AutoCAD 3D Bridge Tutorial | AutoCAD 2010 Video Lecture | Complete Course of AutoCAD 3D (Basic & Advanced) - Software Development

in this tutorial we will see how to
create 3d bridge in AutoCAD so let's
start so first we will see to southeast
isometric then you use this icon no
region enter so we want to work on right
lens so go to view say right then create
two reference line one horizontal line I
will create suppose of 45 n then I will
copy this line upward by 10 distance so
this is the limit of my bridge then when
we take a line on the left then I will
copy this line at desired distance as
you want so as I want this line to be on
point 5 distance then I will copy this
line on suppose for 20 distance now I
will create a two point circle so I will
go back to home and select the circle to
point and I will create one to point
circle here on the edges then I will
move this circle down so this will
define the profile arches of the bridge
so I will trim the unwanted areas so I
do not want this I do not want this now
I will cover copy this shape copy this
arch as many time as you want
what's your requirement
okay I will copy all of that
okay
then last one
okay so this arches are defined then I
want this line to be at point for you
again last line so I will just offset it
on pointer distance and I will just
connect this lines using fill it selects
first lines lexicon line select first
lines lick second line so in this way
this arch is ready then you can convert
this arch into 3d using place full just
select Krishna command go inside the
shape click inside the shape once it is
highlighted then give the width suppose
I want the width to be for you so I will
give the five it or I will take it say
one okay place will give the good give
them you top eight suppose then use this
in conceptual visual style so in this
way the chars are ready then I want
protection walls on the sides so I will
just use the copy edges so I will say
copies select the enter baseline
direction so I want protection all up
point for you thickness same way I want
this on this side also so I will just
copy this line copy base line direction
point five thickness okay then I will
convert this wall into 3d is in place
full protection walls so I will just
take my cursor inside those walls just
zoom
preschool go inside the give the height
suppose I want I to be up 0.50 so I will
just give the height of 0.5 okay then
now this side also I will put a spoon
just say preschool then go inside the
area give the height I talk point for
you
okay so small protection walls are ready
then I will I want to put pipes on to
that or rods on on that so I will just
create one circle okay now I have to
work on top line so I will go back to
view and see top just select top then I
will create a circle for definition of
rod or pipe so I will create a pipe op
point not for you diameter radius then I
will trace pull this pipe so I will come
back to home and say press pull and go
inside the circle and give the height
suppose I want a height of one one point
for you so this vertical rod is ready so
I will move it and put on the wall so
just select move select select the
bottom Center and put it on the middle
of the wall
make ortho what we just undo okay or
thought then zoom on the corner and just
catch the midpoint okay
now I will move it inside of the action
inside so does I will move it make the
or thorn again so I will keep it here
now same I want on this side also so I
will copy enter give the base kind this
side this corner and I will put it with
this reference to this corner so two
rods are ready now so I will erase these
rods using 3d array just select clear is
linked both the rods then you enter then
type of pair is rectangular number of
roots so number of rules I want to be
suppose 45 then column one level one gap
between rows is one point five meter or
suppose one meter so in this way this ad
is ready up to the end then I will just
create a line on the top connecting the
first and last pipe so I will take the
center of this road and I will go up to
the last rod so just plan it
and click on the center of the last rod
so this line is ready okay then I will
create one circle a point not for you
then I will just sweep this circle shape
like this circle then enter then sweep
path I will take this line just I
created so this top pipe is already then
I will copy this pipe at 175 distance so
I will say copy this pipe give base
point give the direction below I want
you to be copy at point 75 so this two
pipes are ready so I will copy this pipe
on this side also so just copy take the
basement of this corner this side
endpoint of this and the data reference
create with respect to this endpoint on
this side so in this way protection
piping is ready so you can remove the
unwanted lines and unwanted parts just
erased those then then you can apply the
material by choosing here from here
suppose I want something nationally
nationally so flooring finish every door
windows concrete masonry okay so I want
this as another unit apply it on the
bridge enter now material is not visible
so just go to render and say here metal
and texture on so it look the bricks are
looking very large in size so we can
reduce their size using metal mapping
just click on metal map say box then
select the bridge enter then address the
size using these blue arrows click on
that and come closer so the
brick size will reduce same way I want
to reduce in height to so I will click
up arrow and go down so just time on
okay so this is upside then crosswise
also I want to reduce so click on this
clock cross side arrow and go inside
adjust the material adjust the size so
in this way you can apply material also
just press escape to come out so bricks
are applied
same way you can apply a meta but steel
on the rods so door and window select
this steel galvanized just zoom out and
just click the window and this all so
steel galvanized is also applied so in
this way we have created a bridge so
that is all we will stop here thanks for
