechnical profile views to sketch geology interpretation, which can then be incorporated back into the strata surfaces, letting the user visualize and model the subsurface geology. The class will step through the process of creating geotechnical profiles, and sketching and updating profiles from which 3D feature lines are created; these are then incorporated as breaklines back into the AutoCAD Civil 3D surfaces, producing usable triangulated surfaces, enabling the geology subsurface to be modeled and visualized on linear routes.
- Understand the workflow required for modeling geology on linear sites
- Learn how to use static profiles to sketch and interpret geology
- Learn how to extract 3D feature lines from strata profiles
- Learn how to update and manipulate AutoCAD Civil 3D surfaces using the extracted feature lines
Gary Morin originally trained as a civil engineer and has over 30 years of experience working in the production and support of a range of geographic information and CAD software systems. He is now the Technical Director of Keynetix, which he co-founded in 2000 to specialize in geotechnical data management software. He heads up the geotechnical Building Information Modeling (BIM) development, and is responsible for the design and support services for a range of products designed to manage geotechnical data in the BIM process, including the HoleBASE SI Extension, the Geotechnical Module from Autodesk, Inc., and the advance HoleBASE SI Extension for AutoCAD Civil 3D software. In recent years Morin has been at the forefront of geotechnical BIM and how it can change working practices to enable a better understanding and integration of geotechnical data into the wider construction process
