AutoCAD 2015 3D Mechanical Modeling Tutorial | AutoCAD 3D Practice Drawing Video Lecture | A complete Guide to AutoCAD (English) - Design Softwares

in this tutorial we will create this 3d
object using commands that we learn in
previous tutorials at first switch to 3d
modeling by clicking on this button here
and click on 3d modeling then click on
unsaved view select SC isometric then
you see s icon command UCS icon enter no
region then click here and select shaded
with edges then at first we will create
this box of 70 to 145 then 25 right
click on box then specify first corner
then take the cursor away then specify
the width give the 72 then press tab
then give length of 145 in turn give the
direction where you want to go on the
upper side and give the height of 25
then next will be to create this portion
copy this age at a resource of 24 then
again on 24 and the length of this line
is 50 click here on arrow near the
extract edges and select copy edges
click on this edge enter give the base
point give the direction make also on
new direction and give the length of 20
pull I can click on copy select this
edge enter give the base point you the
direction give the distance of 48 enter
then again copy select this age enter
give the base point give the direction
and give the distance of 50 enter then
exit exit click here on the arrow near
the circle and select two points circle
and take this point first point and
second point
then trim the unwanted ages with the
trim command trim enter then enter then
click on the object to trim
and then cut this shape using principle
command click on principle select the
portion give the direction below and
click there and escape and click on 2d
wireframe select this edges unwanted
ages and it is them enter again click
here on shaded with edges the next is
this portion of 36 width and height is
90 minus 25
click on copy Aegis select this age
enter you the base point give the
direction copy it at the distance of 36
escape and click on principle select
this portion give the height of 90 minus
25 it is 64 you enter and I skip the
next is this line is at a distance of 30
from bottom and this line is at a
distance of 24 again copy H select this
bottom edge enter base point direction
of 30 enter again copy select this edge
enter baseman direction and distance of
24 I can copy then the center point is a
at a distance of 42 plus 6 that is 48
select this edge enter give the base
point give the direction give the
distance of 48 then click on exit then
here is the circular portion of radius
30 to create that click on this arrow
below the box and select cylinder give
the center point here at the midpoint
and give the radius of 30 enter then
change the direction click on this axis
endpoint change the direction to go on
this side and give the depth of drill
enter this portion is a hole subtract it
click on this solid subtract select
salutes to subtype from click on this
solid enter then select sorry to
subtract this one enter then here is
this line II enter select the line then
this portion you can remove using
principle click on principle select this
portion
and click on multiple select this other
portion also inter give the direction
and give the distance of 12 s then it is
this line here is select this two lines
and then next is this whole of 24
diameter now this whole is on this
vertical plane for that we will have to
change the plane to change the plane
click here on the world and select the
front plane now XY is aligned with this
surface make the grid off then create
one circle click on the circle then
click on the center point and give the
radius of 12 enter then to create the
hole use the principle command click on
trace pool select inside the circle you
the direction and click there and escape
then next will be this bottom portion
now this is up six height and 72 widths
and 50 depth I can click on this copy
edges select the bottom edge interview
the base point give the direction
vertical direction give the distance of
six again copy select this vertical H
interview the base point give the
direction distance of 72 then exit exit
then to cut it use the principle click
on principle select this portion then
give the direction and then give that
depth of 50 escape then remove these
lines give the e enter select this lines
to be removed enter then next will be to
give the dimensions at first we will
give dimension on this surface to switch
to the surface click here and select
face then select this face and enter
then click on annotate and select the
dimension linear give the first point
give the second point you the location
to increase the size of the dimension
click here dimension style modify then
fit increase scale here suppose we will
make it 15 then in the text portion
we'll take it above and here I also
standard and then in feed tick here draw
dimension line between extension line
then okay includes then we don't want 4
zeros I can click here on dimension
style modify primary units make the
precision to single 0 ok
clothes then next will be this dimension
again linear first point second point
location
when this length of 50 again dinner
dimension give the first point click on
the same point give the location then
next will be we will give dimension to
this portion we can click on home then
click on face select this face and enter
now here these are the dimensions I can
click on annotate then click on linear
dimension then choose the first point
choose the second point Goethe width
then I can enter select this point this
point user 6 enter select this point
this point go down give this dimension
again enter this find this point and
this damage again enter from this
midpoint to this endpoint it is 42 again
enter this point this point location
then next will be this face again click
on home and click here and select the
face option click on this face enter now
it actually got in sled we don't want it
in slide we want it vertical we will
change this UCS using this three-point
option click on this 3 point then give
the first point then give X direction on
this horizontal point then next is y
direction on this vertical line then
give the dimension click on annotate
linear dimension then give here the
width from this point to this point
click here now to repeat this command
again and again give the multiple
command multiple reenter then give the
name of the command dim linear
enter then it will repeat automatically
then give the overall dimension here and
take here then here is the width zoom it
then here is 24 from here to here then
here overall height from here to here it
is 90 then next is the radius dimensions
escape this dimension to be given on
this surface for that again we will use
three point method to change the uses
click on this three point give this
point at the start point this is the X
direction and this is the Y Direction
click on this midpoint then give the
radius dimension click on annotate give
the radius select this arc and give this
radius of 30 make the object snap off so
it will give it accurately then next is
this diameter give that diameter option
click on this circle go inside and click
there then next is this width for that
again from your choose the face option
select this surface enter
then I can annotate give the dimension
linear make the object snap on select
this midpoint to this midpoint click on
this midpoint then to give the color
double click on it and choose the color
from here
thanks for watching we will stop here
