AutoCAD Difficult Complicated Drawing for Mechanical Engineering | Reading Engineering Drawing Video Lecture | A complete Guide to AutoCAD (English) - Design Softwares

in this tutorial we will create pedestal
bearing block front - and tofu first
click on start ring and at first we will
have to create the space for this
drawing using limits command for limits
we will take the value up here the
maximum length is 210 plus 40 plus 14
that is 390 we will take more than that
we will take fan did come up 500 give
the limits command enter then you lower
left corner 0 comma 0 enter the number
right corner per hundred comma 500 enter
then give the zoom all Z enter a enter
now in this drawing at first we will
create these two reference line vertical
and horizontal that we will create free
and we will take this first line make
ortho on enter then again enter to
repeat the command to the first point is
the second
now this is the center point that we are
created then at first we will create
this polygonal object this is a polygon
of fifty radius that is a face-to-face
distance of this polygon is hundred
therefore we will create one polygon
using circumscribe method because fist
of its distance is given with 50 radius
and the number of pages for this polygon
will be one two three four five six
seven eight
that means this is a polygon of eight
edges take the polygon command and give
the number of sides eight enter then
give the center point here then choose
the circumscribed about circle then take
the cursor away and give the radius of
50 enter this polygon is then this upper
portion is at a distance of thirty five
you will offset this line horizontal
line take the offset give the distance
of thirty five enter select this line
give the upper side and click there and
this enter we will create the outside
polygon at a gap of two using offset
command again upset give the distance of
two ENTER select the polygon click
outside and enter then we need to extend
this line up to these vertical lines and
we want to erase these three edges for
that we will have explored the polygon
click on explode select both the
polygons press ENTER then hereit's
ye enter select the edges you want to
raise enter then give the extend command
from here extend then press enter and
click on the edges you want to extend
now this portion is ready at first we
will create the half portion and that we
will mirror on the opposite side now to
create this line at a distance of 155 by
to take the offset command again offset
give the distance of 150 5/2 enter
select this line click on this side then
again this line is at a distance of 300
and then divided by 2 so upset is still
running click on this line gives a key
about 310 divided by 2 and then next is
this line will be at a distance of 40
again take this line give the side here
the distance of 40 enter this horizontal
line will be at a distance of 95 I can
offset 90 for you this horizontal line
on the bottom set then again this line
will go up by this distance 25 you plus
6 that is 31 select the line give the
side give the distance of 31 enter enter
now we have all the reference line only
one line remain is this one this line is
the part of this arc now this arc is of
radius of 32 that means from this Center
this line will be at a distance of 32
will upset that line also offset 32 and
it will be from the this line that means
this line on this side 32 is there give
the side and click there and enter trim
the unwanted edges to create the final
shape give the trim command now we want
to remove all the edges from this edge
then this edge this edge and this edge
enter then remove these edges take the
crossing window enter here also take the
processing word then again this edge is
not required trim TR enter from this
edge enter and click we don't need this
age this age is required up to this line
only up to this line so again we can
trim it trim select the edges and remove
the unwanted
and Tim other portion also so it will be
easy to work then this horizontal line
also we don't need it ahead we will trim
it also from this line
okay here it is of 28 that is 14 on
either side
I can offset it by 14 on either side
then from what M it is a gap of 3 and
after that it is of 18 I can offset Oh
inter gap of 3 enter from here to up up
side and again this line will be at
resistance of 18 enter then again this
is up 44 square that is 22 from the
centerline again this line on this side
at a distance of 22 and then trim the
unwanted edges drink select this line
this line this line enter then use the
crossing edges now here it is a
completely clear use the crossing wage
click at empty place on the right side
and take your cursor on the left side
and click there and it again we don't
need these lines and again this internal
portion and now this portion is ready
then next is this one it is at a
distance of 45 that means from Center it
will be half on either side again offset
45 divided by 2 on either side again
trim it TR inter cutting edges and
object to trim enter then here is the
arc of 6 radius create one circle then
we will trim it circle give the center
point give the radius of 6 then trim it
enter and select the unwanted object and
then here it is a gap of trail and here
also it will be 12 because this gap is
24 therefore hopup 24 will be 12 from
either side it is 12
give the offset of 12 from this line to
this line on this side and from this
line to this side and then fill it here
is the fill a top three relate it fill
it give the radius of 3 enter select the
first line select the second line same
way on this side
fill it enter the radius is already set
select first line select the second line
it is the below line enter select enter
here is one fill it is required we will
give the fill it now here radius is not
specified so we'll assume it to be 3 3
is already there select the first line
select the second line then same portion
is on the opposite side will just mirror
it on the other side we'll just trim the
unwanted ages enter and remove all this
portion and here is it then mirror it
click on mirror select all the object
and get the first point of mirror line
give the second point enter and here
this line is required at a distance of 6
on this side so upset this line by 6
offset 6 enter this line on the bottom
side enter then extend this line e^x
enter give the boundary edges this line
and this line I want to extend it up to
these two lines enter click on the
object enter then create the layers
click on layer properties new layer one
will be Center
choose the color okay
then click here on the continuous click
on load click here and press C on the
keyboard C for center then ok then
choose the center ok
then again new layer you done I can
choose the color ok
then click on the center click on load
click here click H for readin ok then
choose the hidden ok give some color to
this also 0 layer will give it a low ok
then close this now choose the lines
which needs to be done select the lines
with crossing window all this portion
will be hidden then this portion also
then click here and select Hilda escape
now hidden is not properly visible to
make it properly visible you LTS command
enter then increase the scale factor I
will make it 15 then these lines are the
center lines select all the center lines
and click on the center layer and escape
then again layer properties we will
create one more layer for a hatch choose
the color ok and line type will be
continuous only close it then create
match for sure here and give the hatch
command select inside the portion where
you want to apply the hatch then we need
the NC 31
then increase the scale so was 15 enter
increase it furthermore 30 okay then we
want this on the hatch layer click here
on the properties click here and select
hatch layer and click on close as
creation then we need this centerline
outside a bit click on the blue box and
pull it outside click go outside and
click again same way for this portion
click take it outside okay then escape
now in this way we need to create this
portion here so we will just extend this
line up to this line click on extend
select the boundary up to this line
enter click on the line you want to
extend enter now we need this portion to
be continuous we will break this line at
this point click on break at point
select the line then give the point this
point then we need a fill it here and we
need line type of this line to be
continuous click on match properties
select this source object select this
destination object enter then fill it it
give AF enter select first lines like
second line in the next tutorial we will
create the plan thanks for watching we
will stop
