Managing geotechnical data in Civil 3D has been a challenge over the years. Autodesk introduced the Geotechnical modeler for Civil 3D 2022. WIth this free extension you can export subsurface data from gINT or another method and create .csv files that will import directly into Civil 3D. This data will enable you to display your borehole sticks in plan view, on a profile, and even export for 3D use in Infraworks. We will review the workflow of how to manage your data with a local database then import that data into an existing Civil 3D project. Then we will focus on creating stratum surfaces and subsurface profiles from that data. We will also review the sample files and the config file manipulating those to change the styles of our boreholes including hatch patterns at a certain scale. The end result will be a dynamically linked drawing containing geotechnical data completely compatible with your Civil 3D design
