The Geotechnical Module 2017 is now available to all AutoCAD Civil 3D

subscription orders. This hands-on lab will show you the basis of getting

started with the Geotechnical Module in AutoCAD Civil 3D 17. Within

minutes of starting the class you will see how to access and import

subsurface geology data in AutoCAD Civil 3D. The class will go on to show

you how quickly you can visualize boreholes in context of your site, create

multiple strata surfaces and even generate geotechnical profile views

containing borehole log strips all in a few minutes. This is work which would

normally take many hours. By the end of the session you will have a greater

understanding of how the Geotechnical Module works, allowing you to

incorporate geotechnical subsurface data in your infrastructure designs,

using AutoCAD Civil 3D.

Class summary


At the end of this class, you will be able to:

Understand the fundamentals of the Geotechnical Module

Create a project and import geotechnical data into AutoCAD

Civil 3D

Create and visualize 3D boreholes and geology strata

surfaces

Create dynamic Geotechnical profile views which display

borehole log strips

What is the Geotechnical Module?


CVS and AGS

Project Management and Import


Plan and Model

Creating and Managing Boreholes


Creating and Managing Sub Strata Surfaces


Borehole Logs Strips

Production of Geotechnical Profiles Views


Geotechnical Hatch and Style Management


Autodesk Subscription Website


It's a good starting point

Surfaces may have to be manipulated Lens

Faults

Does not support additional down hole data Ground water

In situ and Lab tests results

Contaminants

etc.

Only works on the local machine

What are its limitations?


Web Mapping Services

Photos

Aerial Photography

Local Knowledge

Geophysics

Down hole information

Use as many sources of data as you can


Not a replacement for geotechnical knowledge

and experience
