Geology Faults In AutoCAD Civil 3D More information http://www.keynetix.com/civil3d This video was created Using AutoCAD Civil 3D and HoleBASE SI Extension for Civil 3D. The surfaces can also be created with the Autodesk Civil 3D Geotechnical Module This video shows how to take a polyline and convert it into a feature line. It then shows you how to arange these features lines so that they do not interact with each other. Once the feature line has been drapped it is then used as a breakline that simulates a geotechnical wall fault.
