Using Geotechnical Data in AutoCAD Civil 3D

Gary Morin Keynetix Ltd.

C14020

The class will introduce the new AutoCAD Civil 3D Geotechnical extension to dislay and !odel

su"sur#ace data #or in#rastructure design wor$. This class will show how "orehole data can "e i!orted

and used within AutoCAD Civil 3D so#tware to greatly increase roductivity #or geotechnical engineers.

Users will "e a"le to lot hole locations% create 3D stic$s !odeling strata data at hole locations% and

!odel strata to and "ase sur#aces using geotechnical styling and hatching. The class will also see how

the extension is used to &uic$ly !aniulate a strata sur#ace "y seci#ying what hole data should or should

not "e included and how to raidly create geotechnical sections and auto!atically create "orehole logs

'stris( on the ro#ile view.

Learning ObjectivesAt the end o# this class% you will "e a"le to)

*or!at and i!ort Geotechnical Data

Create% style and !anage +oreholes and ,trata sur#aces

Create dyna!ic geotechnical -ro#iles with +orehole logs

Use AutoCAD Civil 3D #unctionality to edit and !aniulate strata sur#aces

Understand +M concets in relation to Geotechnics

What is the new Geotechnical extension?

The new Geotechnical extension #or AutoCAD Civil 3D 0193% has "een !ade to ease the tas$ o#creating and viewing geological and su" sur#ace in#or!ation.

Geotechnical design is li$e any other engineering ractice% the designs need to "e revised and

re#ined. n !any resects this is !ore the case with geotechnics as the engineer with li!ited

in#or!ation tries to interret the data to "est #it the site. n this resect the tool has "een

designed to &uic$ly dislay data in AutoCAD to allow the user to start !odelling and interreting

the site.

The Geotechnical extension is designed to wor$ with hole locations and geology data% the

#unctionality includes)

!ort and connection to geotechnical data% "oth AG, and C,:

Creating and !anaging +oreholes in "oth lan and !odel sace

Creating and !anaging su" strata sur#aces

-roducing dyna!ic ro#iles with ro2ected "orehole logs on to the!

Geotechnical hatch and style !anage!ent

4xectations should "e set at the right level% the tool will not interret the geotechnical data% it

does not analyse or redict soil strengths% secialist tools are needed #or that% nor does it create

er#ect geological !odels. owever it is a great starting oint #or the !odelling and

visualisation rocess.

The geotechnical extension is still under develo!ent so so!e o# the notes in this handout still

need to "e #inalised at the ti!e o# writing. hoe to include the in#or!ation in this class and add

!ore in the hel and online tutorials o# the roduct% and o# course you can always contact !e.

Format and import Geotechnical ataThe extension is designed to dislay and "and various tyes o# strata not 2ust the geology% so

#or instance it will dislay the sur#aces o# Legend code% shae and !any !ore uni&ue values.

The strata !anager is used to create and dislay strata sur#aces. The sur#aces created are

standard Civil 3D sur#aces% they can "e edited and !aniulated using Civil 3D co!!ands and

The ai! o# the geotechnical extension is to &uic$ly see and understand the site% creatingdyna!ic ro#iles o# the geology strata and "eing a"le to see logs ro2ected on to the ro#ile view

is an excellent aid.

!reate pro)le

Create ro#ile wor$s in the sa!e way as the standard Civil 3D ro#iles% however they have the

extra a"ility to ro2ect the re&uired "oreholes on to the ro#ile view and auto!atically the strata

The co!!and uses a wiBard to create a new ro#ile and align!ent i# necessary.

-ow to create .ones

n a large site investigation "oreholes are o#ten clustered in areas% when loo$ing at sur#aces #or

the whole area you !ay #ind a lot o# !eaningless triangulation #or areas where no data is

availa"le. The sa!e ro"le! can also "e seen on s!aller sites where you have oc$ets o#strata or outcros. 6e need a !ethod to divide the site into aroriate areas. This can "e

done "y using "oundaries.

,ur#ace "oundaries can "e used to create Bones "ut one !a2or li!itation is you can only have

one outer "oundary% however there is a !ethod to su" divide the site.

3. Feeat the rocess "ut #or the sur#ace "elow the lens. ?ou should now have two sets o#

the #eature lines% one #or the sur#ace directly a"ove the lens and one #or the sur#ace

This can "e done "y using either "oundaries or "y exloding ro#ile chain lines and then using
