AUTOCAD 3D HOUSE - CREATING A LOUVERED VENTILATOR | AUTOCAD 3D VENTILATOR | AUTOCAD RENDERING Video Lecture | How to create 3D House using AutoCAD? - Software Development

in this tutorial video we will see the
procedure to create a lured ventilator
this is just a supplementary video to my
series of video tutorials on 3d house
modeling on this 3d house on the right
wall face I would like to create two
lured ventilators so I'll generate a
view in which the right face is exposed
so I'll click on this particular hotspot
of the viewcube to generate a south-east
isometric and I'll just click on orbit
this navigation tool and I'll select the
orbit and I'll orbit the view a bit and
you can see the provisions where in the
ventilators are to be created now let me
switch over to a realistic
representation to see the openings
clearly this opening is made by creating
a box having the dimensions of the
ventilator the length of the ventilator
is 100 centimeter and its height is 75
centimeter so I have made such a box and
I have given a thickness equal to the
thickness of the wall which was 24
centimeter then I have subtracted that
particular box from the wall to get this
cut out if you need any clarifications
on making such a cut out you can refer
to my previous videos on making windows
and those in the same tutorial series
ok so let's create the ventilator we
will start with the ventilator frame
before we start creating the frame we
have to make the 3d window frame layer
as the active layer because I want the
ventilator frame to appear on the same
layer of the window frame ok now we have
to align the UCS on this face so I'll go
to view tab and I'll click on UCS
three-point option ok
I'll click on this icon or else you can
give UCS command and I'll select the
3-point option I'll keep my origin here
x-direction here and y-direction here my
use is kept over here now now we should
make sure that your dynamic you seeis is
off when you trace the polyline profile
to create the frame
now I'll go to home tab and I'll select
the polyline command from the draw panel
now it'll ask you to pick the vertices
I'll pick the vertices over here one two
three fourth well Tex I'll pick here
then I'll just give a close to complete
the polyline profile this is the profile
which you have traced then I'll give an
offset command so I'll select offset
then it'll ask you for the offset
distance I'll give six as offset
distance because that is a frame
thickness or the ventilator and I'll
select this as a object offset and I'll
pick the side to create the offset now
I'll go to extrude command and I'll
select these two profiles and I'll
extrude it through a distance of minus
ten units because that is a thickness or
the frame now I'll go to subtract from
the solid editing palette and I'll
select the outer box then I'll just give
an enter then select the inner box and
enter so we have made an outer frame of
the ventilator now we have to create a
partition frame for that I'll use
polyline command again and I'll pick my
first point here on this mid and second
point on the mid of the bottom edge of
the frame
now I'll again go to offset okay and
I'll give an offset distance of three
units which is half the frame width so
three on this side and three on this
side I have made offsets now the center
profile is no longer required so you
select that profile then you can erase
it
now we have to complete this profile as
a close profile so I'll give polyline
and I'll select these two endpoints okay
then you can draw another polyline
connecting these two endpoints and you
can go to modify panel and you can
select join from here okay and you
select all the profiles to be joined as
a single profile or else you can use P
edit join option just as we have done
earlier
now you can extrude this profile as well
okay so I went to extrude then I'll
select this profile to be extruded you
give the same extrusion thickness as -10
okay now we can make these two objects
as a single object by performing a union
operation so just click on Union and you
select this and this that is the outer
frame and the partition frame to make a
single object out of it so this is the
frame of the ventilator
let's create the lowers next so I'll
change my visual style to 2d wireframe
then I'll keep the 3d window glass layer
as the active layer because I want my
lure to appear on this layer now I'll
create the profile of the louver but
before I create the profile
I must align the UCS on the side face of
the ventilator so I'll go to view tab
and I will click three point option of
the UCS command and I'll keep my origin
here X in this direction and Y in this
direction now you can see that the XY
plane is aligned on the side face or the
ventilator so I'll select a rectangle
from here and I will pick my first
corner on the screen and I can go to
dimension option so I'll click on
dimensions when I'm asked to give the
length I can give 12 okay when I'm asked
to give the width I can give one now
when I'm asked to give the side or to
pick the opposite corner you can pick
any corner I'll pick over here so I've
completed the rectangle now I can go to
move command and I can select this
particular rectangle and I'll pick the
base point as this end point and the
second point as this end point okay it
is moved and it is aligned now I can
give a rotate command and I'll select
this rectangle when I'm asked to give
the base point I can select this as a
base point and I'll give a rotation
angle of minus 35 degrees because I want
the rotation to take place in the
clockwise direction okay so it is
rotated now you can go to extrude
command and I'll select this profile and
I can give the height of extrusion when
I'm asked I don't have to give any
numeric values but I can just pick a
point over here to specify the height of
extrusion so you have made the first
louver now you have to generate multiple
copies of this louver
in the negative y direction so the
commander's array so you can give array
and can select array classic okay if you
are using older versions of AutoCAD you
can give array in 2013 its array classic
it will let you generate multiple copies
so when I'm asked to keep the number of
rows I can give a nine number of columns
I can give one
and the raw offset that is distance
between individual element in a row is
minus seven I must give it as minus
seven because I want the array formation
to take place in the negative
y-direction you can just select the
objects to be arrayed okay and you can
just preview the array so you have made
multiple copies okay and you can just
give okay to exit this array command now
we have to copy these louvers onto the
other side
for that I'll go to copy command and
I'll select all these louvers using a
standard window and I'll select my base
point as this point and I'll pick my
second point as this point so it is
copied now we will add a few materials
on this ventilator so I'll change my
representation to realistic and I'll
click on a render tab and I'll select
material browser in the material browser
you have a number of materials which
comes along with the software is
available and you can select the
individual objects then you can click on
the material and assign it so I'll
select the frame okay then I'll go to a
wood just click on wood you will see
various types of wooden materials
available in this wooden panel materials
and I'll select this paneling one for
example then you just right click and
click on as line to selection
the moment you click on that this outer
frame will get that particular material
and I would like to assign a glass
finish for these louvers to assign the
material you have to select the louvers
first so I'll switch over to wireframe
representation because in this
representation you can make more
accurate selections and using a standard
window I'll select all the lowers in one
click then I'll go to glass material I
have different types of glazing material
I'll select a blue glazing for example
and I right click here then I'll click
on assign to selection and these louvers
have got this glass material and if you
want to see the change you should switch
over to a realistic representation so
now you have a preview of the material
the actual material feel you
get only when you go for final rendering
and now I have to copy this because I
have another provision over here so I'll
copy the entire ventilator and I'll keep
it over here so I'll go to Home tab and
I'll select copy and using a window I'll
perform a copy okay I will just copy
this and I'll select this as a base
point and this is a second point now you
have got the copy of the ventilator onto
the other provision so this is how you
make a wind later with Lewis using
AutoCAD 3d the realistic feel of this
materials you will get only when you go
for final rendering for that I'll go to
render tab and I'll click on render
region option here okay so it'll ask you
whether you want to install this image
library and all that you can just cancel
it for the time being and you can pick
two corner points to define the window
okay because I want the area that is
captured using the window to be rendered
just click on that and AutoCAD will
start rendering you have to wait for
some time for the result to appear in
fact you will get more realistic
rendering only when you assign certain
parameters such as lights cameras etc so
we'll have an exclusive video tutorial
on rendering on a later stage this
simple procedure can be used not only on
ventilators but on those windows and
cabinets wherever you see the presence
of viewers please do make a try and get
