The surfaces can also be created with the Autodesk Civil 3D Geotechnical Module This video shows how you can create a Solid Geology Model in AutoCAD Civil 3D by taking two surfaces and extruding them in a certain way. The video goes through the process twice on different geology layers so you can see how to apply it to models with more than one Geology layer. The video finishes by showing how a AutoCAD section plane with addition Jog points can be used to create impressive 3D fence diagrams from the 3D Geology Model. This technique can be used for exporting solid //www.youtube.com/watch?v=WWFZK4IY2g8 Show more
