AutoCAD 3D Practice Drawing for Revolve Command | Create 3D Piston & Piston Ring Video Lecture | A complete Guide to AutoCAD (English) - Design Softwares

in this tutorial we will create this
piston and they will have to create this
object using the wall command for that
at first we will have to create this
hatching portion to switch to 3d
modeling click here select 3d modeling
click on SC isometric and give the UCS
icon command no region enter and from
here select shaded with edges now this
portion we want to create on right plane
from yours change the plane to right
then at first we will create this half
portion of 812 take the line command to
the first point make ortho on zoom it
then here the length is 8 height is 6
again 12 6 then your length is 8 then
take it down that is 6 enter then here
12 enter again 6 then for you we will
take the half enter then we will mirror
it click on modify and select the mirror
Iran select object enter get the first
point give the second point enter then
this vertical line the length of this
vertical line will be 198 - 38 / - it is
198 - 38 divided by 2 that is 80 take
the line come on give the first point
take your cursor down gives a height of
80 and then enter this inclined line is
a tapered line which has a taper of one
in it to work out that taper we'll have
to divide this 50 with the 8 then that
will be the paper on the diameter will
just perform it it is 50 then / taper up
8 enter then this is 6 point drain
different now this taper is on the
diameter now we will have to applied it
on
therefore it will be half of this
divided by two that is 3.1 25 we will
just offset this line by 50 distance
give the Oh enter you the resistance of
50 select this line on this side enter
and from here we will have to come down
by the distance of three point one two
five give the line command L enter take
this point take your cursor below and
use a length of three point one two five
enter and connect this point to this
point and then next will be the opposite
this offset is of twenty distance upset
this line by twenty give the O enter
give the distance of twenty enter offset
it above and and next is this again
twenty offset I can offset this line
offset twenty is there enter select this
line on this side and then this is also
20 offset enter this line twenty enter
then connect all these lines using fill
eight give the fill eight now here fill
it is not specified we will take it
three fill it give the radius of three
enter and then select this line and this
line enter this line and this line
winter this line and this line then here
connect one line line enter from this
point to this point enter then the
revolution axis will be at a distance of
half of the 38 from here take the line
come and track the point take the cursor
below and give the distance of 90 enter
and create one horizontal line now this
object needs to be connected click on
modify and click on join and select all
the objects then press enter if we check
it single object is not created we will
have to join it again click on join
select all the object again into
okay now all the objects are connected
the skip then give the rial command
click here and select lira wall then
select object to the wall this one enter
then click on this object and select
this object then give the angle now if
you want to create sectional like this
then we will have to use the angle of 90
plus 90 plus 90 that is 270 use the
angle up to 70 and make the grid off
then next is this ring this ring is of
six by trail we will create one
rectangle of six by will take the
rectangle command give the first point
then give the dimension the length will
be 12 and height will be six and click
the point then outside diameter of the
ring is 200 that is from top line up to
the center will be hundred just take the
line command tag from the top point and
give the distance of hundred enter in
create one horizontal line in
x-direction enter then move it on the
side and do all this again Raval select
this object to Raval enter object click
on this object and give the angle of 360
degree then for ring there is this cut
is there of three gap a line is there at
45 degree angle take the line command
then give the length we will take a
bigger length we will take the length of
50 then press tab button then give the
angle of 45 degree and then make our
thorn give the length of three enter
again take the line command from here
take your cursor a bow and give the
length of three and connect it to this
portion enter then press fill this
portion principal
take your cursor inside and click there
and get length of 30 escaped we will put
it here move it click on move select the
object enter take this bottom endpoint
and put it on the quadrant and then we
need to cut this portion for that use
the substract command click on this
substract select object to substract
from this object enter select object to
substract enter this cut is created here
is this portion by double clicking we
can send the different colors escape
that's all thanks for watching we will
stop here
